ctypes.ArgumentError from Python 3.4.2 after modifying image.anchor of an animated Gif #775

Open GoogleCodeExporter opened 8 years ago

GoogleCodeExporter commented 8 years ago 
Have you tried Pyglet 1.2 alpha1 or the repository code?

What steps will reproduce the problem?

Run the program below from 

OS X 10.10.2, Python 3.4.2
parse_version(pyglet.version)
('00000001', '00000002', '*alpha', '00000001', '*final')

Run the same code with Python 2.7.8 and there are no errors

Run the program without the section to modify the image anchor and it works in 
both Python 3 and Python 2

Program to display a sprite with an animated gif

import pyglet

window = pyglet.window.Window(800, 800) 

pyglet.resource.path = ['../resources']
pyglet.resource.reindex()

animation = pyglet.resource.animation("large_earth.gif")

anchor_x = animation.get_max_width()/2
anchor_y = animation.get_max_height()/2

for f in animation.frames:
    f.image.anchor_x = anchor_x
    f.image.anchor_y = anchor_y

world = pyglet.sprite.Sprite(img=animation, x=400, y=400) 

@window.event 

def on_draw(): 
        window.clear()
        world.draw()

if __name__ == '__main__': 

    pyglet.app.run()

Further testing I have found an animated Gif that doesn't produce the error and 
two that do:

These two cause the error
