Well, some more minor tweaks. I changed the minimum area value for the content_blocks content box selection phase (I multiplied it by 80. I doubt you'd ever get text that's completely vertical). Since my books have stuff littering the pages, I had to manually do the content box for most of them. It works pretty well now, but I'll post a patch once I truly see that it works in all cases.

That's what I'm working on. At at this stage, it will basically draw one big box which encompasses all the images (which overlaps the text, making it an image too). If the images are disjoint completely, I can make a quick fix for that. But it will be unusable if you don't want box masks around all of your picture zones, as I am completely stumped on how to integrate it into the GUI.

Has there been any more work on this? I'd like to know about it
