我们从Python开源项目中，提取了以下8个代码示例，用于说明如何使用Image.ROTATE_180。
def flip_image(self, imagein): outstr = "" outfile = StringIO.StringIO(outstr) img = Image.open(StringIO.StringIO(imagein)) out = img.transpose(Image.ROTATE_180) out.save(outfile, img.format) return outfile.getvalue()

If given, this should # be one of Image.FLIP_LEFT_RIGHT, Image.FLIP_TOP_BOTTOM, # Image.ROTATE_90, Image.ROTATE_180, or Image.ROTATE_270.
