Sorry about that I accidentally prematurely posted this, the following should 
have been in the first post:

This is my first reported issue so please excuse me if I didn't provide the 
correct format or enough information.

Have you tried Pyglet 1.2 alpha1 or the repository code?

I am currently using the latest repository code as of a few days ago.  I tried 
searching for other reports on this but I haven't seen any solutions to my 
problem.  (I have been using the following method to import images because 
Image.load and resource.image wouldn't work for various reasons.)

What steps will reproduce the problem?
1. load image using: image.codecs.pil.PILImageDecoder().decode(open("path to 
file", "rb"), "filename")
2. create sprite from image using: pyglet.sprite.Sprite(img="loaded image 
name", x=0, y=0)

Any additional info (platform/language/hardware) that may be relevant?

Platform: FreeBSD 10 64 bit, Python3.3

I fixed the error by editing line 981 of pyglet/image/__init__.py from:
    glTexSubImage2D(target, level, x, y, self.width, self.height, format, type, data)
to:
    glTexSubImage2D(target, level, int(x), int(y), self.width, self.height, format, type, data)

I am far from an experienced programmer so I don't know if this was the best 
way to fix the problem but I will leave that up to you guys.

FreeBSD is not a supported platform, we have a ticket to improve the situation, 
but it's not a priority.

See: https://code.google.com/p/pyglet/issues/detail?id=634

Alright, that's understandable.

While trying to reproduce I wrote a bugdemo:

#!/usr/bin/env python

import pyglet
from pyglet import image

window = pyglet.window.Window(640, 480)

@window.event
def on_draw():
    window.clear()
    sp.draw()

img = image.codecs.pil.PILImageDecoder().decode(open("ball.png", "rb"), 
"ball.png")
#img.anchor_x = 0.5
sp = pyglet.sprite.Sprite(img=img, x=400, y=300)

if __name__ == '__main__':
    pyglet.app.run()

It runs fine both with python 2.6.6 and 3.3.1

I think theres something more in the original situation, by example 
uncommenting the line that sets the anchor_x produces the same traceback as in 
the initial report.

Right, I figured out the problem.  I forgot that in python 3, when you divide 
two integers (such as image.width / 2), the answer may come out as a floating 
point.  So that wasn't an API issue but a coding error on my part.

Original comment by timlag1...@gmail.com on 6 Apr 2014 at 7:29

GoogleCodeExporter commented 9 years ago 
OK, anchor_x is expected to be an int:

http://pyglet.org/doc-current/api/pyglet/image/pyglet.image.AbstractImage.html#p
yglet.image.AbstractImage

The TypeError should be a clue, but I assumed it could be a platform issue.

Thanks for the report (and thanks Claudio for your help!).
