Open GoogleCodeExporter opened 8 years ago

GoogleCodeExporter commented 8 years ago 
pypng worked with app engine image api sometime in the past ... version 67 
works. with the latest release, I'm getting the following error from this 
chunk of code.

        thumbnail = img.execute_transforms(output_encoding=images.PNG) 
//google api
        reader = png.Reader(file=StringIO.StringIO(thumbnail))
        width, height, pixel_array, metadata = reader.read()        
        writer = png.Writer(width, height, **metadata)
        output = StringIO.StringIO()
        writer.write_array(output, pixel_array)
