Hi all, I'm merging 2 raster (TIF raster) with Bentley Descartes.
I want to save the result in CIT format.
The 2 rasters have white as 1st color and black as 2nd color.
I obtain 1 raster with black as 1st color and white as 2nd color.
If I apply the invert option I obtain the result I want.
But I want to save the raster with the same option as the 2 initial rasters.
How can I do?
TIA.

If the Read Only column displayed in Raster Manager is not checked, you should be able to write to the new .cit file. When the Invert setting is used it should be able to write to the .cit and be save without further action.
I've tried what you said but Microstation doesn't save the changes in CIT file... :-(
Hi Alder,
Unfortunately the .CIT file format isn't able to save which value is white and which is black. The TIFF file format support this though.
By default the merge function in Descartes always chooses black as the background color and white as the forground color.
But you can invert the color in the TIFF file by using RastFix as follows :
- Type "mdl load rastfix" in the Key-in toolbox.
- Attach the merge operation resulting TIFF file in read/write.
- Select the TIFF file.
- In Raster Manager click on Edit->Convert Monochrome Tiff Min-is-Black to Min-is-White.

Hi Mathieu, thanks for the reply.
I converted the raster from CIT to TIF and then I followed step by step what you written but in the message center appeared the message :
"Operation failed: The raster file is monochrome but not min-is-black."
The raster hasn't been modified...
I add another thing...
When I click the 1st time on "Edit->Convert Monochrome Tiff Min-is-Black to Min-is-White" in the message center appears the message "Operation Completed Successfully"... but the raster has still black as the background color and white as the foreground color!
If I click the 2nd time on "Edit->Convert Monochrome Tiff Min-is-Black to Min-is-White" Microstation goes in error.
