vflip − flip or transpose an image about an axis

vflip [-H] [if=<infile>] [of=<outfile>] [-i] [-v] [-xy] [-xz] [-yz] [-x] [-y] [-z] [-t] [-3d]

Vflip transposes or flips an image about the specified axis. By default 2D images are assumed and a 2D transpose operation is performed.

All image file formats are accepted. Operations involving the Z dimension employs the 3D image structure which requires that the memory is large enough to hold all image data.

-xy

transpose about the x-y axis

-xz

transpose about the x-z axis

-yz

transpose about the y-z axis

-x

flip about the x axis

-y

flip about the y axis

-z

flip about the z axis

-t

explicit transpose about the x-y axis. (the same as -xy)

-3d

assume a 3D image when processing the data

-i

Transpose about the XY axis inverse diagonal

-v

verbose mode, messages are printed to stderr
