There are some things to remember for a PDF. It is a 'finished' format meant for viewing or printing. The document size, A4 , US Letter...is a property. For printing pixels-per-inch (ppi aka dpi) has an effect but not always an easy way to determine the original size. see screenshot https://i.imgur.com/g8IP95S.jpg Scanned documents in particular can have various original ppi. A PDF document can be in forms, vectors or a bitmap ( say a scanned image) or a mix, image a bitmap + text. Gimp is not always the best tool, It might be possible to open in some other application and copy an image "as original" to Gimp . This example using LibreOffice https://i.imgur.com/a9N3Mtx.jpg but not if the document comes from a scan. Gimp is a bitmap editor. Open a PDF in Gimp and it is converted to 100% bitmap regardless of original format. Open a PDF in Gimp and the default ppi is 100. For quality, change this to 300 ppi. Only need a specific page? Then select just that page. screenshot: https://i.imgur.com/OH5Sw2s.jpg Then use the rectangular select tool, position and size over the image, Edit -> Copy for the contents. Edit -> Paste-As -> New image. Export that as required. Not the same size in pixels as an extracted image? All depends on the ppi. -- rich404 (via www.gimpusers.com/forums) _______________________________________________ gimp-user-list mailing list List address: gimp-user-list@gnome.org List membership: https://mail.gnome.org/mailman/listinfo/gimp-user-list List archives: https://mail.gnome.org/archives/gimp-user-list
