yes i've been tried scaleX and scaleY. its work for me.
but i want size for specific width and height to my external image.
i've been tried setBounds(), setTransforms, and Etc but its not help much.
CreateJS does not have a way to explicitly set image width and height. If you already know the dimensions of the external image, just use some simple math to convert the desired dimensions to a scale factor. If you don't know the dimensions of the external image, you can access it from image.width and image.height. However, that will require waiting until the image is loaded.
Or, you could give up on linking the image into CreateJS's DOM and just float it directly over the canvas yourself.
