SDL_Image
I'd feel a lot more comfortable if I could see the source,
especially considering I work in both Windows and *nix.

Guys, After
my PC crashed I was forced to rebuild the pygame from sources including
SDL_Image. While doing it I noticed significant difference between my
SDL_Image loading performance and stock SDL one.
Stock: Load
100 images "data\babytux.png" took 3.25 secs ( 30.77 img/sec ) Load 100
images "data\bkgrnd2.png" took 8.08 secs ( 12.38 img/sec ) Load 100
images "data\bg.jpg" took 1.17 secs ( 85.40 img/sec ) Load 100 images
"data\cupsplash-menuad-overlay.png " took 5.72 secs ( 17.49 img/sec
) Load 100 images "data\the-cat.png" took 3.98 secs ( 25.10 img/sec
)
Mine: Load 100 images "data\babytux.png" took 2.19 secs ( 45.72
img/sec ) Load 100 images "data\bkgrnd2.png" took 5.11 secs ( 19.57
img/sec ) Load 100 images "data\bg.jpg" took 0.81 secs ( 123.00 img/sec
) Load 100 images "data\cupsplash-menuad-overlay.png" took 4.25 secs (
23.53 img/sec ) Load 100 images "data\the-cat.png" took 2.95 secs (
33.86 img/sec )
If you want to take advantage of it just take
this: http://pymedia.org/downloads/SDL_image.dll and
replace the one which comes in 1.6+ release. Speedup guaranteed
!
