One of the images I'd >like to produce is a color composite. I've generated a sample image in >mcidas but I'm wondering how to do it with mcidas .k commands as the >'combine' function assembles 3 distinct frames into a single image. Do I >run imgdisp.k 3 times specifying a frame number then run a combine.k? Yes, the procedure would be identical to what you use when running a full McIDAS session. The difference would be that the environment that you run in would need to be modified to contain 3 frames. The operative part of the driver script you are using, mcdriver.sh, only creates a single frame: cd $MCDATA mcenv -f 1@900x800 -i 128 -g 32 << EOF $@ EOF This is easily modified to create 3 frames: cd $MCDATA mcenv -f 3@900x800 -i 128 -g 32 << EOF $@ EOF You would then IMGDISP (imgdisp.k) the different channels into different frames and use COMBINE (combine.k) to create the composite. >Thanks, No worries.
