Hi,

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.

Thanks
Divya

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).

Hi,

Can I use the same code for WPF application?

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);
==============

Thanks,
