glsvg

A python library for parsing and displaying SVG files using opengl, with a focus on being usable for games.

---

Usage

    import glsvg

    # initialize opengl context
    # ...

    # load svg file
    svg_doc = glsvg.SVGDoc(filename)

    # draw svg file
    svg_doc.draw(x,y)

---

Status

Requires:

• PyOpenGL

Supported game libraries:

• PyGame
• Pyglet

Supported SVG features:

• All SVG path commands (arc/curves/lines/etc.)
• Basic SVG shapes (rectangle, ellipse)
• Per-Pixel Linear and Radial Gradients
• Parsable color names
• Variable line widths and miter/bevel joints

SVG Features In Progress:

• SVG patterns
• SVG effects (Drop shadow, blur, etc.)
• More sophisticated line effects (patterns, arc joints, etc.)

Likely to be not supported:

• Animation
• Text (this would be likely to require too many extra dependencies for fonts, but an easy workaround is to convert text objects to paths in your editor, ie Inkscape or Illustrator)
• CSS based style tags

glsvg's Issues

Please support retained mode to allow OpenGL ES compatibility

Awesome to see squirtle getting some love and attention!

I'd like to request that you implement the drawing using retained mode instead of immediate mode; this would allow the library to be used with OpenGL ES applications such as those running on Android / iOS and other OpenGL ES platforms.

How to render to a texture or pyglet sprite

Hi,
Any idea how to render to a pyglet sprite?

S

How do I draw an SVGDoc multiple times?

Only the last .draw call appears to have any effect. From some of the methods/attributes on SVGDoc, I was hoping Sprite + Batch would work; but it doesn't.

(If you explain me how to do this, I'll gladly document it for you.)

Documentation on pypi is wrong

I tried the example on pypi and got this:

Traceback (most recent call last):
File "go2.py", line 8, in
svg_doc = glsvg.SVG(filename)
AttributeError: 'module' object has no attribute 'SVG'

TypeError: float() argument must be a string or a number

This smiley svg on wikipedia causes an error
