New to JS and very new to Node. Running Tesseract.js (text recognition software: http://tesseract.projectnaptha.com ) in Safari takes about 10 seconds and starts displaying progress immediately.
Node (v6.9.1) (launched from the terminal or via electron) starts the CPU up to 100% for 4 minutes 20 seconds before it starts to output to the console. Then it ends at about the same time.
What are the recommended troubleshooting steps? Is this common to Node?
The only difference that I see in the logs is "Safari", found in the eng.traineddata cache. "Clearing and disabling the cache minimally affects the time. We tried several .JPG and .PNG files (300-600kb) with the same result - but BMP (3.7MB) gave a quick response of 17 seconds - then the errors did not end. (Is this the problem of the “next tick”?)
var Tesseract = require('tesseract.js'); var image = "./images/sample.jpg"; function tesseract(){ Tesseract.recognize(image) .progress(function(message){console.log(message)}) .then(result => console.log(result.text)) } tesseract();
(editor formats output as code)
