Modify Thumbnail Properties

A thumbnail's properties can be modified, to include a different item descriptor (SetItemDescriptor) or user information (SetItemUserTag). 

Modify the Thumbnail Image

If the thumbnail image was loaded from file, the thumbnail image can be replaced by a different page in the file using the SetItemPage method. This method generates the thumbnail from the selected page in the file, then replaces the existing thumbnail with the new image.

If the thumbnail image was loaded from file, the thumbnail image can be replaced by a page in a different file using the SetItemFilename method. This method generates the thumbnail from the new file (page number remains unchanged), then replaces the existing thumbnail with the new image.

If the thumbnail represents a page in a CAD file, the thumbnail image can be replaced by a different layout in the file using the SetItemCadLayoutNumber method.
