Status

This work statement is under review by the CSS WG and the SVG WG. The task force is not yet active.

Objective

The objective of CSS-SVG Effects Task Force is to jointly develop features for use in both CSS and SVG, in order to provide a single underlying model for authors and implementers, and to share resources such as test suites, tutorials, and other supplementary materials.

Scope of Work

The task force combines participation from the CSS WG and the SVG WG. Accordingly, the CSS-SVG Effects Task Force operates under the CSS WG charter and the SVG WG charter.

The task force provides a forum for identification and discussion of shared features, and joint development and publication of specifications (with syntax for both CSS and SVG), including, but not limited to:

• Filters, including canned effects (high priority)
• Gradients and other paint servers (high priority)
• Transformations
  • 2D transformations (high priority)
  • 2D / pseudo-3D / non-affine transformations (medium priority)
• Animation and transitions
  • transitions (high priority)
  • Declarative animation (medium priority)
• Parameters (medium priority)
• Shared properties, such as 'image-fit' (medium priority)
• Content layout
  • Extending calc() or a related functional notation to provide general one-way constraints for element attributes and properties (medium priority)
  • Adapting CSS flexible boxes to provide positioning and sizing for SVG elements (low priority)
• Advanced text layout (along with XSL-FO WG)
  • Wrapping text to a shape (low priority)
  • Sizing shapes to fit text (low priority)
  • Vertical text (low priority)

This list is marked and loosely ordered by priority based on urgency. These priorities may change over time.

Work approach

CSS-SVG Effects Task Force communications are publicly visible. Communication mechanisms for CSS-SVG Effects Task Force include:

1. Email discussion takes place on the FX Task Force's public-fx mailing list (public-fx archive).
2. Weekly (or more frequently, as needed) teleconferences; minutes from the teleconferences are sent to the mailing list.
3. Discussion in IRC irc.w3.org:6665 channel #fx. IRC will be use for taking minutes during Task Force teleconferences andas a primary discussion channel between teleconferences.
4. Monthly (or more frequently, as needed) updates and feedback in CSS WG and SVG WG teleconferences, as appropriate. Task Force Facilitators are primarily responsible for this liaison purpose.
5. Issues are tracked in a FXTF instance of Tracker.
6. Some documentation is available from the CSS WG Wiki and the SVG WG Wiki. In addition, a separate wiki for the FXTF may be set up.
7. The first task of the FX Task Force will be to draft its initial work plan.

Task Force Facilitators MAY form subteams (composed of Task Force participants) to carry out assignments for the Task Force. The scope of these assignments will NOT exceed the scope defined herein for this Task Force. The Task Force will document the process it uses to create subteams (e.g., each subteam might have an informal "Work Statement").

Participation

Any member of either the CSS WG or the SVG WG may participate in the FXTF. It is desirable, but not necessary, that all CSS-SVG Effects Task Force participants are members of both groups and accept W3C's Patent Policy for the CSS WG and Patent Policy for the SVG WG.

Participants must actively contribute to the work of CSS-SVG Effects Task Force, including:

1. 6 to 8 hours per month of CSS-SVG Effects Task Force work;
2. Remain current on the CSS-SVG Effects Task Force mailing list and respond in a timely manner to postings;
3. Participate in CSS-SVG Effects Task Force telephone meetings, or send regrets to the CSS-SVG Effects Task Force mailing list.

Contact Doug Schepers or Chris Lilley with questions or to become a participant of CSS-SVG Effects Task Force.

Members of the public who are not covered by the W3C Patent Policy can send input to the public-fx mailing list (public-fx archive). Messages should clearly indicate the deliverable to which they are related.

Facilitation
