Apply raster symbolizer on gdalimage

See original GitHub issue

Hi, I have tried to load an image manually in map control. I can now read a tiff image using gdal, here is my code

>             DotSpatial.Data.Rasters.GdalExtension.GdalImage g = new DotSpatial.Data.Rasters.GdalExtension.GdalImage(@"E:\Personal\Project\Sebal\dem\dem.tif");
> map1.MapFrame.Layers.Add(g);

well it works and loads gdal driver, But it does not show anything in map, It seems there must be some symbolizer applied on map, But I could not figure out how to do it, Can some one pleas hep me?thanks

Can you see the image if you load your tif file via Map.AddLayers()?

If this works you might be better of using Map.AddLayer(fileName) instead of trying to load it manually.

If it doesn’t work DotSpatial might have a problem loading the file for one reason or another. In this case it would be nice if you’d upload the file so we can check whether we can fix the problem.
