I am trying to display .tif at different size modes. If I display an .tif file at fit to window, it is not as clear as Window Picture and Fax Viewer. Any suggestions?
I have messed with ......
ImageProcessing.SizeCommand
ImageProcessing.Effects.SmoothEdgesCommand
ImageProcessing.Effects.SharpenCommand
ImageProcessing.GrayscaleCommand

It doesn't seem like we can get it to a point where it will be clearly readable? It needs to be readable at different sizes. Some of the Commands takes for ever to run and that will not fly.

Any suggestions?
Thanks

If you are loading 1-bit TIFF images, try to set the RasterPaintProperties.PaintDisplayMode to RasterPaintDisplayModeFlags.ScaleToGray Or RasterPaintDisplayModeFlags.Bicubic before loading the image
+---------------+
Imports Leadtools
Imports Leadtools.Codecs
...

Private RasImage As RasterImage
Private _codecs As RasterCodecs

...
RasterCodecs.Startup()
_codecs = New RasterCodecs()

Dim PaintProp As RasterPaintProperties

PaintProp = RasterImageViewer1.PaintProperties
PaintProp.PaintDisplayMode = RasterPaintDisplayModeFlags.ScaleToGray Or RasterPaintDisplayModeFlags.Bicubic
RasterImageViewer1.PaintProperties = PaintProp

RasImage = _codecs.Load("c:\TempFiles\MULTIG4.TIF")

RasterImageViewer1.Image = RasImage
+---------------+
