| 5 | <!-- 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 | |||
| 24 | Questions / comments / bug reports can be sent to Feneric (on Twitter, IRC, |
||
| 25 | GMail, etc.) or Eric (Saugus.net, ShellTown, etc.) |
