[tesseract-ocr] Tesseract Font Trainer

[Zhenia Krivopaltsev]

Folks,

I found training portion of tesseract quite challenging. In order to 
simplify it I have created an application to get bounding boxes for an 
arbitrary text and fonts.


In essence it is IOS FontTrainer application that  runs in XCode with IPad 
simulator.


Font trainer allows font selection, new fonts could be downloaded and added 
as well. Setting screen allows to selected desired fonts and font sizes, 
drag and drop a training text and initiate a measurement flow. The tool 
generates bunch of artifacts - with extensions - txt, tif, box, 
font_properties.

I use the tool to create a training set and found it useful. I wonder would 
it be useful for others ? In case if it is something other folks want to 
explore I will publish it.

Thanks
