PDF.JS Download behavior

[OwNaGe]

I was wondering how the pdf.js library handles the download of a pdf page. If I execute this code:\[code\]var test_pdf = "documents/pdf"; PDFJS.getDocument(test_pdf).then(function(pdf) { // Using promise to fetch the page pdf.getPage(1).then(function(page) { var scale = 1; var viewport = page.getViewport(scale); var realwidth = viewport.width; // Scale all documents to a width of 520px var newscale = 520/realwidth; var viewport = page.getViewport(newscale); // // Prepare canvas using PDF page dimensions // var canvas = document.getElementById('the-canvas{{slide.page}}'); 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 }; page.render(renderContext); });\[/code\]So here I only display the first page of the PDF but I think the client downloads the whole pdf right?If this is right, does anybody maybe if it is possible to only download a given page off the pdf file?
