| <!-- 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.) |
