[Image-SIG] Example Code for Displaying Pictures--I'm Stumped

[Bill Janssen]

Another good option is pyglet.  I use it for converting video to streams
of PIL images.

Here's the code for turning a pyglet image into a PIL image:

    def pyglet_to_pil_image (pyglet_image):
        image = pyglet_image.get_image_data()
        format = image.format
        if format != 'RGB':
            # Only save in RGB or RGBA formats.
            format = 'RGBA'
        pitch = -(image.width * len(format))

        # Note: Don't try and use frombuffer(..); different versions of
        # PIL will orient the image differently.
        pil_image = Image.fromstring(
            format, (image.width, image.height), image.get_data(format, pitch))
        # need to flip the image to accommodate Pyglet's transform space
        pil_image = pil_image.transpose(Image.FLIP_TOP_BOTTOM)
        return pil_image

This code is part of extensions/video.py, part of the UpLib source code
at http://uplib.parc.com/.
