Flip Layer. Flips the layer horizontally, vertically, or both, after applying crop= and before rotate= and extend=.
Flip layer horizontally (left-right).
Flip layer vertically (up-down).
Flip both horizontally and vertically.
May also be applied to text layers.
Some commands, including extend= , implicitly apply to layer 0 instead of the composite layer when layer=comp is selected. In such scenarios, all commands that are assigned automatically to layer 0 will be applied before the commands which apply to layer=comp . Thus, when layer=comp , extend= is applied before flip= .
The flipped layer is positioned based on the layer anchor; different flip= values will result in different layer positions when the anchor is not located at the center of the layer.
Layer command. Applies to the current layer or to the composite image if layer=comp . Ignored by effect layers.
