You can call Lept4J's *LeptUtils* 

.*removeLines* 

(*Pix* 

 pixs).

Charles Weld's Tesseract .Net implements Leptonica's RemoveLines for 
grayscale in Pix.cs.

[tesseract-ocr] Re: Not getting any result with Tesseract-ocr v3.05.01 on Windows

[Ruben Gaspar]

Just to add that the pdf's I am trying to process are mostly handwritten 
documents. Is it possible for tesseract-ocr to deal with handwritten docs?

Thank you,
Ruben

[tesseract-ocr] New Fonts Training

[joshyjosh . martinez]

Hi everyone,

All the tutorials I have been through just mention "creating a new font 
file and then training Tesseract" so how do I create font files for 
training?

For example, if I have a couple of price labels that I wanna OCR their 
characters and numbers, how do I put together a font file for them, in 
order to train Tesseract?

Thanks in advance,
