Scaling larger Image problem.
- by krishna
Hi,
I m developing flex application, in which I want to Draw Image from User local hard-drive to the canvas of size 640x360.
User can choose Image of bigger resolution & is scaled to Canvas size.
But if user selected images of larger resolution like 3000x2000, the scaling take lot time & freezes the application until scale done.
Is there any method to scale image faster or kind of threading can be done?
I am using matrix to scale Image as below:
var mat:Matrix = new Matrix();
var scalex:Number = canvasScreen.width/content.width;
var scaley:Number = canvasScreen.height/content.height;
mat.scale(scalex,scaley);
canvasScreen.graphics.clear();
canvasScreen.graphics.beginBitmapFill(content.bitmapData,mat);
