This function allows you to flip a frame on its vertical centre
axis. If this sounds confusing: When mirroring on a vertical axis left
and right are swapped over, so everything to the left of the centre of
the frame will appear on the right, and vice versa. That is why it's
called mirror horizontally
. Of course, any text in the frame
will also appear mirror-reversed.
This function is very easy to use: Simply select a frame and click on the icon. The icon will appear selected and the contents of the frame will appear mirror-reversed. If you click on the icon a second time, the frame will return to its original format.
At the same time the icon shows whether a selected frame is mirror-reversed. When you select a mirrored frame, this icon will automatically be displayed as selected (inverse video).
