PDF thumbnail rendering

[optima]

I need to integrate PDF thumbnail rendering in my Delphi 7 application.
I have a list of PDF files on disk, and I need to show my users small thumbnails of the first page of each PDF file (a bit like in ScanSoft PaperPort) before they decide what to do with the documents.
Does anyone know of a VCL component that can do that, or suggest possible solutions/alternatives?
