How can i custom tesseract parameters?

[hoolyfook]

default params not working on my pdf, so i need to custom it
tesseract page_1.png page_1 -l script/Vietnamese+vie --oem 3 --psm 6 -c preserve_interword_spaces=1

You can create a text file e.g. named my.cfg containing

preserve_interword_spaces=1

then use

ocrmypdf --tesseract-config my.cfg --tesseract-oem 3 --tessearct-psm 6 --lang script/Vietnamese --lang vie in.pdf out.pdf
