One choice is to dump out hocr instead of just UTF8 text. So do: tesseract test.tif test hocr where hocr is the name of the built-in config file that is in tessdata/configs. This will generate test.html instead of test.txt. See [1] for a bit more info on hOCR. If you aren't afraid of doing some programming, look at the code for TessBaseAPI::GetHOCRText [2]. It uses res_it->IsAtBeginningOf(RIL_PARA) to figure out where each paragraph begins. > On a somewhat related note, > is there any way to control Tesseract's command line behavior at all? > I see that it accepts a config file as a command-line option, but I'm > having no luck finding documentation on what options are available or > what they mean -- the provided examples don't actually seem to work, > and even searching the code hasn't given me anything resembling a list > of valid options. > > Any help or pointers in the right direction would be greatly > appreciated! > > thanks, > Demian AFAIK there aren't any good docs on config files yet (I'm working on that). But look in tessdata/configs & tessdata/tessconfigs for example config files. To get a list of possible config file parameters, see this thread [3], in particular this message by me [4].
