Utility for generating cocos2d compatible spritesheets. Currently only works on Mac OS X.
spritesheetgen INPUT_DIR OUTPUT_DIR TEXTURE_NAME
Program will traverse all image files (PNG and JPEG) in INPUT_DIR folder, place them on texture (power of 2 size, non-square) and write texture image to OUTPUT_DIR/TEXTURE_NAME.png as well as OUTPUT_DIR/TEXTURE_NAME.plist with sprite locations description.
Program will remove any transparent borders on input sprites, keeping sizes by correctly setting data in resulting plist file.
