Autodesk Infrastructure Map Server enable to create symbols from blocks or use it from the galery (like square, circle, triangle, star, cross and X). In addition, it can load images from other formats.
When I use these images like Symbols Definitions with Transparency background in a format PNG (Portable Network Graphics) it doesn't display with transparency on the map, it has an black or white background. The question is that, what can I do to make those images keep the transparency background?
I tried to change the XML from the Symbols.Definition but for me is a little complicated.
When I look at the file from a Text symbol Definition it allows to mantain a Transparency or keep it Opaque background, but don't give me that options in the Images.
