[mapserver-users] LUT file too long, what to do?

[thomas bonfort]

Hi Jukka,
Unfortunately it's hardcoded:
https://github.com/MapServer/MapServer/blob/2d73b379284aa12a2013929dfb6cdc244ae60994/mapdrawgdal.c#L1064
but it shouldn't be very difficult for you to apply a local patch fixing
that.
regards,
thomas
