Load image of size greater than 2880 in Bitmap

I am using bitmap to load the image, if the image size is more than 2880 h/w I am getting an error.

BitmapData src = new BitmapData(canvasToPrint.width,canvasToPrint.height)(canvasToPrint.width, canvasToPrint.height);
src.draw(_designArea);  // -- encode the jpg        
var quality:int = 115; 
var jpg:JPEGEncoder = new JPEGEncoder(quality);                 
var byteArray:ByteArray = jpg.encode(src); 

if canvasToPrint.width > 2880 or canvasToPrint.width > 2880 I will get below error at li开发者_开发知识库ne 1 Error : invalid Bitmap

To over come the above issue I have used bitmapdataunlimited class, as mentioned in the below link.

But it only works fine for 4096 pixel of height and width, guide me if any alternative solution is there to create huge bitmap.

If makes a difference which FlashPlayer you are targetting:

versions VS maximum bitmapsize

flashplayer -9 : 2880x2880 px
flashplayer 10 : 4096x4096 px
flashplayer 11 : unlimited
