ANSI-C program: MLI_copy.c
NAME
MLI_copy - Copy user defined image segment from input MLI image
to output MLI (float).
SYNOPSIS
MLI_copy <MLI_in> <MLI_in_par>
<MLI_out> <MLI_out_par> [roff] [nr] [loff]
[nl]
| <MLI_in> | (input) multi-look intensity image (float) |
| <MLI_in_par> | (input) ISP image parameter file for input MLI |
| <MLI_out> | (output) selected MLI section (float) |
| <MLI_out_par> | (output) ISP image parameter file for output MLI |
| [roff] | offset to starting range sample (enter - for default: 0) |
| [nr] | number of range samples (enter - for default: to end of line |
| [loff] | offset to starting line (enter - for default: 0) |
| [nl] | number of lines to copy (enter - for default: to end of file) |
EXAMPLES
To extract 1000 lines of 1024 range pixels skipping 216 range
samples and 311 lines:
MLI_copy 1352.mli 1352.mli.par 1352s.mli 1352s.mli.par
216 1024 311 1000
DESCRIPTION
MLI_copy extracts the user defined section from the
input multi-look intensity (MLI) image and writes it out as
a new MLI file.
Data processed are in float format (4 bytes/sample). A new ISP
image parameter file is created for the MLI to describe the
geometry of the output image file. Starting, center, and ending
times, and the near, center and far slant ranges are calculated
for the selected SLC segment. The Doppler polynomial is also
adjusted for th relative image offsets.The output SLC together
with its parameter file contains the full information needed for
further processing including geocoding.
For the first range pixel and first azimuth line of the input
MLI to coincide with the output image select roff=0
and loff=0, respectively,.
OPTIONS
The selected image section may extend outside of the range of
valid data of the input SLC. The NULL value assigned to these
values is 0.0.
