[mapserver-dev] Error classifying 16bit data using GDAL in MapServer - #3624

[Smith, Michael ERDC-CRREL-NH]

All (primarily Frank),

I¹m getting an assertion failed error trying to classify 16 bit data in
MapServer trunk. This is working find in 5.6.5 so its a recent change,
probably dealing with the new rendering interface work.

http://trac.osgeo.org/mapserver/ticket/3624

Doing something like this

CLASS
  NAME "0 - 1" EXPRESSION ([pixel] >= 1 AND [pixel] < 25 ) STYLE
  COLOR 227 227 227
END


Returns

mapserv57: mapdrawgdal.c:2196: msDrawRasterLayerGDAL_16BitClassification:
Assertion `rb->type == MS_BUFFER_GD' failed.
