But it doesn't, since the angle does not tell you the flip count. And -180 and 180 degree rotations are identical in the image too. It is possible to get an upside down flipped image in at least three ways: the original vertical flip, a horizontal flip - 180 degrees and a horizontal flip + 180 degrees (order doesn't matter). The vertical flip button is now a shortcut for the last method. >From a mathematical/UI perspective it is a bug: vertical flip just aint a pure flip anymore because of the rotation angle shown afterwards. From a users perspective that might look strange or not but more important, it doesn't actually help in any way. Balancing the horizon after a vertical flip is now a bit clumsy: the angle keeps flipping between 180 and -180 without change in the image. This verical flip implementation is likely to result in bug reports. I think (and Martin hinted me in that direction) that a photographer might want a horizontal flip (estetical reason) or a 180 degree/upside down button (unusual camera orientation) but never a vertical flip. Neither old or new vertical flip button implementations help here so if you really want to get rid of the old vertical flip I'd suggest replacing it with a 180 degree button. -- Frank ------------------------------------------------------------------------------ Come build with us!
