The latest version works great! Thanks. For anyone wondering why the occasional landscape page is not split, you have to set auto_sense_landscape_folders = false.
Regarding the new trim_cancel option, which is awesome, if the trim amount exceeds the specified percentage, does it just trim up to the limit or does it leave the page untrimmed?
Is it possible to specify that the add_border_color option use the same color that was trimmed? If nothing was trimmed, then use a specified default border color?
I ran it against a 179 page comic and as usual, convert ate up all the virtual memory but strangely didn't use much real memory. I left it running and churning. In the morning, touching the computer made it bluescreen and reboot. After it's back, I check the comic pdf and it's perfect.

I'll have to investigate if convert has parameters to limit its memory usage. Anyway to pass in additional convert parameters during your apps operation?
Thanks!
