Flex converts an image into a binary image and then converts it to BMP.

As package:

Package com. PAG
{
Import flash. display. Bitmap;
Import flash. display. bitmapdata;
Import flash. Geom. rectangle;
Import flash. utils. bytearray;
Import MX. Controls. Alert;
 
Public class bitmapbytes
{
Public Function bitmapbytes ()
{
Super ();
}

Public static function bitmapdatatobytearray (target: Bitmap): bytearray {
VaR imagewidth: uint = target. width;
VaR imageheigh: uint = target. height;
VaR srcbmp: bitmapdata = new bitmapdata (imagewidth, imageheigh );
Srcbmp. Draw (target );
VaR pixels: bytearray = srcbmp. getpixels (New rectangle (0, 0, imagewidth, imageheigh ));
Pixels. writeshort (imageheigh );
Pixels. writeshort (imagewidth );
Alert. Show ("" + pixels );
Return pixels;
}

Public static function bytearraytobitmap (byarr: bytearray): bitmap {
If (byarr = NULL)
Return NULL;
VaR BMI: bytearray = byarr;
>;
VaR imagewidth: Int = BMI. readshort ();
Bone mineral density. Position = Bone Mineral Density. Length-4;
VaR imageheight: Int = BMI. readshort ();
VaR copybmp: bitmapdata = new bitmapdata (imagewidth, imageheight, true );
BMI. Position = 0;
For (var I: uint = 0; I <imageheight; I ++ ){
For (var j: uint = 0; j <imagewidth; j ++ ){
Copybmp. setpixel (J, I, BMI. readunsignedint ());
}
}
VaR BMP: bitmap = new Bitmap (copybmp );
Return BMP;
}

}
}
