问题
I want to load a SVG file with the Cairo library, do apply some transformations to it. Then I want to display my svg with a glTexture.
But I just find functions which create svg file and not load svg.
回答1:
Cairo itself cannot read SVG files. You need something like librsvg to render SVGs to a Cairo surface.
From a quick look at their API documentation, it looks like you need rsvg_handle_new_from_file() to load a file and something like rsvg_handle_render_cairo() or rsvg_handle_get_pixbuf() to draw the SVG to a Cairo context / to turn the SVG into a GdkPixbuf.
