I just purchased the complete Star Trek comic book collection. I wanted to crop it and put it on my nook, and your program seems the way to go!
Unfortunately, it doesn't seem to work for these files because they're secured pdfs.
DRM always screwing me up, grumble grumble....
Is there a way that I can get Briss to do its thing anyway? As is, it produces a blank pdf file after I enter the output filename. I mean, I could cheat and just print the file and send it to a "pdf printer", but that's such a hassle.
