• Converting captured signature to PNG

    By Brian M Moore 3 years ago

    Needing to make an image of this, I found a way. Here is my blog post on it: http://dominoherald.blogspot.com/2016/06/html5-canvas-to-png-via-rpc.html

    in short, you can use the toDataURL method to get a base64 of the signature:

    var canvas = document.getElementById(“view:id1:id2:canvasArea”);
    var str = canvas.toDataURL(“image/png”);

    then take that string and convert it to a file (note there is a 'header' in the returned string that needs to be removed).

    A full XPage and the SSJS function I used it on my blog at the link above.

    Cheers,
    Brian
