Hi

I am currently trialing your product. Everything is working, with the sole exception of an issue that occurs when attempting to export a diagram to PDF, which is a crucial requirement.

Part of the requirement is that all PNGs used in the diagram must be embedded using Base64 Encoding, rather than the source URL of the image

i.e.

group.append(new dataviz.diagram.Image({
      source: "data:image/png;base64," + BASE64_STRING,
      x: 9,
      y: 20,
      width: 38,
      height: 38
    }));

This is working nicely both on screen and when exporting the diagram to SVG. However, when exporting to PDF, the chart is rendered without the embedded images.

Any advice would be very much appreciated.

Hello Ed,

I've tried this in the Dojo and it seems to work fine. From the top of my mind I can say that this won't work in IE9 and below as it lacks support for Canvas.

Can you spot any differences with your code?
