我们从Python开源项目中，提取了以下43个代码示例，用于说明如何使用PIL.ImageFile.Parser()。
def response(self, response, request, data): try: isImage = getattr(request, 'isImage') except AttributeError: isImage = False if isImage: try: #For some reason more images get parsed using the parser #rather than a file...PIL still needs some work I guess p = ImageFile.Parser() p.feed(data) im = p.close() im = im.transpose(Image.ROTATE_180) output = StringIO() im.save(output, format=self.imageType) data = output.getvalue() output.close() self.clientlog.info("Flipped image", extra=request.clientInfo) except Exception as e: self.clientlog.info("Error: {}".format(e), extra=request.clientInfo) return {'response': response, 'request': request, 'data': data}
