Canvas element context putImageData issue

[cmessineo]

This code worked in Qt 5.3.2, but since I upgraded to Qt 5.5.1 it doesn't work anymore.
I'm guessing putImageData has changed but I can't find any examples of it's use.

Any ideas?
Thanks

@
Canvas{
width: 300
height: 300

    onPaint:{
        var ctx = getContext("2d");
        ctx.fillStyle = "red";
        ctx.fillRect(10,10, 50, 50);
        var copy = ctx.getImageData(10,10,50,50);
        ctx.putImageData(copy, 20, 20);
    }

}

@cmessineo It seems it works using Qt5.6 on Ubuntu 14.04. It shows a red rectangle if thats is what you are expecting.

I would expect to see two red rectangles. One overlapping the one at the 10, 10 position.

Well apparently you need to use:

ctx.drawImage(copy, 20, 20);

to make it work.
