[Gimp-user] resolution, size when extracting from pdf vs. imagemagick

[Joel Rees <joel rees gmail com>]

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 for 36 images is not 13" x 9" at 300 dpi, unless heavily
compressed.)

ImageMagick's identify -verbose tells me the same are 1032x728 at 72 dpi.
If I use ImageMagick's convert to extract them, that's how they end up.

Anyone have an idea what's happening?
