Try getPixel32 which returns ARGB. Here's the link:

That's just to BitmapData. You will find the method getPixel32 there.

Thanks, but this not that I'm looking for.

getPixels - return ByteArray of BitmapData.

And getPixel32 return single pixel. So I thing I need way to convert BitmapData bytearray from argb (rgb) to bgra (bgr)

Here is solution

var bm : BitmapData = new preview();

var outBm : BitmapData = new BitmapData(bm.width,bm.height,bm.transparent);

for ( var i : int = 0 ; i < bm.width; i ++ ) {
for ( var j : int = 0 ; j < bm.height; j ++ ) {

var BGR : uint = (bm.getPixel32(i,j) & 0x000000ff) << 16 | (bm.getPixel32(i,j) & 0x0000FF00) | (bm.getPixel32(i,j) & 0x00FF0000) >> 16;
outBm.setPixel32(i,j,BGR);
}
}
