Posted for a colleague here:

"Can anyone supply assistance with the creation of pixel-maps on the Macintosh?

I have an array of pixel data which I would like to pass into a pixel-map data
structure and have this displayed on the mac witha colour table that is 
related to the pixel data.

If anyone has any advice/example code that they could share (either Pascal, C
or Fortran) to explain the details, this would be greatly appreciated.

The idea (I think - I can't seem to get it to work) is to create a new pixel
map with the NewCpixmap function and change the pointers in the pixel-map data
structure and colour tanble. So far I have seen a few examples of pixel-map 
creation using the copypixelmap function, but this doesn't  provide the details
of the pixel-map data structure or the passing of pixel data directly to the structure (Using the copypixelmap function most programmers seem to create
quickdraw objects using the text/rectangle ... functions, then copy an area of
the window to another window structure)"
