[Image-SIG] Speed of Image.crop

[Kenji YOKOI]

Hi all,

I am trying to draw a cropped image from a larger image smoothly every 
frame. Essentially there is no problem to crop a image (image.crop) 
every frame even at 140Hz (about 7ms). But, when the cropping size 
exceeds 512x512, the cropping performance suddenly drops to 50ms or 
more. This situation was confirmed under Windows2000 and Mac OSX 10.3. 
Is this a PIL problem or a hardware problem (such as a video card or 
AGP bus speed) ?

Anyone has any idea?

Thanks in advance,
