Looking at other posts for this could not find an adequate solution that for my needs. Trying to just get the first page of a pdf document as a thumbnail. This is to be run as a server application so would not want to write out a pdf document to file to then call a third application that reads the pdf to generate the image on disk.

doc = new PDFdocument("some.pdf");
page = doc.page(1);
Image image = page.image;

Thanks.
