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
