Re: Colored Text

The 425 page file took 240 minutes to produce, or exactly 4 hours. That should work out to 36 seconds per page.

Re: Help a novice?

Welcome Scott! I'm sure you'll find lots of people here willing to help you with your project. I can't help you much with building a scanner, but since you are in the software forum, perhaps I can get things rolling on that end. What operating system do you use and what is your level of technical sk...

Re: Colored Text

Sorry to take so long to get back to you on this (pesky thing called real life kept interrupting). My end result was a djvu file weighing in at 11.9 MB. Compared to your pdf, the size is a bit bloated because each page has it's own shape dictionary, instead of using a shared dictionary across severa...

Re: I'm getting yellow tinge to background of colored text

I think things like the type of bulbs do have an effect on coloring. It might be worth it to do some searches on the hardware subforum for a long term solution. But software can come to the rescue for the images you already have. Since you're on linux, chances are you have ImageMagick installed. On ...

Re: New Project: openmargin

I really like the concept, but their site doesn't give much detail on how they plan to implement it. If they pull it off well, it could be a really neat tool to use with a book club or in a classroom setting, especially if you can make your notes private to a select group. I'm hopeful, but highly sk...

What do you mean by vectorized text? I'm really sure that tesseract doesn't work with vector graphics, only certain raster graphic formats.

Re: using scantailor and ocropus

I understand that Ocropus will do page layout
I know this is a little off-topic from the 8-bit question, but I believe tesseract-3.00 added page layout analysis (see here).

Re: Bindery

Well... djvubind needs to run tesseract twice. The first time produces just a normal plain-text file. The second time produces a files were each line is contains a character and its positional information (the corners of the box it's in). Unfortunately, the second file does not contain spaces or lin...

St. Mary Seminary up in Cleveland. What version of PyQT4 are you developing with? And python3 I assume?

Re: Bindery

@strider1551, are there any more settings that I should know about in djvubind? Sorry for not getting back to you sooner. I just returned from an 8-day silent retreat, and I have a small mountain of things to get back to speed on. No, djvubind doesn't have any settings that aren't documented (at le...
