<!-- This is a complete rewrite of the original svg2gfx.xslt used for testing. --> |
| 6 |
<!-- |
| 7 |
This version supports polygons, polylines, circles, ellipses, rectangles, |
| 8 |
lines, images, text, patterns, linear gradients, radial gradients, transforms |
| 9 |
(although gradient transforms are limited), and more in addition to the |
| 10 |
paths, strokes, groups, and constant fills supported by the original. It |
| 11 |
even handles little niceties like the SVG use element. All that being said, |
| 12 |
It does not even come close to supporting all of the features found in SVG, |
| 13 |
but should hopefully be a fairly useful subset. |
| 14 |
|
| 15 |
Caveats: Completely ignores many SVG features (such as named views, filters, |
| 16 |
object bounding box in gradient transforms, etc.). Now requires properly |
| 17 |
formed SVG (that is, SVG using the appropriate SVG namespace) which most |
| 18 |
editors create by default these days anyhow (the old version required that |
| 19 |
namespaces be stripped off). Can't convert to GFX constructs that cannot |
| 20 |
be reconstructed from JSON (such as textpath or using vector fonts). |
| 21 |
Requires EXSLT for many transforms. Handles nested styles in a simple way |
| 22 |
that is usually right but sometimes wrong. |
| 23 |
