cd a11ycat-ocr
npm install
npm build
const { A11yCat } = require('../../dist/index')
const { resolve } = require('path')
const ocr = new A11yCat.OCR()
async function main() {
try {
// Set the path to the pdf you want to OCR
const pdfPath = resolve(process.cwd() + '/test/data/pdfs/set1/Modeling High-Frequency Limit Order Book Dynamics with Support Vector Machines.pdf')
// Set a destination directory for the pdf images
const destinationDir = resolve(process.cwd() + '/tmp')
console.log('Generating images from PDF')
// Convert a pdf to a series of images
const generatedImages = await ocr.convertPdfToImages(pdfPath, destinationDir)
console.log('Doing OCR on first page')
// Run OCR on one of the generated images
await ocr.tess(generatedImages[0])
// The OCR'd text will also be saved next to the source image
} catch (error) {
throw error
}
}
main()
Tests are located in test/spec
. Tests should use data from test/data/images
and test/data/pdfs
Because there are some large PDFs in the test dataset, this can take a very long time depending on the host computer.
