Heatmap / Imageoverlay

Hi,
I am planing to draw several Heatmap Images from an datasource.
Thatfor I have an
List<DataRow[]> Datablock;
Now I am at the point to draw the Heatmap-Image and wonderig now about the following:
- My only oportunity to draw the Heatmap-Image is to draw an Image with an fixed size.
- I am thinking to draw allways Heatmaprasters of the same size (Say 0.1°)
- Thouse Heatmap-Imagecollection I want to add with the GMap.NET - GroundOverlay to the GMap.
- When I draw the Heatmap I have to fix it with an fixed Pixel-Size (Say 200x200px)
- I have the Geographic Bounds of the Heatmap
Question:
Does the GroundOverlay Method now scale the Heatmap-Image to fit into the Bounds? Also when I zoom-in?
If yes then the Image will be scaled?
If the Image I add with GroundOverlay is an transparent PNG-24 Image. WIll the Image apear on the GMap also with transparency?
Regards,
Mansur
