How to configure Color Factory to rotate or mirror pictures in a channel.
Mirroring and rotation
Where: Channel | Image Size | Mirror and Rotation tab
The Mirror and Rotation tab may be used to flip images vertically or horizontally, and you may set the default direction to rotate incoming images. You may even enter the rotational angle manually by clicking in the text field and entering a value (for instance 22,5 for 22,5 degrees)
Note that the values are counter clockwise, meaning that in order to rotate an image 90 degrees clockwise you should enter 270 in the value field. (The preset values in the drop down list should make this clear).
