Use writePixels() to transfers one or more pixel components from the image pixel cache to a buffer.

You must allocate the buffer you pass to writePixels(). It cannot be NULL.

You can use whatever you want to allocate memory, new, malloc, mmap(), whatever. Its size should be 4 * width * height * 2.
