ROTATE/COUNTER_CLOCK in out [factor]
16
rotate an image by multiples of 90 degrees counter_clockwise
19
Rotate an image by multiples of 90 degrees counter_clockwise.
22
ROTATE/COUNTER_CLOCK in out [factor]
24
in = input frame (2-dim image)
26
out = output frame (will be created by this command)
28
factor = 1, 2 or 3 for 90, 180 or 270 degrees rotation;
30
defaulted to 1, i.e. 90 degrees
33
This command is not a rotation around a given point but strictly
34
speaking just a rearrangement of the image pixels. Values for start
35
and stepsize of result frame are adjusted accordingly.
37
Using REBIN/ROTATE with a rotation angle of 90.0 degrees will yield
38
the same data in the result frame as ROTATE/COUNTER, but start and
39
stepsize will be different!

ROTATE/CLOCK, REBIN/ROTATE

ROTATE/COUNTER paloma blanca 2
47
rotate image paloma.bdf by 180 degrees counter_clockwise and store
48
result into frame blanca.bdf
