Including fonts when converting SVG to PNG

Question

I am trying to generate some SVG and allow users of my website to download these SVGs as PNGs.
After reading this I get all my external images included in the downloaded

Answer 1

I'm able to include the font in the png itself with the following code, give it a try

var svg = document.getElementById('generated-svg');
var svgData = new XMLSerializer().serializeToString( svg );

var canvas = document.createElement("canvas");
canvas.width = 300;
canvas.height = 500;
var ctx = canvas.getContext("2d");

//display image
var img = document.createElement( "img" );
img.setAttribute( "src", "data:image/svg+xml;base64," + btoa( svgData ) );


img.onload = function() {
ctx.drawImage( img, 0, 0 );

//image link
console.log( canvas.toDataURL( "image/png" ) );


//open image 
window.location.href=canvas.toDataURL( "image/png" );
};
