I am developing a Delphi documents management application, so somehow I am giving the user some functionality similar to windows explorer.
I would like to know if there is a way to get the preview used by windows explorer. For example windows explorer creates a small thumbnail for a pdf document for example, and displays it when the user chooses to view “big icons”. Is there a way to retrieve that preview?
MyTImage := GiveMePreviewForFile('C:\Test\File.pdf');
@user193655, using the IExtractImage interface is the way to go,
this interface exposes methods that request a thumbnail image from a Shell folderyou can find a very complete sample in this site and the source code is here.
