问题描述
我想用Cairo库加载SVG文件，并对其进行一些转换.然后我想用glTexture显示我的svg.
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.
但是我只是找到创建svg文件而不加载svg的函数.
But I just find functions which create svg file and not load svg.
推荐答案
Cairo本身无法读取SVG文件.您需要类似 librsvg 之类的东西，才能将SVG渲染到开罗表面.
Cairo itself cannot read SVG files. You need something like librsvg to render SVGs to a Cairo surface.
快速浏览他们的 API文档，看来您需要rsvg_handle_new_from_file()加载文件，然后使用rsvg_handle_render_cairo()或rsvg_handle_get_pixbuf()之类的东西将SVG绘制到Cairo上下文中/将SVG转换为GdkPixbuf.
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.
