Hi,
Is this list correct http://mapserver.org/cgi/runsub.html#runsub? It does not mention PROCESSING.
I have been thinking that it would be cool to have a WMS client which could adjust on-the-fly from the client side
- PROCESSING "BANDS=1,2,3" for making diffferent RGB versions of multi-channel images
- LUT, LUT_1, LUT_2 and LUT_3 for adjusting colours on-the-fly
- SCALE, SCALE_1, SCALE_2 and SCALE_3 for the same and especially for setting 16-bit DEMs or measument data into visible range for on-screen work.
Some clever individual could perhaps make an OpenLayers demo with cool controls like sliders and dragable LUT-curves.
By fiddling with RESAMPLE and OVERSAMPLE_RATIO it would also be possible to get images fast into screen but also with top quality if that is needed for printing.
