PROGRAM NAME
iflip - Reflect Image Data Along Either Width Or Height Axes
DESCRIPTION
iflip
performs the reflection of image data values and the validity mask in either
the width or height directions.
If the source object has explicit time or location data, the data is
transferred to the destination object but is
NOT flipped.
Note that location data can be reflected using
klocxform.
If the source object contains MAP data, it will be directly transferred to
the destination object.
If the source object has the attribute KPDS_KERNEL_ORIGIN set to specify a
"hot spot"
in the image, then the kernel origin is flipped along the same specified
axes (width and/or height).
REQUIRED ARGUMENTS
- -i
-
type: infile
desc: Source (input) object
- -o
-
type: outfile
desc: Destination (output) object
Group; you must specify AT LEAST ONE of:
- -w
-
type: flag
desc: reflection in the WIDTH direction
AND/OR
- -h
-
type: flag
desc: reflection in the HEIGHT direction
OPTIONAL ARGUMENTS
none
EXAMPLES
% iflip -i source_obj -o dest_obj
performs image reflection of internal parameters about the width axis.
% iflip -i source_obj -o dest_obj -w -h
performs image reflection of internal parameters about the width and height axes.
SEE ALSO
kflip(1), klocxform(1)
RESTRICTIONS
iflip
performs the reflection of parameters in the VALUE and MASK data segments.
If LOCATION and TIME segments exist, the reflection is performed in the
VALUE and MASK segments at this time. LOCATION and TIME are transferred
directly. To reflect LOCATION data, see
klocxform
