PROCESSING LUT= always shows highest value as white (mapdrawgdal.c) #2167

Reporter: hulst Date: 2007/07/20 - 22:05 Hi,

I have been trying the PROCESSING LUT_n="" directives. They work, but I found that the highest value in the raster is always colored white. That is, in my opinion, not desirable because I would be able to set my own out value there. Please refer to the attachments hs_saturated.png (white spot) and hs.png (white spot removed). The latter image was created using shp2img on the raster.map and hs.tif files after I modified mapdrawgdal.c, line 997 of revision 6358 so that it only appends a value pair 255:255 when the user did not specify a 255:x pair (see attachment). Note that I've modified my first idea stated on the mailinglist that a pair should not be appended when the user puts any value in the PROCESSING directive.

Best regards, Sander

I have applied this simplified patch in trunk as 012f27cbc7d5e53e3d0da870cb6c1428a5e16362 (r6395). It looks like an excellent adjustment!

Best regards,
