I'm still using cocos 0.8 and I'm a little too far along in my development to update to 0.9. Instead, I've been using Joao's great AtlasTextureReader code to read the Zwoptex files (http://www.copypastecode.com/8695/).
However, I need to update the getSpriteRect function to take into account the texture offsets. My question is... what exactly is the offset value? Shouldn't it be the number of pixels trimmed from the original image size? So what exactly is the value being generated by Zwoptex?
The offset in zwoptex is the position offset of a sprite from center based on it's pixel trimming. So if you had no blank pixels on either edge of your image, the offset would be 0,0.
Another way to think about it is how many pixels do I need to offset this image to appear exactly where it was in the original image. So if you had a 480x320 image with a small dot on it, added it to your texture page and then added it to the center of your screen, the dot would appear where ever it was originally in the 480x320 image (even though it might now be a 32x32 dot on the far left of the image). The offset is storing the transform to put the dot back to where it came from.
