Remember that as a container, pdf's can contain embedded jpg images at varying pixel densities... Christians solution would be the better solution I think. On Tue, Jul 7, 2015 at 4:36 AM Joel Rees wrote: > 2015/07/07 16:55 "Christian Mandel" : > > > > For this use case, > > Well, actually, even

For this use case, I would suggest using the pdfimages program (from xpdf I guess) (with the -j option to preserve embedded jpg) to extract the original images. The import in gimp will always "render" the pdf, what will always scale the original image, unless you hit the exact resoultion/size.

The pdf can be exported at any resolution you ask. It's the reason you can specify which density you want on import. (Imagemagick has a couple of options for handling this: http://www.imagemagick.org/discourse-server/viewtopic.php?t=8707). What happens when you set the import density higher in GIM

A small clarification. I do a lot of stuff with A5 pages. At 100 dpi an A5 image will turn out at at about 825 x 1175 pixels. I find this gives sufficient resolution for most purposes, looks good when displayed at native size on the screen, and is the appropriate size to store as a page in an
