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. |
---|

---|
25 | GMail, etc.) or Eric (Saugus.net, ShellTown, etc.) |
