Can the white background of the r.out.png of GRASS be changed to transparent?
I'm trying to create a transparent Polygon in ArcMap; however, it's never transparent. Here's the code I have. // Create polygon IPolygon polygon = new PolygonClass(); // create & add ...
I am trying to do this by setting up the transparency of the layer, but the markers seem unaffected by this change. Any ideas?
