I'm using NSBitmapImageRep to build a new image by doing some pixel

Everything works great but with bigger sizes I'm getting a malloc
error when calling - [NSBitmapImageRep tiffRepresentation] (error
12: Can't allocate memory). I'm using this method at the end of my
processing to write the data to disk.
I guess I'm running out of memory and the allocation fails which is
rather surprising since I have plenty of disk space for virtual
memory.
How should I work around this problem?
How big are your images? You still only have 4GB of virtual address
space (and less actual and contiguous space) so if your using a
significant portion of it, then malloc()s for large chunks of memory
(like a method such as -TIFFRepresentation might require) are likely
to fail.
