python - how to overlay svg vector graphic over backgroud raster -


does knows how overlay svg vector graphic on backgroud raster (png) ?

preferably in python. i've tried cairo , rsvg i'm getting black bacground after converting svg png.

    img =  cairo.imagesurface(cairo.format_rgb24, width, height)      ctx = cairo.context(img)      print 'svg', tmp_svg         handler = rsvg.handle(none, str(svg_data))      handler.render_cairo(ctx)     img.write_to_png('/tmp/test.png')

after converting svg png overlay 2 png files python pil

image.blend(background, overlay, 0.5 )

maybe there simple solution overlaying directly background svg (without svg png)?

greets.

is image determined @ runtime, or beforehand? if latter, add <image> element svg points background image.
