How to converted SVG Files into PDF in JSPDF using

Question

I struggled to converted SVG Files into PDF using JSPDF. Here i Worked in following code.

 var doc = new jsPDF();
    var test = $.get('amChart.svg', function(svgText){
    //  console.log(svgText);
        var svgAsText = new XMLSerializer().serializeToString(svgText.documentElement);
        console.log(svgAsText);
        doc.addSVG(svgAsText, 20, 20, doc.internal.pageSize.width - 20*2)
//console.log(doc);
        // Save the PDF
  doc.output('datauri');
    });

I get this script from this SO Answer.Its results only blank PDF.When i console.log(doc) before output it will shown results.But it will not results in PDF...

And I also i working in SVGELEMENTOPDF function from this GITHUB URL and I worked in this code also.

// I recommend to keep the svg visible as a preview
var svg = $('#container > svg').get(0);
// you should set the format dynamically, write [width, height] instead of 'a4'
var pdf = new jsPDF('p', 'pt', 'a4');
svgElementToPdf(svg, pdf, {
    scale: 72/96, // this is the ratio of px to pt units
    removeInvalid: true // this removes elements that could not be translated to pdf from the source svg
});
pdf.output('datauri'); // use output() to get the jsPDF buffer

But I can`t achieved it..And kindly advise me... How to solve this problem in JSPDF

Answer 1

What worked for me was to:

1. Use svgCrowbar to serialize the SVG

   var uri = svgCrowbar(eGraph);
   

2. Write the serialized SVG to a PNG dataURI using canvas

   // Create image object which will enable the graph to be saved (via canvas)
   var image = new Image();
   image.onload = function () {
       // Create canvas 
       var canvas = document.createElement('canvas');
       canvas.width = image.width;
       canvas.height = image.height;
       var context = canvas.getContext('2d');
       context.drawImage(image, 0, 0);
   
       // Save DataURI for later use
       window.sitescriptdata.dataURI[id] = canvas.toDataURL('image/png');
       window.sitescriptdata.numDataURIsLoaded++;        
   
       ...
   
   };
   image.src = uri;
   

3. Use jsPDF.addImage() to embed that PNG into the PDF

Using this method I was able to embed multiple dynamically generated SVGs into a single PDF. I'm not 100% happy with the outcome as the images on the PDF look distorted, but it might be that I need to do more tweaking of the jsPDF settings to get everything to look crisp.
