    找个好久， 做个记录  8-)
    1. #!/usr/bin/env python
    2. # -*- coding: utf-8 -*-
    4. import cairo
    5. import math
    7. surface = cairo.ImageSurface.create_from_png("touxiang.png")
    8. w = surface.get_width()
    9. h = surface.get_height()
    11. surface2 = cairo.ImageSurface(cairo.FORMAT_ARGB32, h, w)
    13. cr = cairo.Context(surface2)
    14. cr.translate(w * 0.5, h * 0.5)
    15. cr.rotate(math.pi * 2 / 3)
    16. cr.translate(-w * 0.5, -h * 0.5)
    17. cr.set_source_surface(surface, 0, 0)
    18. cr.set_operator(cairo.OPERATOR_SOURCE)
    19. cr.paint()
    21. surface2.write_to_png("result.png")
    Copy the Code
