The putImageData function

Share RGraph:   To help my Google visibility (it can't get much worse!), if you like and use RGraph I'd appreciate it if you could link to me

The putImageData function allows you you add an ImageData object that you have been manipulating back on to the canvas. You pass the function the ImageDataObject and the X/Y coordinates of where you want it placed. Optionally you can specify which portion of the ImageData object to use.

Arguments to the function

An example

<script>
    window.onload = function ()
    {
        var canvas = document.getElementById('cvs');
        var context = canvas.getContext('2d');
        
        // Copies an ImageData object on to the canvas
        context.putImageData(imgData);
    }
</script>
