SV: [mapserver-users] TIFFs and ECWs rasters get a monochrome output - why?

[Anders Knudstrup Hansen LE34]

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!
 
Alexander Gleyzer.
