I do something similar in serveral image processing programs.
I create a GL Canvas and use OpenGL or MesaGL (the freely available X
based OpenGL clone) to just do a glDrawPixels() into the canvas.
Works neat and fast.
You can get Mesa at
ftp://iris.ssec.wisc.edu/pub/Mesa
The latest official version at this writing is 2.2. A Beta version of
it is available in
ftp://iris.ssec.wisc.edu/tmp/Mesa-2.3beta2.tar.gz
It works really well.
The glDrawPixels() function accepts all sorts of different data types,
including unsigned short. You can do zooms and, with some work, pans
of pixel data quite easily.
