[mapguide-users] RE: Tiffs and MGOS 2.01

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.

Thanks.  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.
