Not possible AFAIK.But maybe Jan knows more. He was trying hard to become the map tranparent a few months ago for his HUD.Wolfgang

I tried this once by making a bitmap w/alpha. The main color of the bitmap acted as a "color shift" while the alpha determined the amount of transperancy. The amount of transperency also affected "color shift". In Imagetool the bitmap must be converted to 8 bit w/alpha and the in the XML syntax in the tag for the bitmap include UseTransperancy="Yes".The results were mixed as it acts as a "Color Shift" and not a color "Cover" Regards,Roman(KGRB)

Have you tried ColorLayerTerrain?nick

Hi,I was able to show a moving Next WP Ident with "star" and course-line in a transparant HUD. I couldn't reproduce the other WP's. Jan."Beatus Ille Procul Negotiis"

Sorry, ColorLayerTerrain will not work, yet ColorLayerBorders does. Strange.nick
