We have some symbol bitmaps we use for point data that have white backgrounds. In our desktop product using ActualMap we set the transparent color for the symbol to white and the bitmaps show as intended on the map.
We are currently working on a web version of the same product and the same bitmaps are not working. The point data is coming from the same shape files, the symbology data is exactly the same, the Symbol.TransparentColor is set to 255,255,255 (ARGB) but the backgrounds show up on my map. I have also tried changing a bitmap to use the more standard pink background (255,0,220) where I want it to be transparent but it did not help.
Would I be better off converting the symbol bitmaps to pngs with proper transparency?
Any suggestions how to solve this issue?
