Hello
I have a set of geotiff 8bits file.
I would like to change 1 color of the palette: puting the color 255,255,255
in the index 123 instead of color 255,0,255. While not touching anything
else.
Is there a way to do this? because I have a big set of files and I did not
find any tool which permit batch processing and keep the geo information.
Darre,
It should be quite practical to do this with a small python script, but, you
may need to use the trunk version of GDAL to get this functionality. There
was recently a bunch of work done to support more dynamic altering of tiff
colormaps that you might require.
I could provide a sample script to do this if you are interested.
Best regards,
--
