Translucent (Semi-Transparent) Background Layers

I first load an ElevationRaster then I load a bitmap that covers the same area and the bitmap covers the ElevationRaster completely. I tried the same thing in GM9 application. If I change the order of drawing, the ElevationRaster shows but the background is covered.

I was wondering if there is a way to make a layer semi-transparent or translucent so that the two layers can be seen.

Thanks in advance.

    In the SDK you can use the GM_SetRasterDisplayOptions function to set the translucency of a layer. In Global Mapper, just open the Control Center, select the layer, press Options, then use the Translucency slider to control how see-through a layer is.

    Let me know if I can be of further assistance.
