Canvas-Writer

Originally the function is made for angularjs there fore it is uses $scope, but it has been alternated as stand alone function for wider use.

The cw.js should be included, then the function is usable as follows:

<script type="text/javascript" src="cw.js"></script>
<script type="text/javascript">
<!--
    
    //Declare the settings. These settings are declared in cw.js as well, therefore they are not required if not changed.
    $scope.settings={
            fontStyle               : "normal",
            fontVariant             : "normal",
            fontWeight              : "normal",
            fontSize                : 150,
            textPositionHorizontal  : "Center", //Left,Center,Right
            textPositionVertical    : "Middle", //Bottom, Top, Middle
            textBoxShow             : true,
            fontColor               : "#ffffff",
            boxColor                : "#ffffff"
    }
    
    //The callback function gets an Image and a base64 injected into
    var callback = function(img,base64){
        //Change the source of the original elemenet
        var imgOri=document.getElementById('editedPicture');
            imgOri.src=img.src;
    }
     
    //Wait until the window loads then call the function
    window.onload = function () {
        //Call the function
        //First parameter is the id of the picture element,
        //Second parameter is the desired text on the picture. (Multi line is not supported)
        //The third parameter is a callback function. The function passed here will be called when the picture edit is done. 
        //The callback function gets an Image and a base64 injected into
        $scope.addWatermark('myPicture', "Hello World",callback);
    }
