[mapserver-users] Mapserver 6 - Background color shift

[Karl Suiter]

Hi All,

  I'm hoping someone has experienced this or knows how to fix this problem.

  In currently running Mapserver 5.6 on Redhat Enterprise Linux 5
(compiled from source, no issues).  Wanting to test version 6, I
compiled the latest Mapserver 6 release on Redhat Enterprise Linus 5.
I updated the required libraries (gdal, gd, png, jpg, etc) and it did
compiled successfully.

  Running ./mapserv -v list out the usual configuration parameters.

  However, when creating a map from a mapfile using cgi-bin, the map
is drawn correctly except for the map background.  All maps are drawn
with a yellow background color.  It's as if the first decimal value is
set to zero or is missing (e.g., version 6 is rendering IMAGECOLOR as
255 255 0 instead of the 0 255 0 I specify in the mapfile)..

  I've recompiled, checked the gdal, gd and png versions, tried
different mapfiles, etc., but the color shift issue persists.

  Here are the library versions, the mapserv -v output and a mapfile snippet.

  gdal 2.0.24
  gd 1.8.0
  geos 3.2.0
  proj 4.7.0
  jpeg 8c
  png 1.5.2
  tiff 3.9.2
