Thanks for the reply. I had looked at these before, and then looked
again after your note, but I just don't understand how I map the climate
variable values to different colors in the palette, along the lines of:
tmax < 30 | color1
30 < tmax < 50 | color2
tmax > 50 | color3
Thanks,
Steve

Stephen,
The docs for rgb2pct.py script [1] has an example that shows how
to convert to a paletted image using hand made VRT file.
You can use the "-of PNG" option to set the destination format as
png and the -pct option with your VRT file.

Hi All,
I have 60 or so asciiGrids of climate data that I would like
to tun into PNGs, with the climate values classified by color.
I would like to script this process using Python. Is there a
way to do this with GDAL? Or if not, is there any other open
source way to do this?
Thanks,
Steve
