UIImage stretch only a portion

Question

So, lets say i have this sprite:

mbm
bcb
mbm

where each letter is a portion. (m: margin; b: border, c:center)

and I want a class that is able to repeat the b's and c as long as it needs to complete the view so i get something like this:

mbbbbbbbbbbbbbm
bcccccccccccccb
bcccccccccccccb
bcccccccccccccb
mbbbbbbbbbbbbbm

Is there something that can do this already? If it doesn't exist, any ideas on how to implement it?

Answer 1

Could you not achieve this with this method ?

-(UIImage *)stretchableImageWithLeftCapWidth:(NSInteger)leftCapWidth topCapHeight:(NSInteger)topCapHeight

(see Apple UIImage Class Reference )
