Parameter descriptions

Input: Input raster channel(s)

Specifies the input image channels to be mirrored.

At least one channel must be specified. Duplicates are not allowed.

Output: Output mirrored channel(s)

Specifies the output raster channels to receive the mirrored image if FILO is defaulted or equal FILE.

If FILO is created then DBOC defaults or is ignored.

At least one channel must be specified. Duplicates are not allowed.

The output channel may be the same as the input channel; if so, existing data will be overwritten.

Mirror Axis

Optionally specifies the axis of rotation to use for mirroring.

Available options are:

InputGCP: Input GCP segment

Optionally specifies the GCP2 segment to be mirrored.

OutputGCP: Output GCP segment

Specifies the output GCP segment to receive the mirrored GCP segment. If an input GCP segment is specified, a new output GCP segment is automatically created.

Details

MIRROR creates a set of mirror images along the vertical or horizontal axis, given a specified window (DBIW) within a set of input channels (DBIC), and saves the mirrored result in new file FILO if specified or input file as the defined output channels (DBOC).

For rotation about the vertical axis, the gray-level values of the first and last input pixels on each line of image data are swapped, the second and second-last pixels on each line are swapped, and so on. For rotation about the horizontal axis, the gray-level values of the first and last input lines are swapped, the second and second-last lines are swapped, and so on.

MIRROR can be run on aircraft radar and MSS image data, to convert left-looking images to right-looking images, or to invert ascending radar data to descending order.
