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 Steve Rahkonen Jukka <jukka.rahko...@mmmtike.fi>@lists.osgeo.org Envoyé par : mapserver-users-boun...@lists.osgeo.org 2013-09-25 11:57 A "Mapserver-Users (mapserver-users@lists.osgeo.org)" <mapserver-users@lists.osgeo.org> cc Objet [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. -Jukka Rahkonen- _______________________________________________ mapserver-users mailing list mapserver-users@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/mapserver-users
