[Juanjo Serrano Lloria]

Hi,
Did you try activating the makebox configuration?

Example in command mode:
tesseract isis_0153.png isis_0153 makebox hocr

[tesseract-ocr] Re: Is it possible to pass a numpy array to Tesseract, instead of saving it to the disk.

[Juanjo Serrano Lloria]

Perhaps a solution is to create a memory filesystem.

Re: [tesseract-ocr] Re: Parameters to increase tolerance of whitespace between characters?

Same problem in tesseract 4.1.0. Removing whitespaces. I've tried with a
