svm.js

svm.js is a Javascript library to render StarView Metafiles to canvas. Tested in Chrome and Firefox.

Usage

<script src="lib/svm.js"></script>

svm.js defines one global function:

parseSVM(ArrayBuffer | DataView [, Object outArg]) -> HTMLCanvasElement

To get a canvas

var canvas = parseSVM(data); // ArrayBuffer or DataView

To get a Data URL

var url = parseSVM(data).toDataURL(); // ArrayBuffer or DataView

For more options see canvas.toDataURL() on MDN.

To get a Object URL

parseSVM(data) // ArrayBuffer or DataView
.toBlob(function(blob) {
var url = URL.createObjectURL(blob);
img.addEventListener('load', function() {
URL.revokeObjectURL(url);
});
img.src = url;
});

This function has less browser support. For more information see canvas.toBlob() on MDN.

To get the number of bytes read

var out = {};
var canvas = parseSVM(data, out);
console.log(out.bytesRead);
