Question: Using objects with varying opacity/transparency on the map
Does FalconView support transparency at all? By this I mean, is it possible to create icons with 25% or 50% or 75% transparency on the FV map? Or is it possible to configure a transparency value for a layer or overlay?
I have searched on the Internet and on the FalconView site, but I have not found any indication that this is supported. However, this is a high-priority requirement for the project that I am currently working on.
Environment
| FalconView Version: | FalconView 4.0.1 |
| Interface: | |
| Language: | C# VS 2005 |

Answer
To support this, you'll need to implement the ILayerEditor3 interface and render your own icons on the map with the device context given in OnDraw(). FalconView's ILayer::AddIcon method does not support transparency.
