I am working on PDF.js and trying to render a pdf on a webpage. I am facing misprinting issue when displaying pdf. You can see that some text is not printed properly Bad display
However, when I see the pdf in Acrobat, it is displayed perfectly. Good Display
Note* - The Pdf contains only text, no images.
I'm using very basic code to display the pdf file
var url = './highlighter_updated.pdf';
// Loaded via <script> tag, create shortcut to access PDF.js exports.
var pdfjsLib = window['pdfjs-dist/build/pdf'];
// The workerSrc property shall be specified.
pdfjsLib.GlobalWorkerOptions.workerSrc = '//mozilla.github.io/pdf.js/build/pdf.worker.js';
// Asynchronous download of PDF
var loadingTask = pdfjsLib.getDocument(url);
loadingTask.promise.then(function(pdf) {
console.log('PDF loaded');
// Fetch the first page
var pageNumber = 1;
pdf.getPage(pageNumber).then(function(page) {
console.log('Page loaded');
var scale = 1.0;
var viewport = page.getViewport({scale});
// Prepare canvas using PDF page dimensions
var canvas = document.getElementById('the-canvas');
var context = canvas.getContext('2d');
canvas.height = viewport.height;
canvas.width = viewport.width;
// Render PDF page into canvas context
var renderContext = {
canvasContext: context,
viewport: viewport
};
var renderTask = page.render(renderContext);
renderTask.promise.then(function () {
console.log('Page rendered');
});
});
}, function (reason) {
// PDF loading error
console.error(reason);
});Can anyone suggest what is wrong with this.
Thanks in advance.
