Extend

  • v1.0.9 and above break pagerender callback changelog
  • If you need another format like json, you can change page render behaviour with a callback
  • Check out https://mozilla.github.io/pdf.js/
// default render callback
function render_page(pageData) {
    //check documents https://mozilla.github.io/pdf.js/
    let render_options = {
        //replaces all occurrences of whitespace with standard spaces (0x20). The default value is `false`.
        normalizeWhitespace: false,
        //do not attempt to combine same line TextItem's. The default value is `false`.
        disableCombineTextItems: false
    }

    return pageData.getTextContent(render_options)
    .then(function(textContent) {
        let lastY, text = '';
        for (let item of textContent.items) {
            if (lastY == item.transform[5] || !lastY){
                text += item.str;
            }  
            else{
                text += '\n' + item.str;
            }    
            lastY = item.transform[5];
        }
        return text;
    });
}

let options = {
    pagerender: render_page
}

let dataBuffer = fs.readFileSync('path to PDF file...');

pdf(dataBuffer,options).then(function(data) {
    //use new format
});
