{{x,y},{width,height} },the sprite location within the sprite-sheet as position and size values.
Most of the current texture packing tools remove transparent areas of the image before they pack it. Imagine you got a sprite with the size of 100x100, but on the left and right there are 4 columns of totally transparent pixels. The packing tool will remove these to save space, but store offset and sourceSize, so that your sprite will be 100x100 pixels in your game. Note that the offset is always relative to the center of the sprite (comparing the center of the cropped and the center of the original sprite).
Whether or not the sprite has been rotated within the sprite-sheet (if this is true, the sprite is rotated 90 degrees clockwise).
The rectangle with actual color information inside your source sprite. If you take the 100x100 image described above (with 4px transparent pixels on the left and on the right), the sourceColorRect will be
{{4,0},{92,100}} ({x,y}{width,height}).
This is the size of the original sprite (beware that some texture-packers can add padding to this if you chose to).
cocos2dx中的纹理定义格式,是以Zwoptex生成的格式为标准的. TexturePacker生成的for cocos2d plist格式与Zwoptex生成的format为2的格式相同。
