Thanks, Anders!
That actually worked, the ECWs are now displayed in color.
BTW, regarding the TIFFs, I tried some program which converts them to 8 =
bit - and now they
also show up in color. So that all the problems are solved.
Thank you all, also Andrew Hallan.

I've seen this behaviour too..... I've found out that it depends on =
whether or not I have a Class object in my layers (I have one tileindex =
layer). If i remove the class object my ecw's show up in color, and if I =
add a class object they show up in black/white... (I actually use this =
as a feature, since most of my ecw images look ugly in color)....

Hope this helps.

Emne: [mapserver-users] TIFFs and ECWs rasters get a monochrome =
output - why?
Hi!
I'm using MapServer raster layers to present large background =
images.
When I got to large TIFFs (>200 MB) the server displayed an error =
message (unsupported image format or smth.).
I tried to download the GDAL support version (precompiled Win-32 =
binaries),
which also supports ECW (I have those TIFFs compressed to ECWs).
But when I fired it up - all the output turned out black-and-white, =
never mind the output format (GIF, JPG, PNG)!
Why is that happening? Is there a way to normally present large =
TIFFs or their ECW equivalents?
Thanks!
