New Post: Use GDAL in VB-Project

Hi
I'm also new to dotSpatial and am pretty impressed. Using v1.8 along with Tutorials 3 + 9, I can add GDAL raster to map .

For native bgd raster format I can use IRaster to access the pixels:

        Dim pRlyr As IMapRasterLayer = Map1.Layers(0)
        Dim demRaster As IRaster = pRlyr.DataSet

I've tried this for a GDAL raster:

 Dim pRlyr As MapImageLayer = DirectCast(Map1.Layers.SelectedLayer, MapImageLayer)

But pRlyr.Datasets is an IImageData and I can't figure out how to get IRaster or pixels (ie iterate through rows and columns).

Can anyone point me in the right direction?

Thanks

Tim
