Hi Thomas, It appeared that GIMP has invented a new format for saving the curves since the Mapverver LUT processing option was introduced in 2006 and the new format is not supported anyway. GIMP can still export the old compact format and for that the 2500 character limit may be realistic.

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 On Wed, Jan 26, 2022 at 11:11 AM Rahkonen Jukka (MML) <[email protected]<mailto:[email protected]>> wrote: Hi, I am trying to adjust satellite image colors with a GIMP curve file but trial fails because the file is too long [Wed Jan 26 12:03:52 2022].708000 msDrawRasterLayerLow(sentinel_lut): entering.

Is this a hard coded limit or can user override it somehow? The .crv file has 26000 characters and it is using ridiculous precision in entries (0.98265581597222207) but it is not easy to shrink it into 2500 characters. -Jukka Rahkonen- _______________________________________________ MapServer-users mailing list [email protected]<mailto:[email protected]> https://lists.osgeo.org/mailman/listinfo/mapserver-users
