CCSprite Wrap Image?

CCSprite Wrap Image?
0.0 0



I have subclassed CCSprite to detect touch.
I have a image that is just 225 x 225.
The reason I subclassed CCSprite is because I thought by doing so the touch location of 0,0 will actually start from the 0,0 of the actual image.
Now I find out that there is a gap in both the x and y axis from the edge of the screen to the actual image.
I was wondering if it is possible to tell the CCSprite to wrap its size based on the image’s size so that a touch on 0,0 will actually be the 0,0 of the image.
and the touch on the gap will not be detected by this CCSprite

Is this possible?

Thank you
