Mapserver has the nice functionality for a histogram stretch of images
using the tag PROCESSING "SCALE=x,y". I would like know to predefine
TIFF images as a Virtual Format (VRT) and define the parameters for the
linear stretch in the VRT file instead of the layer definition via
Is this possible? There is the <LUT> tag but I have not understood how
to convert from the PROCESSING definition to the required values there.
What would I need for example in the LUT that corresponds to
for an image of type UInt16?
Thanks for any help
