Hello,

I'm using the imageListControl to allow user to get a quick preview the current document pages. But it seems that the quality of thumbnails is not very good as RasterImageThumbnailsBrowser. I'm using the version 17.5 C#/WPF.

So how can I importe the quality of thumbnails.

Thanks for help
Regards

Please answer the following questions:
1. Can you reproduce the same issue using our C# Raster Image list demo that ships with the SDK?
2. What are the format and BPP of the images that you use?
3. What is the build number (file version info) of Leadtools.dll that you use?
4. Can you send me a sample image that you are trying to display? Also send me a screenshot that shows how the image appears on your side?

Thanks,
Maen Badwan

When I use your sample project for RasterThumbnailBrowser, the thumbnails are significantly better than when I test with you image lsit sample project.

You can improve the quality of the images by using the following code:
==============
RenderOptions.SetBitmapScalingMode(Viewer, BitmapScalingMode. HighQuality);
==============

You need to add the code before loading any image in the ImageList control.
