<!-- This is a complete rewrite of the original svg2gfx.xslt used for testing. --> |
|
<!-- |
|
This version supports polygons, polylines, circles, ellipses, rectangles, |
|
lines, images, text, patterns, linear gradients, radial gradients, transforms |
|
(although gradient transforms are limited), and more in addition to the |
|
paths, strokes, groups, and constant fills supported by the original. It |
|
even handles little niceties like the SVG use element. All that being said, |
|
It does not even come close to supporting all of the features found in SVG, |
|
but should hopefully be a fairly useful subset. |
|
|
|
Caveats: Completely ignores many SVG features (such as named views, filters, |
|
object bounding box in gradient transforms, etc.). Now requires properly |
|
formed SVG (that is, SVG using the appropriate SVG namespace) which most |
|
editors create by default these days anyhow (the old version required that |
|
namespaces be stripped off). Can't convert to GFX constructs that cannot |
|
be reconstructed from JSON (such as textpath or using vector fonts). |
|
Requires EXSLT for many transforms. Handles nested styles in a simple way |
|
that is usually right but sometimes wrong. |
|
