Direct file input
Created by: ventsyv
Both tesseract and cuneiform allow the user to pass in a file name as input. I would like to add a function that will take a file name directly and pass it to the OCR engine, rather than having to create a temporary input file. Since I was not able to replace the file IO with memory pipe for tesseract, having a function like that will speed things up since it will eliminate the unnecessary file IO.
