Question

Examples on the Internet claim that simply setting scaleX=”-1″ will flip an image in Flex.

But when I do this, the image doesn’t seem to render at all.

What’s going on? How can I troubleshoot the issue? I’ve tried placing it in a Canvas and a VBox, same result.
(Note – the image is rather large, 5600×2100 or so.)

Answer 1

Not sure why scaleX isn’t working, but I came up with a solution:

        var flipVerticalMatrix:Matrix = new Matrix();
        flipVerticalMatrix.scale(1, -1);
        flipVerticalMatrix.translate(0, bm.height);

        bitmap = new Bitmap(new BitmapData(bm.width, bm.height, false, 0x00AA00));
        bitmap.bitmapData.draw(bm, flipVerticalMatrix);

Would still be interested in any info as to why scaleX didn’t work.
