Warning: Invalid resolution 0 dpi. Using 70 instead. #7

Hi, I have encountered this message in front of the result text:

Warning: Invalid resolution 0 dpi. Using 70 instead.
Estimating resolution as 209

I guess you took the screenshot from a secondary monitor with a different DPI. I’ve no clue how to solve this. The simplest is to move your app window on the main monitor and take the screenshot from here ;)

Hi, I was using OCR workflow on my laptop, which has only one monitor though...

Should I consult with other related projects on this issue?

nicooprat commented 4 years ago

That’s weird, I never encountered this issue on my main monitor. Yes please post the solution here for others if you find it.

I have tried to import the latest OCR.workflow but Alfred reports incompatible. My Alfred version is 3.7.1.

nicooprat commented 3 years ago

Damn, I'm using Alfred 4 indeed. Could you download the previous one, and change the bash script?

export PATH=/usr/local/bin/:$PATH

screencapture -i /tmp/ocr_snapshot.png

if [{query} = ""]; then
tesseract --dpi 300 /tmp/ocr_snapshot.png  stdout 2>&1
else
tesseract --dpi 300 /tmp/ocr_snapshot.png stdout  -l {query} 2>&1
fi

Alright then, changing the script directly in Alfred Preferences does the work. Working like a charm. Thanks a million!
