[squeak-dev] RGB (0-255) image format?

Is there a clever and fast way to turn an array of RGB triads (each slot taking on uint8 values from 0-255) into a Form, or better yet treat it directly as a Form? If I understand ColorForm correctly, it uses a map and the image "pixels" are indexes into same. In this case, I would allocate a block of memory, hand it to a library, and it would blast the RGB values all over it. Do we have a ready way to use the result w/o having to loop over the individual values?
I am working on an interface to PLplot (http://plplot.sourceforge.net/). It is working, but so far only if I save files to disk, which I would like to not *have* to do. Sometimes (batches in particular), it makes sense to let the code that creates a graph save it, but I also like to do a lot of interactive plotting that should not have to hit the disk.
