Drawing an image from a data URL to a HTML5 canvas
If you have a data url, you can create an image to a canvas. This can be done as shown in the following code snippet −
var myImg = new Image; myImg.src = strDataURI;
The drawImage() method draws an image, canvas, or video onto the canvas. The drawImage() method can also draw parts of an image, and/or increase/reduce the image size.
The code given below is also appropriate with the sequence - create the image, set the onload to use the new image, and then set the src −
// load image from data url
Var Obj = new Image();
Obj.onload = function() {
context.drawImage(myImg, 0, 0);
};
Obj.src = dataURL;
