CGImage does not provide an efficient way to update , but maybe
CGImage is not what you want.
Where your image come from, why do you need a CGImageRef and what are
you trying to do with it ?

I'm modifying frequently the pixels of the images, the way I found is
creating a copy of the data
(CGDataProviderCopyData(CGImageGetDataProvider(image));) modify the
pixels and then create a new one. I'm facing performance issues and I
fear that all this allocating and deallocating is not helping. Is
there a way I could have access and modify the pixels of a CGImage
without copying them?
Thanks, chr
