Hi Behnam,

I opened your tiff file succeed, I think you should want to update your unmanaged dlls. Please download this package then install it and try again:

Hi,

Please check the attached project.
the app has two buttons which one working and one not working and searching for tfw file which doesn’t exist on new tiff format.

Regards,
Ben

ps: It seems there is a problem to attach a file. so this is my code, and you can use sample file i have attached in the past:

var layer = new GdiPlusRasterLayer(@"D..\..\Sample\HY31.tif") { LowerThreshold = 0, UpperThreshold = double.MaxValue };
            var staticOverlay = new LayerOverlay()
            {
                TransitionEffect = TransitionEffect.None,
                TileType = TileType.SingleTile
            };
            staticOverlay.Layers.Add("layer", layer);
            WpfMap.Overlays.Add(staticOverlay);


            layer.Open();
            WpfMap.CurrentExtent = layer.GetBoundingBox();
            layer.Close();

            WpfMap.Refresh();

Hi Behnam,

I found the reason of your exception, that’s because your tiff file don’t have its TFW file.

If you use my code as below, that will works well:

            Map1.MapUnit = GeographyUnit.Meter;

        var layer = new GeoTiffRasterLayer(@"HY31.tif");
        var staticOverlay = new LayerOverlay()
        {
            TransitionEffect = TransitionEffect.None,
            TileType = TileType.SingleTile
        };
        staticOverlay.Layers.Add("layer", layer);
        Map1.Overlays.Add(staticOverlay);


        layer.Open();
        Map1.CurrentExtent = layer.GetBoundingBox();
        layer.Close();

        Map1.Refresh();

Hi,
Create it’s working.

It would be nice if GdiPlusRasterLayer internally manages this and support all raster files.
