[mapserver-users] RE Can variables be used in "PROCESSING"?

[Steve.Toutant at inspq.qc.ca]

I needed that for CHARTS as well
https://github.com/mapserver/mapserver/issues/4569

See the last comment: "substitutions are not yet enabled on processing 
options, but should be easy to add/implement"

Dont' know if it is plan to do it

[mapserver-users] Can variables be used in "PROCESSING"?








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.
