Detailed Description

A CGBitmapContext sampler initialized with an CGImage.

Method Documentation

Initialize an image sampler of a certain size with a CGImage.

If isMask is TRUE, the image will be loaded as a black and white image, if FALSE only the image alpha will be loaded.

Initialize an image sampler with an image file.

If isMask is TRUE, the image will be loaded as a black and white image, if FALSE only the image alpha will be loaded.

+ (ChipmunkImageSampler *) samplerWithImageFile:	(NSURL *)	url
isMask:	(bool)	isMask

Return an autoreleased image sampler initialized with an image file.

If isMask is TRUE, the image will be loaded as a black and white image, if FALSE only the image alpha will be loaded.
