Hello SVG WG,
I don't remember if there is plan for this, but I wonder if it would be
possible to have the following feature in SVG2 :
An new attribute named "stroke-position" that allow author to specify the
way stroke are positioned around a shape.
This new attribute could have the following values :
- middle : the default value, it act as it is today
- inside : the rendered stroke is fully inside the shape
- outside : the rendered stroke is fully outside the shape
- <value> : the middle of the stroke is moved by the <value> to
be rendered. A positive value moved the stroke out of the shape where a
negative value move the stroke into the shape
Here are some exemples with images to show the expect rendering (the black
line is for demonstration purpose only) :
<rect width="20" height="20" stroke="red" stroke-width="5"
stroke-position="middle" />
[image: stroke-position-middle.png]
<rect width="20" height="20" stroke="red" stroke-width="5"
stroke-position="inside" />
[image: stroke-position-inside.png]
<rect width="20" height="20" stroke="red" stroke-width="5"
stroke-position="outside" />
[image: stroke-position-outside.png]
<rect width="20" height="20" stroke="red" stroke-width="5"
stroke-position="1.5" />
[image: stroke-position-positive-1.5.png]
<rect width="20" height="20" stroke="red" stroke-width="5"
stroke-position="-1.5" />
[image: stroke-position-negative-1.5.png]
I know that there is a question when the shape is not closed (where is the
inside/outside of a line ?) In this case, it's possible to relay on the
fill-rule attribute to determine this.
Thanks :)
