There are many users with problem regarding loading pygame images, be it jpeg or png.
"File is not a Windows BMP file" - not really helpful in this case :)
As per pygame documentation, to check if extended image support was enabled you should do:
>>> print(pygame.image.get_extended()) 0
Zero means it isn't, but in my case I knew it was enabled and if you don’t - it probably is.
Road to enlightenment
I’ve opened my Python3.3 installation site-packages dir (your path may vary): /usr/lib/python3.3/site-packages/pygame/
there was image.so file which is a pygame.image module inside python interpreter,
but what about other similar file - imageext.so? Both use libpng and image.so imports successfully.
So what happens if I try to import imageext?
Well, that happens:
>>> import pygame.imageext Traceback (most recent call last): File "<stdin>", line 1, in <module> ImportError: libpng15.so.15: cannot open shared object file: No such file or directory
Now, that is a core of this problem - libpng version has changed and pygame depends on older one.
How to fix
There are 3 ways i can think of:
Quick one - You could symlink expected patch to current libpng but its ugly way and may yield unpredictable results ™.
Somewhat good - You can downgrade system libpng version to match expected
Best one - Fix everything! Recompile things if your system allows it - I’m using Gentoo so it is the way I choose ;)
So, for the best way:
On any distribution - to list libs depending on missing file run:
grep -R libpng15.so.15 /usr/lib/*
Command could yield something like that:
Plik binarny /usr/lib/libSDL_image-1.2.so.0 pasuje do wzorca Plik binarny /usr/lib/libSDL_image-1.2.so.0.8.4 pasuje do wzorca Plik binarny /usr/lib/libSDL_image.so pasuje do wzorca
The sdl-image package got broken, and pygame depends on it.
Now, we have to just reinstall/update sdl-image package and everything should work. To the next libpng update :)
