这是我目前拥有的：
import cairoimport rsvgdef convert(data, ofile, maxwidth=0, maxheight=0): svg = rsvg.Handle(data=data) x = width = svg.props.width y = height = svg.props.height print "actual dims are " + str((width, height)) print "converting to " + str((maxwidth, maxheight)) yscale = xscale = 1 if (maxheight != 0 and width > maxwidth) or (maxheight != 0 and height > maxheight): x = maxwidth y = float(maxwidth)/float(width) * height print "first resize: " + str((x, y)) if y > maxheight: y = maxheight x = float(maxheight)/float(height) * width print "second resize: " + str((x, y)) xscale = float(x)/svg.props.width yscale = float(y)/svg.props.height surface = cairo.ImageSurface(cairo.FORMAT_ARGB32, x, y) context = cairo.Context(surface) context.scale(xscale, yscale) svg.render_cairo(context) surface.write_to_png(ofile)
