I have a pdf of scanned images, theoretically jpeg images, and the gimp
will offer me a selection dialog, from which it will import them
individually as 1304x932 at 100 px/in. (This is odd, because I selected
300dpi at scan time, so the images should be 3 times that pixel density.
But, then, 22Mb f
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
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.

For some reason, I was expecting that dialog to offer the actual resolution
of the encapsulated jpeg image as a default. Would be nice to have a

Well, actually, even IM's default 72 px/in would have done my present job.

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.

I know this isn't specifically GIMP related, but I figured there might be
some photographers on the list that would find some interest in this.
Over on PIXLS.US, the creator of a new image processing project, PhotoFlow,
has just finished writing a nice tutorial on creating an exposure blended
