- heycam: as a bit of background, we met with Sairus a year ago at Microsoft and we discussed in persons
- 22:12:40 [Cyril]
- ... some issues regarding the SVG in OpenType proposal
- 22:12:48 [Cyril]
- ... I recently started looking at it
- 22:12:56 [Cyril]
- ... in the meantime Sairus has suggested some spec text
- 22:13:14 [Cyril]
- ... and I thought a good way to engage and resolve differences was to write down what we have in our implementation
- 22:13:25 [Cyril]
- ... and start to converge both proposals
- 22:13:32 [Cyril]
- ... I'm not looking for any decision today
- 22:13:38 [Cyril]
- ... I don't want to publish
- 22:13:57 [Cyril]
- ... now
- 22:13:58 [AlexD]
- AlexD has joined #svg
- 22:14:10 [Cyril]
- ... edwin who worked on the implementation as an intern
- 22:14:16 [Cyril]
- ... wrote down the behavior that we have
- 22:14:26 [Cyril]
- ... last week I turned the description more like a spec
- 22:14:35 [Cyril]
- ... and sent it to the list last week
- 22:14:37 [heycam]
- http://dev.w3.org/SVG/modules/fonts/SVG-OpenType.html
- 22:15:40 [heycam]
- That's Edwin's and my write up.
- 22:15:42 [heycam]
- http://lists.w3.org/Archives/Public/public-svgopentype/2012Aug/att-0000/SVG_in_OpenType_WD_2012-08-07.pdf
- 22:15:46 [heycam]
- That's Sairus' write up.
- 22:17:02 [Cyril]
- heycam: I think they are not terribly different
- 22:17:06 [Cyril]
- ... there are a few main differences
- 22:17:11 [Cyril]
- ... I've not listed them
- 22:17:18 [Cyril]
- ... do you want to discuss them?
- 22:17:29 [Cyril]
- krit: the number of SVG documents is a good start
- 22:17:49 [Cyril]
- heycam: I think Robert said on the ML and gave some reasons to support multiple documents
- 22:18:05 [Cyril]
- ... in our proposal you have an index of byte ranges that correspond to each document
- 22:18:14 [Cyril]
- ... and you indicate which range of glyphs are in the document
- 22:18:20 [krit]
- nick: sairus
- 22:18:53 [Cyril]
- ... I believe in Sairus' proposal there is a single offset/length pair to indicate where the single compressed document is
- 22:19:00 [Cyril]
- sairus: I sent a report
- 22:19:00 [sairus]
- s/krit/sairus/
- 22:19:18 [Cyril]
- sairus: the pros and cons of the multiple svg documents
- 22:19:21 [Cyril]
- ... has been discussed
- 22:19:34 [Cyril]
- ... and a new pro was subsetting glyphs
- 22:19:56 [Cyril]
- ... I think the multiple svg documents approach has multiple pros (multiple dictionnaries ...)
- 22:20:08 [Cyril]
- ... emoji in one document
- 22:20:13 [Cyril]
- ... latin in another document
- 22:20:32 [Cyril]
- ... the issue of timeline has been brought against, not to go
- 22:20:52 [Cyril]
- ... I don't know how you feel about the timeline stuff in the proposal from last Friday
- 22:21:03 [Cyril]
- ... If we go with multiple documents it is fine with me
- 22:21:11 [Cyril]
- heycam: the main advantage I can think of
- 22:21:23 [Cyril]
- ... splitting avoids the overhead of having one document running
- 22:21:34 [Cyril]
- ... for all of the glyphs in the document
- 22:21:49 [Cyril]
- ... you probably want to split the document to reduce the number of glyphs active
- 22:22:11 [Cyril]
- sairus: I can imagine big fonts and relate problems
- 22:22:22 [Cyril]
- AlexD: you can also cache easily
- 22:22:36 [Cyril]
- ... caching part of a document is different
- 22:22:58 [Cyril]
- cabanier: the proposal is not to have one document per glyph?
- 22:23:16 [Cyril]
- heycam: not explicitely, it would be good to have guidelines to explain how to structure documents
- 22:23:27 [Cyril]
- cabanier: yes because resource sharing is a problem
- 22:23:38 [Cyril]
- heycam: resource sharing is not adressed in my document
- 22:24:08 [Cyril]
- ... there would be no way to share across documents, we could define extra tables with URI (blob or multi part)
- 22:24:15 [Cyril]
- ... I'm not sure it's worth at this point
- 22:24:36 [Cyril]
- AlexD: there is no problem with the one document approach, but it's more work to use existing font cache
- 22:24:52 [Cyril]
- krit: I'm not sure the font engine would be used for SVG
- 22:25:01 [Cyril]
- AlexD: I would hope they are used, because of performances
- 22:25:11 [Cyril]
- ... we should be thinking of speed and performances
- 22:25:31 [Cyril]
- heycam: there is a difference between reusing existing font cache mechanism and designing a new one
- 22:26:09 [Cyril]
- sairus: by subsettability I meant that you can create a font with just 5 glyphs
- 22:26:15 [Cyril]
- ... for embedding in another document
- 22:27:03 [Cyril]
- heycam: I remember us dicussing that last time, in one document, subsetting changes the document order and so style might be affected
- 22:27:07 [Cyril]
- ... it's not trivial
- 22:27:17 [Cyril]
- cabanier: what kind of style would be affected ?
- 22:27:32 [Cyril]
- heycam: nth child
- 22:27:41 [heycam]
- s/heycam/AlexD/
- 22:27:55 [Cyril]
- cabanier: I thnk the font should be independent of the number of child
- 22:28:09 [Cyril]
- heycam: the styling of any element shouldn't change if you remove any element
- 22:28:19 [Cyril]
- cabanier: yes, maybe
- 22:28:36 [Cyril]
- cabanier: if you use the 5th letter, it's not going to be the 5th child
- 22:28:56 [Cyril]
- heycam: but presumably you are writing styles because they make sense with the document
- 22:29:10 [Cyril]
- AlexD: that should be strongly discouraged
- 22:29:34 [Cyril]
- heycam: the work to be done wouldn't be too bad
- 22:29:54 [Cyril]
- sairus: subsetting complexity is already there in truetype
- 22:30:13 [Cyril]
- ... a subsetter has to follow dependencies in truetype
- 22:30:30 [Cyril]
- ... guidelines for SVG may be needed, but you have to take TrueType complexity into account
- 22:30:39 [Cyril]
- cabanier: I don't think there is an issue with the order
- 22:31:03 [Cyril]
- heycam: I would be happy with a warning to authors to avoid styling documents that change with order
- 22:31:05 [dmitry]
- dmitry has joined #svg
- 22:31:13 [Cyril]
- ... and also warn them to do subsetting properly
- 22:31:50 [Cyril]
- cabanier: what happens if you open that svg file
- 22:31:59 [Cyril]
- heycam: you could set the viewport to view something
- 22:32:18 [Cyril]
- heycam: you could structure your document to view the svg in some way
- 22:32:26 [Cyril]
- cabanier: or use style= display none
- 22:32:38 [Cyril]
- heycam: display none on an ancestor of the glyph definition
- 22:32:57 [Cyril]
- ... I woud want to behave just like use
- 22:33:19 [Cyril]
- ... use elements are displayed even if display none is set on the referenced ancestor
- 22:34:03 [Cyril]
- heycam: one of the big differences btw the 2 proposals, is that you have it compressed, we don't
- 22:34:25 [Cyril]
- ... what happens when you serve a document, it may be compressed
- 22:34:29 [Cyril]
- AlexD: WOFF is compressed
- 22:34:58 [Cyril]
- sairus: any place fonts can be embedded there are ways to compress with more than WOFF or HTTP compression
- 22:36:15 [Cyril]
- AlexD: we should mandate compression if we allow it, it shouldn't be optional
- 22:36:18 [Cyril]
- heycam: agree
- 22:36:29 [Cyril]
- ... It might make it difficult to pass to the XML parser
- 22:36:41 [Cyril]
- ... you have to allocate the uncompressed version in memory
- 22:36:53 [Cyril]
- AlexD: no you decompress it and stream it to your parser
- 22:37:13 [Cyril]
- heycam: I don't have any fundamental objections with having the tables compressed
- 22:37:20 [Cyril]
- ... I assumed it was simpler not to
- 22:37:48 [Cyril]
- nikos: one of the other differences is the SVG glpyh class
- 22:37:52 [Cyril]
- ... this is a nice thing
- 22:38:02 [Cyril]
- heycam: yes this is the other major difference
- 22:38:20 [Cyril]
- nikos: it allows you to know if the glyph is present without loading the file
- 22:38:28 [Cyril]
- sairus: it is a cache
- 22:39:30 [Cyril]
- sairus: I defined it to know which glyphs were defined with SVG in this font
- 22:40:02 [Cyril]
- ... you could imagine clients that don't support animation would appreciate to know it upfront
- 22:40:18 [Cyril]
- heycam: our table has index entries to say which documents cover which glyphs
- 22:40:36 [Cyril]
- ... it doesn't say if the glyph is there, if it is, it has to be in this document
- 22:40:41 [Cyril]
- ... so you'd have to open it
- 22:40:58 [Cyril]
- ... the glyph range could be more than the glyphs in the document
- 22:41:05 [Cyril]
- ... there might be holes in the range
- 22:41:20 [Cyril]
- the table doesn't define the holes
- 22:41:39 [Cyril]
- ... say a single document, range 1 to 64000 but with only one glyph in it
- 22:42:02 [Cyril]
- sairus: the issue is that it involves calling the svg renderer
- 22:42:19 [Cyril]
- ... we should make it simple for clients to take the first step
- 22:42:35 [Cyril]
- ... really making it easy, no parsing unless they have too
- 22:42:40 [Cyril]
- s/have too/have to/
- 22:43:03 [Cyril]
- heycam: I feel the distinction animated/static and determining if a glyph is there at all are two different things
- 22:43:18 [Cyril]
- ... right now, you have to search the glyph id
- 22:43:28 [Cyril]
- ... I can see the benefit of having the right range in the table
- 22:43:48 [Cyril]
- heycam: I think the sharing is a separate thing as well
- 22:43:58 [Cyril]
- sairus: we want to be precise in the index table entry
- 22:44:10 [Cyril]
- heycam: I think ti would be better with your proposal
- 22:45:02 [Cyril]
- ed: when you define you SVG glyph can you define data coming from the CFF or glyph tables
- 22:45:20 [Cyril]
- s/define/reference/
- 22:45:27 [Cyril]
- sairus: go across glyph technologies ?
- 22:45:41 [Cyril]
- ... so far they've been seen as mutually exclusive
- 22:45:50 [Cyril]
- heycam: no proposal have this feature
- 22:46:11 [Cyril]
- sairus: I can see it would be useful, for instance style with CSS normal glyphs
- 22:46:35 [Cyril]
- ed: I could see use cases were you want multi colored glyphs without duplicating the glyph data
- 22:46:46 [Cyril]
- heycam: it would require special adressing
- 22:46:54 [Cyril]
- Cyril: fragment identifiers ?
- 22:47:19 [Cyril]
- sairus: it is probably not worth adding the complexity
- 22:47:28 [Cyril]
- heycam: I'm sure it would be possible to make it work
- 22:48:38 [Vlad]
- Would SVG renderer allow importing binary outline descriptions into XML-based SVG document? IF not, I don't <yet> see a use case for this references
- 22:48:40 [Cyril_]
- Cyril_ has joined #svg
- 22:48:46 [Cyril_]
- cabanier: is it written that you can't write reference to external resources?
- 22:48:50 [Cyril_]
- heycam: yes
- 22:49:16 [Cyril_]
- sairus: could be an extension in the future, not required for v1.0
- 22:49:19 [Cyril_]
- heycam: (reading vlad's comment)
- 22:49:45 [Cyril_]
- Vlad: you would need to invert them ?
- 22:50:27 [Cyril_]
- Vlad: without being able to enforce it, I don't see the use of the reference
- 22:50:47 [Cyril_]
- heycam: the advantages I could see, is avoiding to duplicate
- 22:50:53 [Vlad]
- s/invert/import
- 22:50:54 [Cyril_]
- ... it's basically an optimization
- 22:51:14 [Cyril_]
- ... you'd have to define how path animations would work
- 22:51:31 [Cyril_]
- cabanier: hinting is another thing
- 22:51:43 [Cyril]
- ed: I don't think that's what all browsers do
- 22:52:43 [Cyril]
- heycam: I feel like it is a reasonnable way to support animated and non animated with the same definition
- 22:52:54 [Cyril]
- ... you render the document without the animation element
- 22:53:16 [Cyril]
- ... I might have written a tiny example, how you could animate a circle radius to 10 and back
- 22:53:32 [Cyril]
- ... for the non animated version, you ignore the animation and render the r attribute base value
- 22:53:33 [ed]
- s/ I don't think that's what all browsers do/ I don't think all browsers apply hinting if the outlines are fetched for rendering (depending on scale)/
- 22:53:49 [Cyril]
- cabanier: you limit yourself to the non animated case as a snapshot
- 22:54:07 [Cyril]
- birtles: you could have a set that turns the glyph to something different at the beginning
- 22:54:49 [Cyril]
- sairus: I think both main proposals have converged to having a single glyph definitions and you render the animation or not
- 22:55:00 [Cyril]
- ... just like when you print an animated svg document
- 22:55:21 [Cyril]
- heycam: people design graphics in this way for viewing animated content in IE
- 22:55:41 [Cyril]
- heycam: there is a way to switch on to some different graphics
- 22:56:07 [Cyril]
- Cyril: I don't know what we have decided with the snapshotTime
- 22:56:23 [Cyril]
- birtles: this requires to apply the animation
- 22:56:37 [Cyril]
- AlexD: yes, you need more than a static engine
- 22:57:24 [Cyril]
- ... I don't think snapshotTime is a very good tool for that
- 22:58:09 [shepazu]
- q+
- 22:58:10 [Cyril]
- heycam: if an app using the font wants to say render the font statically with a snapshot time
- 22:58:16 [Cyril]
- ... they'd be able to do that
- 22:59:10 [heycam]
- ScribeNick: heycam
- 22:59:19 [heycam]
- shepazu: when I was reading the font spec… what file are the fonts defined in?
- 22:59:27 [heycam]
- … are they defined in the file that is the font file?
- 22:59:30 [heycam]
- … or can they be external?
- 22:59:34 [heycam]
- AlexD: they would be in the font file
- 22:59:57 [heycam]
- shepazu: it seems almost arbitrary that they need to be in the font file, rather than the document that is being rendered
- 23:00:22 [heycam]
- … what's the limitation that says we can't reference them internally?
- 23:00:33 [heycam]
- … in which case how does this save us anything from SVG Fonts as they are defined?
- 23:00:48 [heycam]
- cabanier: it's backward compatible; the user doesn't know it's SVG
- 23:00:52 [heycam]
- … the font just renders
- 23:01:01 [heycam]
- shepazu: but isn't that also the case with what I said?
- 23:01:16 [heycam]
- cabanier: this is not just for HTML, but everywhere
- 23:01:57 [heycam]
- shepazu: one of the use cases I get mailed off list, is that people like to be able to define the SVG font in the file itself
- 23:02:32 [Cyril]
- heycam: the advantage of not having them in the document is to not be able to modify them at runtime
- 23:02:55 [Cyril]
- shepazu: it should be explicit in the spec
- 23:03:13 [Cyril]
- AlexD: the big reason is to support complex scripts
- 23:03:20 [Cyril]
- ... there is no advantage for latin
- 23:03:31 [Cyril]
- ... svg fonts can be external documents
- 23:03:36 [Cyril]
- scribenick: Cyril
- 23:03:52 [Cyril]
- heycam: if there are particular reasons why we are choosing this model, it should be clarified
- 23:04:02 [Cyril]
- Vlad: this is not really going to be part of the SVG spec
- 23:04:11 [Cyril]
- ... this is going to be in the OpenTYpe spec
- 23:04:31 [Cyril]
- AlexD: it opens up the possibility of HTML to use SVG for text
- 23:04:41 [Cyril]
- ed: but you can already use SVG fonts with HTML
- 23:05:08 [Cyril]
- sairus: next point, I'd like to discuss is
- 23:05:23 [Cyril]
- ... so far the Adobe proposal doesn't change the SVG spec
- 23:05:33 [Cyril]
- ... we want to ease the burden of implementations
- 23:05:54 [Cyril]
- ... there are some aspects of the SVG spec that need to be changed in the Mozilla proposal
- 23:06:06 [Cyril]
- ... the glyph id is it absolutely needed ?
- 23:06:14 [Cyril]
- ... and the color by number schemes ?
- 23:06:48 [Cyril]
- heycam: we've started to add the new paint values inSVG because they are useful in other context (markers)
- 23:06:57 [Cyril]
- ... we have new keywords: contextFill and contextStroke
- 23:07:11 [Cyril]
- ... you reference the text element that is using the glyph
- 23:07:27 [Cyril]
- ... you can use them in the fill or stroke of the glyph
- 23:07:46 [Cyril]
- sairus: in the proposal there is a single fill or stroke
- 23:07:51 [Cyril]
- heycam: yes, no passing of arrays
- 23:08:21 [Cyril]
- sairus: I can have the base of a lower case i be rendered with a color and the dot with another color
- 23:08:54 [Cyril]
- heycam: you could define a gplyh with some parts filled in context fill and some other parts to be always red for instance
- 23:09:30 [shepazu]
- (what about passing in "parameters"?)
- 23:09:45 [Cyril]
- ... you can override with colors specified in the font document
- 23:09:50 [Cyril]
- AlexD: what about gradients ?
- 23:10:07 [Cyril]
- heycam: contextFill uses the same gradient
- 23:10:37 [Cyril]
- AlexD: a gradient right now can be applied to a chunk of text
- 23:11:02 [Cyril]
- ... I don't see how you could do that with the glyph based gradient
- 23:11:27 [Cyril]
- heycam: we've made it work
- 23:11:39 [Cyril]
- ... the rendering of the glyph is not passed to a font engine
- 23:11:45 [Cyril]
- ... normal glyphs only
- 23:11:54 [Cyril]
- ... svg glyphs we paint them ourselves
- 23:11:59 [heycam]
- http://dev.w3.org/SVG/modules/fonts/SVG-OpenType.html#value-context-fill-stroke
- 23:12:08 [Cyril]
- ... so the gradient is smoothly applied to the run of text
- 23:12:17 [Cyril]
- ... have a look at example 3
- 23:12:42 [Cyril]
- s/contextFill/context-fill/g
- 23:12:49 [Cyril]
- s/contextStroke/context-stroke/g
- 23:13:27 [Cyril]
- cabanier: that's when the gradient is in the referencing document, and it would be different when the gradient is in the svg glyph document
- 23:14:04 [Cyril]
- sairus: we'd like fonts to come with various swatches of predefined colors (extended to opacity ...) that go together well
- 23:14:19 [Cyril]
- ... and the tool would offer these color options
- 23:14:27 [Cyril]
- ... each of them would have a name id
- 23:14:34 [Cyril]
- ... so that the user interface could show them
- 23:14:48 [Cyril]
- ... what would it take to do that?
- 23:15:09 [Cyril]
- heycam: without having thought about it too hard, using CSS variables could be the way to do it
- 23:15:18 [Cyril]
- ... how do you pass them in
- 23:15:33 [Cyril]
- ... same thing as parameters
- 23:15:59 [Cyril]
- sairus: are you saying the CSS thing could coexist with the context-fill and context-stroke ?
- 23:17:02 [Cyril]
- heycam: when you have text in the outer SVG document (SVG text) you can fill and sttroke it. In HTML you can only fill, but there are discussion to have stroking
- 23:17:11 [Cyril]
- ... I feel that those 2 operations are special
- 23:17:26 [Cyril]
- ... separate parameterized palette entries
- 23:17:35 [Cyril]
- Vlad: I support the use case that sairus presented
- 23:17:39 [Cyril]
- ... we should make it stronger
- 23:17:58 [Cyril]
- ... designers with specific colors in mind, wouldn't want these colors to be modified by the outside
- 23:18:07 [Cyril]
- ... just like they don't want the outlines to be modified
- 23:18:17 [Cyril]
- heycam: it is totally fine
- 23:18:38 [Cyril]
- ... if you specify a fixed color value, that's it, can't be overriden
- 23:18:45 [Cyril]
- ... same thing for patterns
- 23:19:09 [Cyril]
- sairus: stroking can alter the look of the glyph
- 23:19:19 [Cyril]
- ... OpenType doesn't mention stroking
- 23:19:51 [Cyril]
- ... OpenType gives an alpha mask and you're free to color it
- 23:20:07 [Cyril]
- ... I'm not particularly convinced that context-stroke is useful
- 23:20:30 [Cyril]
- heycam: for me, filling and stroking are the basic primitives that you can do to shapes
- 23:20:42 [Cyril]
- cabanier: but you won't be able to stroke an svg glyph
- 23:20:48 [Cyril]
- heycam: you will
- 23:21:18 [Cyril]
- ... you will not stroke the outline
- 23:21:54 [Cyril]
- ... you need to construct the document with stroke in it, if you want it
- 23:22:14 [Cyril]
- sairus: I'd like to have a place for palette in the font spec
- 23:22:23 [Cyril]
- ... I don't think it'll be implemented right now
- 23:22:42 [Cyril]
- ... but it needs to be speced
- 23:22:55 [Cyril]
- ... what would eb the values
- 23:23:01 [Cyril]
- heycam: that's what Leonard asked
- 23:23:11 [Cyril]
- ... what we have is very web specifi
- 23:23:26 [Cyril]
- ... we need to define what the context is outside of a web context
- 23:23:38 [Cyril]
- sairus: you said SVG has color spaces ?
- 23:23:47 [Cyril]
- heycam: CMYK, spot colors ..
- 23:24:05 [Cyril]
- ... in SVG 2, there is a new color syntax to refer to ICC colors, LAB, ...
- 23:24:16 [Cyril]
- ...I'm not sure all of that will be implemented in browsers
- 23:24:29 [Cyril]
- ... you can have a fallback sRGB
- 23:24:45 [Cyril]
- cabanier: the browser would not have to render the spot color, but a printer would
- 23:24:53 [Cyril]
- sairus: how would it look like
- 23:25:21 [Cyril]
- Cyril: you can use solidColor to make palettes
- 23:25:23 [heycam]
- https://svgwg.org/svg2-draft/color.html
- 23:25:50 [heycam]
- https://svgwg.org/svg2-draft/pservers.html
- 23:26:16 [Cyril]
- heycam: you can reference colors by name (gradient, patterns or solid colors)
- 23:26:34 [Cyril]
- ... I'm not sure that would be the best way to do it: defining set of names controlled by the outside
- 23:26:45 [Cyril]
- ... there is a proposal for parameters
- 23:26:58 [Cyril]
- ... that could be better or some information in the table header
- 23:27:19 [shepazu]
- q+
- 23:27:22 [Cyril]
- sairus: that is one way SVG would be extended
- 23:27:30 [Cyril]
- ... but not only for fonts, right?
- 23:27:45 [Cyril]
- heycam: we've added taht to the main SVG spec, because they are useful in other situations
- 23:28:01 [Cyril]
- ... markers to be style the same way as the objects they are put on
- 23:28:26 [Cyril]
- sairus: what about glyph id
- 23:29:43 [heycam]
- ScribeNick: heycam
- 23:29:49 [heycam]
- shepazu: I'm wondering about non-Web contexts
- 23:30:02 [heycam]
- … do we expect SVG glyphs to be used widely in non-Web contexts?
- 23:30:15 [heycam]
- … and what does it mean for these context-* values in non-Web content
- 23:30:29 [heycam]
- … there's a lot of stuff to implement SVG, even with the amount that's specified in the SVG-in-OpenType proposal
- 23:30:33 [heycam]
- … are we going to cut that down?
- 23:30:57 [Cyril]
- heycam: we haven't really talked about what subset of SVG is required
- 23:31:16 [Cyril]
- ... should we annotate glyphs with versions of the svg spec
- 23:31:53 [Cyril]
- ... on the web we add new features and old browser do some thing, maybe in font, it could be different handling, I don't knonw
- 23:32:12 [Cyril]
- ScribeNick: Cyril
- 23:32:25 [Cyril]
- AlexD: are you expecting different engines than web engines ?
- 23:32:53 [Cyril]
- heycam: it doens't seem to make sense to not use some existing libraries
- 23:32:58 [Cyril]
- Cyril: performances ?
- 23:33:06 [Cyril]
- heycam: you can still write your own ?
- 23:33:14 [Cyril]
- ... Adobe is using webkit ?
- 23:33:19 [Cyril]
- cabanier: not decided yet
- 23:33:38 [Cyril]
- ... it would be silly because SVG would be a lot of work
- 23:33:54 [Cyril]
- sairus: so far the only restriction of the type of SVG content is secure animated mode
- 23:34:10 [Cyril]
- ... I have a feeling it is best to stick to that
- 23:34:21 [Cyril]
- ... not have a subset of svg defined
- 23:34:56 [Cyril]
- heycam: I would be similarly concerned with other groups subsetting SVG
- 23:35:15 [Cyril]
- shepazu: ePub, and ODF really butchered SVG
- 23:35:23 [Cyril]
- ... I wouldn't claim it to be really SVG
- 23:35:47 [Cyril]
- ... if we do things right, we will be talking to hardware manufacturers
- 23:36:29 [Cyril]
- ... we should be open to extra characterization
- 23:36:59 [Cyril]
- ... saying this element is not suitable for fonts
- 23:37:08 [Cyril]
- heycam: I'm not so concerned
- 23:37:36 [Cyril]
- ... for instance foreignObject with HTML is this allowed in fonts ?
- 23:37:40 [Cyril]
- AlexD: no
- 23:37:51 [Cyril]
- sairus: the SVG integration document should define that
- 23:38:55 [Cyril]
- heycam: we should look at the features in SVG and see if they make sense in fonts
- 23:39:45 [Cyril]
- sairus: glyph id is the only remaining extension to the SVG spec
- 23:40:01 [Cyril]
- heycam: in the Adobe proposal you propose to use the id attribute in a particular format
- 23:40:07 [Cyril]
- ... I think it's a bad idea
- 23:40:13 [Cyril]
- ... another attribute would be better
- 23:40:24 [Cyril]
- ... glyph id does not have effect on how things render
- 23:40:34 [Cyril]
- ... it's only used to locate
- 23:40:45 [Cyril]
- ... it could be added to the main SVG spec if it is a concern
- 23:41:29 [Cyril]
- sairus: OpenType and SVG processing should be separated
- 23:41:54 [Cyril]
- AlexD: using straight id, is you can use "use" elements
- 23:42:04 [Cyril]
- ... composite glyphs could use use
- 23:42:18 [Cyril]
- ... if you use glyph id you need to put both id and glyph id
- 23:42:47 [Cyril]
- sairus: the font tool will insure that hte ids are well formed
- 23:44:31 [Cyril]
- heycam: we can continue that one on the mailing list
- 23:44:35 [Cyril]
- Vlad: agree
- 23:44:47 [Cyril]
- ... having both glyph char and glyph id is confusing
- 23:44:53 [Cyril]
- heycam: that is a separate issue
- 23:45:13 [Cyril]
- Vlad: all processing is based on glyph id, definition additional things will be confusing
- 23:45:36 [Cyril]
- heycam: glyph char is unnecessary, only added as a convenience, to avoid looking at the cmap
- 23:45:48 [Cyril]
- ... I don't mind one way or the other
- 23:46:02 [Cyril]
- sairus: we can discuss color on the list too
- 23:46:19 [Cyril]
- heycam: final question, we don't want to continue with 2 documents
- 23:47:36 [Cyril]
- sairus: I do see 3 specs: defining the OpenType table (in OFF spec), SVG extensions (in SVG 2 or separate document as a 1.1 extension), Mozilla recording what they implement
- 23:48:02 [Cyril]
- heycam: in our spec, there is a description of how to process the SVG
- 23:48:14 [Cyril]
- ... where should it go ?
- 23:49:00 [Cyril]
- heycam: requirements on implementations behavior in case of error
- 23:49:26 [Cyril]
- sairus: if they are not only relevant to SVG in OpenType, they should be in the SVG spec
- 23:49:34 [Cyril]
- ... but if they are specific, they should be in OpenType
- 23:49:53 [Cyril]
- ... glyph id should be mentionned in the OpenType spec but defined in the SVG spec
- 23:50:20 [Cyril]
- heycam: maybe some wording from my spec should go into the OpenType spec maybe

- topic: next f2f
- 00:22:05 [birtles]
- heycam: csswg have settled on 5-7 June 2013
- 00:22:08 [birtles]
- ... in Tokyo
- 00:22:25 [birtles]
- ... so we want to be there 3-4, and make 5th the day for joint topics
- 00:23:08 [birtles]
- ... so that was our plan, but it was contingent on CSSWG firming up their dates
- 00:23:37 [birtles]
- Cyril: if we need an extra day we could schedule things that are not of interest to CSSWG members on Thurs
- 00:23:45 [birtles]
- krit: everything is of interest to me
- 00:23:52 [birtles]
- heycam: are 2.5 days enough?
- 00:24:04 [birtles]
- krit: should be ok
- 00:24:44 [birtles]
- Cyril: will there be a Web Animations f2f?
- 00:25:02 [birtles]
- birtles: we could have one
- 00:25:34 [birtles]
- shanestephens_: we could have one before then
- 00:26:30 [birtles]
- RESOLUTION: The next SVG F2F will be in Tokyo from 3-5 June 2013 with 5 June being a combined day with the CSSWG
- 00:28:09 [birtles]
- birtles: Mozilla Japan will host, but the day of the 5 June may be at a different location
- 00:28:24 [birtles]
- krit: what about the following f2f?
- 00:28:44 [birtles]
- AlexD: you often get less done at TPAC
- 00:29:23 [birtles]
- stakagi: note that the AC meeting is in Tokyo from 9-11 June 2013
- 00:29:49 [birtles]
- AlexD: the graphical web conference may be in the Bay Area in September
- 00:30:09 [birtles]
- birtles: where is TPAC?
- 00:30:30 [birtles]
- AlexD: Shenzhen, China
- 00:31:12 [birtles]
- heycam: do people think that June, Sept and Nov is too much?
- 00:31:15 [birtles]
- ... I feel like it is
- 00:31:39 [birtles]
- krit: what about a shared/split F2F?
- 00:32:08 [birtles]
- AlexD: I think a lot of people here will be going to the graphical web
- 00:32:14 [birtles]
- ... as opposed to TPAC
- 00:32:22 [birtles]
- heycam: I think I'd prefer to go to TPAC
- 00:32:30 [birtles]
- ... for the interaction with other groups
- 00:32:41 [birtles]
- AlexD: so maybe the graphical web should be decoupled from the wg
- 00:32:52 [birtles]
- ... and just make it more of a web conference: focussed on designers/developers
- 00:33:02 [birtles]
- ... so it might make sense to just to tpac
- 00:33:31 [birtles]
- krit: some of us will have conflicts since we need to attend css etc.
- 00:33:40 [birtles]
- cabanier: I think we can find time
- 00:34:54 [birtles]
- heycam: so is everyone ok to meet at tpac instead of the graphical web?
- 00:35:09 [birtles]
- all: yes
- 00:35:30 [birtles]
- RESOLUTION: The F2F after Tokyo will be at TPAC in Shenzhen, China
- 00:36:17 [birtles]

- topic: Proposed combined Matrix interface
- 00:37:13 [krit]
- http://www.w3.org/Graphics/SVG/WG/wiki/Proposals/Matrix
- 00:37:43 [birtles]
- krit: this is a shrunken version of the proposal from Dean
- 00:38:07 [birtles]
- ... my questions are: rotate is not correct
- 00:38:17 [birtles]
- ... Dean proposed to have rotateX, rotateY, rotateZ
- 00:38:27 [krit]
- https://svgwg.org/svg2-draft/coords.html#InterfaceSVGMatrix
- 00:38:33 [birtles]
- ... as separate methods
- 00:38:44 [birtles]
- ... but I would prefer if they were not separate methods
- 00:39:12 [birtles]
- ... the current SVG matrix rotates just around the Z matrix
- 00:39:16 [birtles]
- ... because it's only 2D
- 00:39:42 [birtles]
- ... so it just have one argument
- 00:39:58 [birtles]
- ... Dean's proposal has three arguments
- 00:40:04 [birtles]
- s/as separate methods/as separate arguments/
- 00:40:14 [birtles]
- ... the problem is how is this compatible with the current SVG matrix?
- 00:40:17 [krit]
- rotate(x,y,z)
- 00:40:31 [birtles]
- dino: SVGMatrix has just one argument (around the Z axis)
- 00:40:54 [birtles]
- ... but in this proposal has a function of the same name that takes three arguments
- 00:41:04 [birtles]
- heycam: you could overload it
- 00:41:20 [birtles]
- dino: but normally with overloading you remove arguments from the end, not add them at the beginning
- 00:41:24 [birtles]
- Cyril: can you reorder them?
- 00:41:32 [birtles]
- heycam: you don't really want z, x, y
- 00:41:50 [birtles]
- ... SVG uses just z
- 00:41:52 [birtles]
- ... in the three argument version you have x, y, z
- 00:42:18 [birtles]
- dino: the other option is to use rotateAxisAngle
- 00:42:41 [birtles]
- ... instead of rotate(angle, angle, angle)
- 00:42:52 [birtles]
- ... rotateAxisAngle(0, 1, 0, angle)
- 00:43:23 [dino]
- s/rotate(angle, angle, angle)/rotate(0, angle, 0)/
- 00:43:52 [birtles]
- shanestephens_: if you have rotate with three arguments it's x, y, z
- 00:44:01 [birtles]
- dino: I much prefer the four-argument form
- 00:44:12 [birtles]
- krit: then there's rotateFromVector(x, y)
- 00:44:44 [birtles]
- heycam: which is already on SVGMatrix
- 00:45:15 [birtles]
- krit: and it's 2d
- 00:45:29 [birtles]
- ... and it transforms the matrix from the centre into the direction of the vector
- 00:45:36 [birtles]
- heycam: it's like apply a rotation from this vector
- 00:45:58 [birtles]
- Cyril: in some 3d languages you give a vector and then you give an angle and rotate around the vector
- 00:46:23 [birtles]
- krit: so in this case you give it a point, and it rotates it there
- 00:46:32 [birtles]
- dino: I call that look-at
- 00:46:40 [birtles]
- krit: but the problem is we need to keep the SVG name
- 00:46:56 [birtles]
- cabanier: does it need to be in the merged matrix too?
- 00:47:15 [birtles]
- krit: we can make rotateFromVector work with 3D
- 00:47:21 [birtles]
- ... by adding an optional 3rd argument
- 00:47:28 [birtles]
- ... it should work
- 00:47:31 [birtles]
- ... but we can't rename it
- 00:47:45 [birtles]
- heycam: the name makes it sound like you're doing something *from* the vector
- 00:48:01 [birtles]
- Cyril: and you also want rotate around vector
- 00:48:07 [birtles]
- krit: it' not in SVG only in CSS
- 00:48:15 [birtles]
- ... I'd like to have it but it's not used a lot
- 00:48:38 [birtles]
- ... Dean's proposal is rotateAxisAngle
- 00:48:38 [birtles]
- ... maybe rotateAroundVector would make more sense?
- 00:48:44 [birtles]
- ... is that ok? instead of rotateAxisAngle?
- 00:48:50 [birtles]
- dino: that's fine with me
- 00:49:19 [birtles]
- birtles: why can't we rename again?
- 00:49:29 [birtles]
- krit: because SVGMatrix would be an alias for this
- 00:49:42 [birtles]
- heycam: not sure if it's exactly aliasing but yes, you might use this in places where an SVGMatrix is expected
- 00:50:31 [birtles]
- krit: rotate with 3 arguments is hard to use (for authors)
- 00:50:39 [birtles]
- ... so it might not make sense to have it at all
- 00:50:45 [birtles]
- ... and just keep rotate around the z axis
- 00:50:58 [birtles]
- shanestephens_: I agree the three argument version is hard to use
- 00:51:13 [birtles]
- krit: but CSS transforms supports x and y (with just one argument)
- 00:51:21 [birtles]
- ... we might want to have that as well to be compatible
- 00:51:28 [nikos1]
- nikos1 has joined #svg
- 00:51:30 [birtles]
- dino: but not on this matrix interface
- 00:51:57 [birtles]
- ... if you're diving into matrix, you're doing something complicated
- 00:52:07 [birtles]
- krit: I added skewY and skewX from SVGMatrix
- 00:52:14 [birtles]
- ... but do we want them?
- 00:52:28 [birtles]
- ... I'd rather not add them to the interface
- 00:52:34 [birtles]
- dmitry: I'd like to have rotate around a point
- 00:52:55 [birtles]
- ... like in SVG transform syntax
- 00:53:05 [birtles]
- krit: we could add that
- 00:53:11 [birtles]
- ... but then do we do the same for scale?
- 00:53:17 [birtles]
- ... scale already has 3 arguments
- 00:53:25 [birtles]
- heycam: so add another 3?
- 00:53:42 [birtles]
- dmitry: make them optional and 0 by default
- 00:53:47 [birtles]
- krit: then you have 6 arguments
- 00:53:58 [birtles]
- dmitry: it's a technical toolset
- 00:54:15 [birtles]
- ... as a developer I would really like this
- 00:54:23 [birtles]
- heycam: if we have rotate from vector, then that's another shortcut
- 00:54:32 [birtles]
- dmitry: if we have rotate from vector I really want rotate from point
- 00:55:00 [birtles]
- cabanier: maybe a new attribute on the matrix interface? transformPoint?
- 00:55:11 [birtles]
- krit: that's not what dmitry was asking for
- 00:55:15 [birtles]
- ... that's a global transform origin
- 00:55:25 [birtles]
- ... dmitry was asking for a per-operation transform origin
- 00:55:45 [birtles]
- cabanier: but maybe that's what you want? to use the same transform point?
- 00:56:20 [birtles]
- heycam: it's like how transform origin is not as useful as it could be already
- 00:56:32 [birtles]
- ... once you have a transform chain it's no longer useful
- 00:56:37 [birtles]
- ... in this case you'd have to reset the transform point
- 00:56:51 [birtles]
- ... I think it's pretty common to rotate/scale around a point
- 00:57:04 [birtles]
- dmitry: I don't mind math but not excessive math
- 00:58:19 [birtles]
- krit: do we want rotate with three additional arguments?
- 00:59:23 [birtles]
- ... scale is more complex, because you have 6 arguments
- 01:00:26 [birtles]
- birtles: is it worth considering a 3DPoint interface for the sake of code readability?
- 01:01:08 [birtles]
- krit: I don't mind adding the three arguments
- 01:01:55 [birtles]
- heycam: we already have scaleUniform and scaleNonUniform
- 01:02:01 [birtles]
- ... I think scaleUniform is more common
- 01:02:09 [birtles]
- ... for the common-case where you want to scale uniformly around a point
- 01:02:36 [birtles]
- ... we can leave scaleUniform with a single scale factor and add optional x/y/z arguments
- 01:02:56 [birtles]
- krit: I don't think that's useful to scale by the same amount in each dimension
- 01:03:08 [birtles]
- heycam: I think it's common when you want to, e.g. zoom in, but not deform the world
- 01:03:22 [birtles]
- ... when dmitry is doing a uniform scale he doesn't have to put a zero in
- 01:03:33 [birtles]
- ... or 1 in the case of scale
- 01:03:54 [birtles]
- ... does it make sense to separate uniform and non-uniform
- 01:03:55 [AlexD]
- AlexD has joined #svg
- 01:03:57 [birtles]
- cabanier: yes
- 01:04:06 [birtles]
- dmitry: I think it makes simple stuff simple and complicated stuff possible
- 01:05:28 [birtles]
- cabanier: I prefer have a transform point on the matrix, it seems more natural
- 01:05:53 [birtles]
- birtles: what about a point dictionary that you re-use
- 01:06:01 [birtles]
- ... then you can see { x: 0, etc.
- 01:06:03 [birtles]
- heycam: we can make these take different arguments
- 01:06:13 [birtles]
- ... the numbers, a dictionary, a native point etc.
- 01:07:03 [birtles]
- ... it's possible, but not necessarily what we want to do
- 01:07:08 [birtles]
- ... just the float arguments would be fine
- 01:07:22 [birtles]
- krit: the proposal from dean has radians for angles
- 01:07:35 [birtles]
- ... SVG doesn't say degrees or radians but it's assumed to be degrees
- 01:07:53 [birtles]
- ... so for backwards-compatibility I suggest degrees
- 01:08:30 [birtles]
- birtles: I agree
- 01:08:49 [birtles]
- krit: next, the SVGMatrix interface uses floats
- 01:08:55 [birtles]
- ... Dean's proposal uses doubles
- 01:08:59 [birtles]
- heycam: we should use doubles
- 01:09:13 [birtles]
- AlexD: floats are for wimps
- 01:09:28 [birtles]
- heycam: each time you return a float you have to extend it out to a double
- 01:09:56 [birtles]
- all: let's use doubles
- 01:10:09 [birtles]
- krit: next, I added flipZ next to flipX and flipY
- 01:10:14 [birtles]
- ... just to be consistent
- 01:10:19 [birtles]
- ... not sure if it's really used
- 01:10:41 [birtles]
- krit: invert(), inverts the matrix but throws an exception if it's not invertible
- 01:11:09 [birtles]
- s/invert(), /inverse(), /
- 01:11:22 [birtles]
- ... and determinant() is the same
- 01:11:54 [birtles]
- ... there are mutable and immutable functions
- 01:12:12 [birtles]
- ... mutable operations need to reproduce the functionality but with different names
- 01:12:32 [birtles]
- ... the current proposal does that by adding "By" for the mutable versions
- 01:13:23 [birtles]
- heycam: it's unfortunate that SVG uses a mix of nouns and verbs when all of them are immutable
- 01:13:33 [birtles]
- ... some of the names sound like they are modifying the object
- 01:14:37 [birtles]
- heycam: why is there no mutable flipX, flipY etc.?
- 01:15:18 [birtles]
- krit: because they're not important, what would you call them?
- 01:15:52 [birtles]
- ... I didn't find a better name but you might want to know if a matrix is 2D or not so I added is2dMatrix()
- 01:15:59 [birtles]
- heycam: what about is2D() ?
- 01:16:06 [birtles]
- ... since you're calling it in the context of a matrix
- 01:16:16 [birtles]
- dmitry: can you also add a method to split a matrix into translations etc.
- 01:16:19 [birtles]
- krit: that was proposed
- 01:16:27 [birtles]
- ... but the problem is rotation
- 01:16:50 [birtles]
- ... how do you describe the rotation?
- 01:16:55 [birtles]
- ... you could use Euler
- 01:17:00 [birtles]
- ... but then you could lose information
- 01:17:24 [birtles]
- ... so an alternative is gimbal lock
- 01:17:39 [birtles]
- ... in CSS transforms we used quarternions
- 01:17:47 [birtles]
- ... but I don't think that's really useful for authors
- 01:19:12 [birtles]
- dino: Euler angles still allow you to specify any angle in 3d space
- 01:19:31 [birtles]
- ... the reason you use quarternions is for animating between two points
- 01:19:34 [birtles]
- ... it takes the best path
- 01:19:45 [birtles]
- dmitry: is it impossible to do the decomposition of the matrix
- 01:19:51 [birtles]
- ... could we add that method to the matrix?
- 01:19:57 [birtles]
- krit: the Euler function?
- 01:20:04 [birtles]
- dino: yes we could do that
- 01:20:18 [birtles]
- heycam: is the problem that it's just one possible decomposition amongst others
- 01:20:23 [birtles]
- ... why do we use this one
- 01:20:32 [birtles]
- dino: because it's the most common one
- 01:20:53 [birtles]
- heycam: what would be return value of decompose()
- 01:21:19 [birtles]
- krit: quarternions would be four values to describe one angle
- 01:21:53 [birtles]
- heycam: if I call decompose() I would expect to get <scale amount>, <rotate amount>, <translate amount> etc., not "here is a quarternion"
- 01:21:59 [birtles]
- ... how would we return those values?
- 01:22:01 [birtles]
- ... a dictionary?
- 01:22:32 [birtles]
- ... an array of numbers where position in the array determines the meaning
- 01:23:03 [birtles]
- krit: what do we want to return? not a quarternion?
- 01:23:21 [birtles]
- ... a quarternion just represents the rotation
- 01:24:15 [birtles]
- dmitry: I want to get "the rotation is 45 degrees" etc.
- 01:26:46 [birtles]
- [discussion about quarternions, matrices, quarternions, matrices, Euler, mass confusion]
- 01:28:17 [birtles]
- dino: why are we adding this function?
- 01:28:40 [birtles]
- krit: I think you don't need to get these components
- 01:29:01 [birtles]
- heycam: I think the point of this is there are things where you do need these components
- 01:29:21 [birtles]
- shanestephens_: I just implemented CSS decomposition in javascript because it wasn't available
- 01:29:59 [birtles]
- ... to say decomposing gives you quarternions complicates the issue
- 01:30:04 [birtles]
- ... it gives you the scale etc.
- 01:30:10 [birtles]
- ... so, do we want this function?
- 01:30:14 [birtles]
- ... and what format do we want it in?
- 01:30:30 [birtles]
- ... I want this function
- 01:30:40 [birtles]
- dmitry: I and at least three others want it
- 01:31:17 [birtles]
- shanestephens_: is anyone opposed to it except for on the basis that it is a lot of work?
- 01:31:29 [birtles]
- dino: I think if we do it, it should do exactly what CSS transforms too
- 01:31:33 [birtles]
- shanestephens_: I agree
- 01:31:40 [birtles]
- dino: it's really only use for animations
- 01:32:05 [birtles]
- ... and in most cases when you write a tool to do the animations, typically the user wants to change the scale
- 01:32:26 [birtles]
- ... the only time you want to decompose the matrix
- 01:32:37 [birtles]
- ... is when you don't know the steps that built up the matrix
- 01:32:57 [birtles]
- ... typically you want to know the steps that built up the matrix and know where to apply the transformation
- 01:33:14 [birtles]
- shanestephens_: I agree, but sometimes you're forced to work with the matrix you're given
- 01:33:29 [birtles]
- ... I don't think it's a lot of work to do what CSS transforms do since it's already implemented
- 01:33:38 [birtles]
- dmitry: but often you want to work with content from another author
- 01:34:05 [birtles]
- ... for example, a clock where you know which element the hand is
- 01:34:12 [birtles]
- ... and you want to animate it, or measure the time etc.
- 01:34:23 [birtles]
- dino: the only problem there is that the decomposition will work most of the time but not all of the time
- 01:34:36 [birtles]
- ... if the matrix is unusual enough you might get an unexpected result
- 01:34:54 [birtles]
- ... you want to go back 90 degrees but you might not go the right way
- 01:35:01 [birtles]
- ... it might not solve all your problems
- 01:35:10 [birtles]
- shanestephens_: but generally you can decompose and control the decomposed result
- 01:35:22 [birtles]
- dino: I think dmitry's case where you're just changing one angle should be fine
- 01:35:27 [birtles]
- ... but once you're doing more than one thing
- 01:35:35 [birtles]
- ... you're more likely to run into something you didn't expect
- 01:35:42 [birtles]
- ... but I don't oppose putting it in
- 01:35:56 [birtles]
- ... but I want to be clear that it might not solve all cases
- 01:36:12 [birtles]
- shanestephens_: it feels like when we have these algorithms that are part of the web platform we should be exposing them to js
- 01:36:16 [birtles]
- krit: I'm ok with it
- 01:36:24 [birtles]
- ... the question is how to represent the result
- 01:36:26 [birtles]
- ... a dictionary?
- 01:36:34 [birtles]
- heycam: another option would be an array of numbers
- 01:36:45 [birtles]
- ... where the order of numbers determines the meaning
- 01:36:52 [birtles]
- ... e.g. position 0 means scaleX
- 01:36:56 [birtles]
- ... but that's a bit harder to use
- 01:37:23 [birtles]
- krit: I expect this will be used by people who know matrices

- 02:41:12 [heycam]
- Topic: Matrix continued
- 02:43:45 [heycam]
- krit: Dmitry pointed out that we also have SVGPoint in the SVG DOM
- 02:43:54 [heycam]
- … the question is, this seems to be useful in general
- 02:44:06 [heycam]
- … we've used it on some CSS properties, to convert events from one user space to another
- 02:44:21 [heycam]
- … do we want to provide a Point to other languages? So Point instead of SVGPoint? which can also be transformed...
- 02:44:33 [heycam]
- … if yes, what are the pros?
- 02:45:23 [heycam]
- … Point is interesting when you want to transform it
- 02:45:44 [heycam]
- … if you want to transform it with this 4x4 Matrix, so the point should have 4 components
- 02:45:46 [heycam]
- heycam: 3 components?
- 02:45:48 [heycam]
- … with a 1 on the end
- 02:46:12 [heycam]
- krit: if you transform a 4-valued Point with an arbitrary 4x4 matrix, all 4 of these coordinates could change
- 02:47:19 [heycam]
- heycam: I would say we don't need the fourth component for a 3D point
- 02:47:58 [nikos]
- nikos has joined #svg
- 02:48:14 [heycam]
- krit: we need the fourth component for intermediate calculations
- 02:48:21 [heycam]
- … beside that, why would you need it? can we just drop it?
- 02:48:32 [heycam]
- birtles: could you have a dictionary that has x, y, z plus whatever you call the last one?
- 02:48:33 [heycam]
- krit: w?
- 02:48:49 [heycam]
- birtles: the z defaults to 0, the w to 1; as a dictionary it wouldn't have methods, but something on the Matrix class could take a dictionary and return a dictionary
- 02:48:54 [heycam]
- … so no need to define a new Point interface
- 02:49:09 [heycam]
- … when you've got a method that takes a point in, you pass in { x: 1, y: 2 } and in 2D space you don't specify any more
- 02:49:24 [heycam]
- krit: once you set this point, can you still read back the fourth component?
- 02:49:35 [heycam]
- birtles: yes the method could stick the "w" property on there and authors could ignore it
- 02:49:45 [heycam]
- krit: I'm not in favour of a dictionary
- 02:50:00 [heycam]
- birtles: Matrix.transformPoint() could take a dictionary and return a dictionary
- 02:50:25 [heycam]
- birtles: it's convenient to use that syntax
- 02:50:37 [heycam]
- … and you can still get ".x" from the return value
- 02:51:01 [birtles]
- e.g. var ret = matrix.transformPoint({ x: 23, y: 24 })
- 02:51:12 [birtles]
- console.log(ret.x)
- 02:52:48 [heycam]
- dmitry: I like this; I don't like `new Point(23, 24)`
- 02:53:49 [heycam]
- dino: I kind of like the idea of not needing a defined type
- 02:54:08 [heycam]
- krit: SVGPoint has a transform method
- 02:54:11 [heycam]
- … what would we do with that?
- 02:54:22 [heycam]
- ed: could just leave SVGPoint around
- 02:55:51 [heycam]
- … it's used for SVGAnimatedPoints
- 02:55:55 [heycam]
- … and it's live there
- 02:56:12 [heycam]
- birtles: currentTranslate is also an SVGPoint
- 02:56:14 [heycam]
- heycam: and that's live too
- 02:56:49 [heycam]
- … so we'll add a new transform method on Matrix? taking a point?
- 02:56:51 [heycam]
- krit: yes
- 02:56:57 [heycam]
- … I think we're deciding to use a dictionary
- 02:57:09 [heycam]
- birtles: then you could also use that in some of the other methods on that interface
- 02:57:18 [heycam]
- … scale() etc., instead of taking x, y, z you could take a point
- 02:57:25 [heycam]
- … then with 2D transforms you wouldn't need to specify the last few arguments
- 02:57:33 [heycam]
- … also when you read the code it's clearer which is x, y, z
- 02:57:36 [heycam]
- krit: ok
- 02:57:52 [heycam]
- dmitry: I like it [again]
- 02:58:10 [heycam]
- krit: do we also want to have a flatten function, that converts a 3D transform to a 2D transform?
- 02:58:22 [heycam]
- birtles: what's the use case for that?
- 02:58:29 [heycam]
- krit: to use it in canvas for example
- 02:58:36 [heycam]
- … you might want a 2d version of a canvas
- 02:59:46 [heycam]
- krit: what would you do in canvas if you give a 3d matrix as the ctm for canvas?
- 02:59:54 [heycam]
- cabanier: I think canvas should ignore it
- 03:00:01 [heycam]
- … silently fail
- 03:00:36 [heycam]
- cabanier: will you be able to set a CSS Transform with this Matrix?
- 03:00:38 [heycam]
- krit: yes
- 03:00:50 [heycam]
- … in CSS OM, in the future
- 03:01:39 [heycam]
- dmitry: I like it
- 03:02:02 [heycam]
- heycam: where is this Matrix living?
- 03:02:05 [heycam]
- krit: in its own spec
- 03:02:21 [heycam]
- … I'd like to work on that spec
- 03:03:12 [heycam]
- heycam: so what about Rect?
- 03:03:15 [heycam]
- krit: I don't care about Rect
- 03:03:18 [heycam]

- http://www.w3.org/Graphics/SVG/WG/wiki/SVG2_Requirements_Commitments
- 03:31:36 [heycam]
- [79] Clarify that svgz should be as usable everywhere svg files can
- 03:32:02 [heycam]
- heycam: might mean registering a new mime type for svgz
- 03:32:12 [heycam]
- ed: not all browsers support opening svgz from the local file system
- 03:32:32 [heycam]
- heycam: is it enough to add a sentence saying svgz can be opened from the file system?
- 03:32:33 [heycam]
- ed: yes
- 03:32:54 [heycam]
- ACTION: Erik to do the "Clarify that svgz should be as usable everywhere svg files can" SVG 2 requirement.
- 03:32:55 [trackbot]
- Created ACTION-3458 - Do the "Clarify that svgz should be as usable everywhere svg files can" SVG 2 requirement. [on Erik Dahlström - due 2013-02-15].
- 03:33:03 [heycam]
- RESOLUTION: We will keep the SVG 2 "Clarify that svgz should be as usable everywhere svg files can" requirement.
- 03:33:29 [heycam]
- [80] Have a DOM method to convert a <text> element to outline path data
- 03:34:02 [heycam]
- heycam: it sounded like we went a bit off this idea of direct access to the glyph data
- 03:34:11 [heycam]
- … and instead to use the Path object to do some operations on glyph data
- 03:34:23 [heycam]
- cabanier: it's too bad there are not platform apis to consistently get outlines
- 03:34:38 [nikos]
- nikos has joined #svg
- 03:34:57 [heycam]
- RESOLUTION: We will defer the "Have a DOM method to convert a <text> element to outline path data" SVG 2 requirement to the Path object spec, but just allowing operations on glyph data and not direct access to the data.
- 03:35:03 [heycam]
- [81] Have simpler interpolation between two paths
- 03:35:20 [heycam]
- birtles: not having the same number of segments
- 03:35:52 [heycam]
- … I reckon it's really good to do, maybe not part of SVG 2?
- 03:35:59 [heycam]
- … we could look at that as part of Web Animations
- 03:36:03 [heycam]
- … and decide when to address that
- 03:36:12 [heycam]
- ACTION: Shane to investigate easier path animations.
- 03:36:12 [trackbot]
- Created ACTION-3459 - Investigate easier path animations. [on Shane Stephens - due 2013-02-15].
- 03:36:26 [heycam]
- RESOLUTION: We will defer the "Have simpler interpolation between two paths" SVG 2 requirement to Web Animations, possibly later.
- 03:36:36 [heycam]
- [82] Explicitly support Web Open Font Format (WOFF)
- 03:36:43 [heycam]
- heycam: done
- 03:36:50 [heycam]
- [83] Add snapshot time for animated documents and may specify how to get at the rendered image
- 03:37:01 [heycam]
- heycam: seems like two separate things
- 03:37:32 [silvia]
- silvia has joined #svg
- 03:37:38 [heycam]
- birtles: it doesn't help for UAs that don't do animation
- 03:38:46 [heycam]
- birtles: better to define the document in such a way that it looks the way it should without animations
- 03:39:14 [heycam]
- Cyril: are there cases where you can't create content where if the animation is not processed it wouldn't produce the same output
- 03:39:26 [heycam]
- AlexD: a cartoon.. frame 0 might be different/empty from what you want
- 03:39:37 [heycam]
- dino: maybe you don't want to show any frame of the cartoon, maybe you want something different
- 03:39:52 [heycam]
- … people embed single frames into youtube videos, it gets used as the poster
- 03:40:51 [heycam]
- RESOLUTION: We will not do the "Add snapshot time for animated documents and may specify how to get at the rendered image" SVG 2 requirement.
- 03:41:42 [heycam]
- [84] Adopt the requiredFonts attribute
- 03:42:27 [heycam]
- heycam: I don't think this is good; you need to know that specific glyphs are available
- 03:42:34 [heycam]
- RESOLUTION: We will not do the "Adopt the requiredFonts attribute" SVG 2 requirement.
- 03:42:38 [heycam]
- [85] Add the solidColor element and its properties
- 03:42:41 [heycam]
- heycam: done
- 03:42:46 [heycam]
- [86] Follow what HTML does for RDFa and microdata
- 03:43:02 [heycam]
- heycam: I'll think about that as part of global attributes
- 03:43:06 [heycam]
- [87] Add buffered-rendering
- 03:43:11 [heycam]
- ed: that is done I think
- 03:43:40 [heycam]
- [88] Have the vector-effect property
- 03:44:04 [heycam]
- ed: that is done too
- 03:44:07 [heycam]
- [89] Have the viewport-fill and viewport-fill-opacity for zoom – now should be background-color etc.
- 03:44:38 [heycam]
- Cyril: I remember we discussed that background-color is not the same thing as viewport-fill
- 03:44:50 [heycam]
- heycam: nobody is excited about doing it
- 03:44:59 [heycam]
- RESOLUTION: We will defer the "Have the viewport-fill and viewport-fill-opacity for zoom – now should be background-color etc. " SVG 2 requirement.
- 03:45:02 [heycam]
- [90] Have constrained transformations based on SVG 1.2 Tiny
- 03:45:17 [heycam]
- AlexD: I think they're useful
- 03:45:20 [heycam]
- … doesn't mean we should have them though
- 03:45:29 [heycam]
- shanestephens_: we're going to look into having some form of constrained transformation
- 03:45:35 [heycam]
- … based on some of the other requirements
- 03:46:56 [heycam]
- … I had an action to look into it
- 03:47:03 [heycam]
- … based on the results of that we can decide in June
- 03:47:08 [heycam]
- [91] Improve the bounding box text based on SVG Tiny 1.2
