Add function to flip image horizontally/vertically

[tulang3587]

For the stickers, wouldn't an image flip functionality be good?

if you have enabled setPinchTextScalable(true) than you can rotate the sticker using pinch i.e rotate using two fingers

Sorry, I meant flipping as in mirroring the image would be a good addition.

Any general use case for mirroring sticker ?

[tulang3587]

I think it's a pretty common function in sticker editing apps. Right now manually adding a mirrored bitmap works, but won't it be better if the functionality is available from the library itself?

Probably by adding a 'flip' button on the frame (like the old Aviary SDK):

As of now their is no scope for this feature in the library.Hence as alternate solution you can mirror the bitmap before adding it to PhotoEditorView

This code will mirror the bitmap

BitmapDrawable flip(BitmapDrawable d)
{
    Matrix m = new Matrix();
    m.preScale(-1, 1);
    Bitmap src = d.getBitmap();
    Bitmap dst = Bitmap.createBitmap(src, 0, 0, src.getWidth(), src.getHeight(), m, false);
    dst.setDensity(DisplayMetrics.DENSITY_DEFAULT);
    return new BitmapDrawable(dst);
}

Yeah, I suppose we can use that option instead. I'll close this issue.

Thanks for this library!
