The "on" and "off" settings only apply to bitonal (1 bit) images. There are no settings that pertain to grayscale or color images. You would have to pre-process your images with an image editor or something like GDAL Tools in order to alter their appearance.

I will be looking forward to this. I did have a question about styling a tiff: is there a way to control how the tiff is displayed color-wise in the map? When I create the data resource, there is an option to control the colors of "on" and "off" pixels. However, when I change these settings, nothing happens. I was hoping to display my image in a grey/black shading. When I look at the tiff in my layer preview and map, it has about 10+ colors. More colors is great, but how do I control their appearance? Thanks for the help. -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Zac Spitzer Sent: Wednesday, October 01, 2008 10:10 PM To: MapGuide Users Mail List Subject: Re: [mapguide-users] RE: Tiffs and MGOS 2.01 opps, I meant http://trac.osgeo.org/mapguide/wiki/MapGuideRfc51 On Thu, Oct 2, 2008 at 3:09 PM, Zac Spitzer <[EMAIL PROTECTED]> wrote: > coming very soon - http://trac.osgeo.org/mapguide/wiki/MapGuideRfc55 > > it was just committed to subversion, you should be able to compile a version > > so you got rasters with GDAL working stably? cool > > z > > On Thu, Oct 2, 2008 at 3:06 PM, Mark Pendergraft <[EMAIL PROTECTED]> wrote: >> I have upgraded to 2.02 and now I can see the tiff in my map. however, I >> can only see the tiff in my map when the coordinate system is the same as >> the coordinate system in the tiff (regardless of overrides).
