Re: [pdfmod] Feature Request: Cropping

[Gabriel Burt <gabriel burt gmail com>]

Hi John,

Thanks for the request.  We have a bug open requesting this feature already:

https://bugzilla.gnome.org/show_bug.cgi?id=595635

Please feel free to CC yourself to that bug to get e-mailed when there
are updates to it, and comment to add any missing information.

Thanks!

Gabriel
