OPERATOR
flip --- perform a number of geometric transforms on an image
DESCRIPTION
The flip operator performs one of several common geometric transformations on
its input image. The transformation type is specified by the op parameter:
flip-y: y' = -y
flip-x: x' = -x
x-pose: x' = y
r-90 : x' = y and y' = -y
r-180 : x' = -x and y' = -y
r-270 : x' = y and x' = -x
