How to make transparent mask for raster maps in Autodesk Infraworks?

When adding a raster map to your project in the BIM/GIS application Autodesk Infraworks, you may need to make a part of a map transparent, e.g. to underlay it and add another map layer.

After you add a new data source of the type "Raster image", right-click on the added source in the "DATA SOURCES" palette (see the map twiGIS in Terrain overlays in the example below) and choose "Configure...".

In the "Data Source Configuration" dialog then proceed to the Raster tab and click on the button ".." in the field "Color Mask". Specify, choose or pick (in the map) the color, which should be transparent in the map. The color is used without any tolerance, so this is not suitable for raster images using a lossy compression, e.g. JPG.
