Colors not displaying in image service

[DanielSchatt]

hi all, I want to display a set of integer rasters (1 band, 32 bit) in an image service using a color map.  So I added them to a mosaic dataset (also 1 band, 32 bit) and then applied my colormap file to that mosaic dataset using the Colormap function.  The colors display properly in ArcCatalog when I preview the mosaic dataset. 

But then I generated an image service from the mosaic dataset and I just see gray in the preview of the image service.  Anybody know what the problem is and what I need to do to make this work?

Thanks!

Dan

There is a known issue with CLR files with negative values (not being used), but this does not look like the issue you are having. Can you provide some more details on the version of ArcGIS you are using. Also can you provide a sample of the CLR file you are using.

Thanks Peter.  Actually, the colors did display properly when I previewed the image service in the Javascript viewer from the REST page.   It also displayed properly when I used it in the sandbox in the Image Service sample .  So this just appears to be an ArcCatalog (and ArcMap) display issue.  I would still like to know  why it's happening as those previews can be useful.   Here's a sample of the color map file, thanks again:
