I guess that submission has been dropped due to the server switch a
month ago...
So I try resubmitting it.

regards Ralph

hi,

the attached color mapped TIFF file klink1_l.tif is incorrectly read as
GL_LUMINANCE data instead of GL_RGB data. You can easily check with
"osgViewer --image klink1_l.tif".

The bug is in ReaderWriterTIFF.cpp function simage_tiff_load, where
numComponents_ret is incorrectly set to 1 instead of 3 for color mapped
data. I included a patch against latest release version OSG 2.0
(2007/06/15).

regards Ralph
