I have a tool using HTML 2 Canvas which also utilizes CSS "zoom" to allow for larger areas to be drawn/printed - however for some reason the capture area of HTML 2 Canvas does not change when zooming out in the div.

You can test this for yourself here: http://www.thermmark.co.uk/planner (Zoom out 1-2 levels and draw a grid in the main area - the capture area for HTML 2 Canvas keeps to a very small area

Is there a possible fix/change for this?

I have this issue too.

I was wondering about whether it should remove the zoom property on the element first, then scale it down the appropriate amount within the canvas. Potentially this would make a good option as you may want the canvas image to be the same size of the rendered 'zoomed' version of the content.

Certain elements seem to be totally missed out of an element with the zoom property.
