Hello,

a customer of ours creates thumbnails for a presentation and the results do not look like the original slides.

We use the following code to create the thumbnail:

LoadOptions loadOptions = new LoadOptions
{
    BlobManagementOptions =
    {
        IsTemporaryFilesAllowed = true,
        PresentationLockingBehavior = PresentationLockingBehavior.KeepLocked,
        MaxBlobsBytesInMemory = 52428800,
        TempFilesRootPath = targetFolder
    }
};
using (IPresentation presentation = PresentationFactory.Instance.ReadPresentation(sourceFile, loadOptions))
{
    return presentation.Slides[0].GetThumbnail(1f, 1f);
}

The slides are attatched to this post.

with best regards,
