如何将较小的位图复制到较大的位图?

Bitmap makeBigBitmap(Bitmap srcBmps[]) {
    Bitmap wideBmp;
    Canvas wideBmpCanvas;
    Rect src, dest;

    // assume all of the src bitmaps are the same height & width
    wideBmp = Bitmap.createBitmap(srcBmps[0].getWidth() * srcBmps.length, 
        srcBmps[0].getHeight(), srcBitmaps[0].getConfig());

    wideBmpCanvas = new Canvas(wideBmp); 

    for (int i = 0; i < srcBmps.length; i++) {
         src = new Rect(0, 0, srcBmps[i].getWidth(), srcBmps[i].getHeight());
         dest = new Rect(src); 
         dest.offset(i * srcBmps[i].getWidth(), 0); 

         wideBmpCanvas.drawBitmap(srcBmps[i], src, dest, null); 
    }

    return wideBmp;
}
