Gif dithering

Hi

I am experiencing dithering when converting vsd to GIF, this is not present when save the vsd as gif from Visio.

This is the code used to generate the output:

   var d = new Diagram("src.vsd");
   var so = new ImageSaveOptions(SaveFileFormat.GIF);
                so.CompositingQuality = CompositingQuality.HighQuality;
                so.InterpolationMode = InterpolationMode.HighQualityBicubic;
                so.Resolution = 96;
                d.Save(outputGif, so);

visio-gif-dithering.zip (524.5 KB) contains: src.vsd, aspose.gif, visio.gif - output gif is named according to output generator.
