Hello. I think it would be great if there is functionality to save selected pages to image. This will be very useful for websites which use PDFsharp for making PDFs online and need a preview.(like my current task  )
Perhaps there is such functionality already, if it is please let me know how it can be used? Thank you in advance and thank you for all the great job with PDFsharp, this library is awesome!

Hello, this is one of the most-wanted features, but PDFsharp cannot render PDF. See http://wikihost.org/wikis/pdfsharp/wiki/faq4265 Take a look at the PdfSharp.Ghostscript assembly. There is a function PdfToPng. You can make a function PdfToJpeg by changing the parameter Code: args.Add("-sDEVICE=png16m") (see Ghostscript documentation for details).
We at empira Software use this functionality to create page preview images and embed them into the PDF file as PNGs. So our applications can preview a page without having Adobe Reader running. Regards Stefan Lange |
