I have a jpeg image when uploaded shows up a distorted blurry image. I guess something is wrong with the scaling factor, but not sure exactly.

When i try the same image in you sample demo program VBMainDemo_x64_2010, it seems to work fine.

Please find the attached file for the code and image file that I am using.

Could you please let me know what am i missing and what exactly needs to be done. Any suggestion would be greatly appreciated.

Try adding the following code:
Dim pp As Leadtools.Drawing.RasterPaintProperties = viewer.PaintProperties
pp.PaintDisplayMode = pp.PaintDisplayMode Or Drawing.RasterPaintDisplayModeFlags.Resample
viewer.PaintProperties = pp
This will fix the issue. Please note that paint properties will take effect if there is zooming on the image (this also include fitting the image to the viewer).

Can I use the same code for WPF application?
I can't find this property. Is there any other alternative?

Thanks for help.

Using "BitmapScalingMode" flags will produce a close results. Using the following line of code will produce a close image paint:
RenderOptions.SetBitmapScalingMode(Viewer, BitmapScalingMode.HighQuality);
