clipped image not visible on Tablet EaselJS + sourceRect used - mobile

Question

i am working on a Mobile project (iPad with iOS 8.0.2);
I want to make clipping of my immage in order to display less from it.
When displaying on PC it works perfectly well, while we test it on the tablet the clipped image is not displayed at all.
Do you have any suggestions
this.background = new createjs.Bitmap('some_image.png');
//create a clipping of drawn image!
var dims = this.background.getBounds();
this.background.sourceRect = new createjs.Rectangle(0, 15, dims.width, dims.height);
this.background.x = 248;
this.background.y = 86;
this.stage.addChild(this.background);

Answer 1

I met the same trouble like this.I have given up using Bitmap to clipping the image. I have found another solution ,here is "
easeljs splitting an image into pieces
".Good luck.

Answer 2

I am working out, the code like this:
var img, stage;
function init() {
//wait for the image to load
img = new Image();
img.onload = handleImageLoad;
img.src = "./res/image.png";
}
function handleImageLoad(evt) {
// create a new stage and point it at our canvas:
stage = new createjs.Stage("canvas");
// create a new Bitmap, and slice out one image from the sprite sheet:
var bmp = new createjs.Bitmap(evt.target).set({x:200, y:200});
bmp.sourceRect = new createjs.Rectangle(916, 101, 84, 84);
//x,y,width,height
stage.addChild(bmp);
stage.update();
}
