I recieved this email today

Our viewer can improve the display of 1-bit black and white images if you enable the Scale To Gray feature. This feature is part of LEADTOOLS Document Imaging toolkits.

If you only own LEADTOOLS Raster Imaging Pro, you can work around the problem by converting the image in memory to 8-bit grayscale and using the Resample paint scaling mode.

I am using  Leadtools .NET Class Library. How exactly do I do this?
 
In the help it says i should use

public enum RasterPaintDisplayModeFlags with ScaleToGray

but how do I put this all together and where should it go?

Hello,

You can use the RasterPaintDisplayModeFlags with ScaleToGra in LEADTOOLS .Net SDK as follows:
+--------------------------+
Dim loPaintProperties As RasterPaintProperties
loPaintProperties = RasterPaintProperties.Default
loPaintProperties.PaintDisplayMode = RasterPaintDisplayModeFlags.ScaleToGray Or RasterPaintDisplayModeFlags.Bicubic

RasterImageViewer1.SizeMode = RasterViewerSizeMode.FitIfLarger
LeadImage = codecs.Load(FileName, 0, CodecsLoadByteOrder.BgrOrGray, 1, -1)
RasterImageViewer1.Image = LeadImage
+--------------------------+

Thanks,
Maen Badwan
