<!-- 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.
|
||
|

Questions / comments / bug reports can be sent to Feneric (on Twitter, IRC,
|
||
|
|
GMail, etc.) or Eric (Saugus.net, ShellTown, etc.)
