[gdal-dev] help with gdal _csharp

[Amini, Manouchehr]

Dear Gdal users

I am quite new to gdal and may be my question is trivial for many of you. I am trying to use gdal_csharp to read a ascii raster file and create a super overlay on google earth. So far I am able to read the raster and change it to a picture and define a color table for it. I was wondering if there is any possibility to create a kml file using the gdal-csharp to send the picture to the google. I would like also to define transparent backgound color for the NoData regions. I used ColorEntry and defind a color (255,255,255,255). It works fine if i use ArcGis, but when I overlay the picture on google the bacground appears as white not transparent.


Thank you in advance for your help
Manouchehr
