ANSI-C program: clear_flag.c
NAME
clear_flag - Resets flags in flagfile used throughout the various
steps necessary for the unwrapping of the interferometric
phase.
SYNOPSIS
clear_flag <flag_file> <width>
<flag_bits> [xmin] [xmax] [ymin] [ymax]
| <flag_file> | phase unwrapping flag filename |
| <width> | number of samples/row |
| <flag_bits> | byte with value of flag(s) to be cleared |
| [xmin] | starting range pixel offset (default = 0) |
| [xmax] | last range pixel offset (default = width-1) |
| [ymin] | starting azimuth row offset, relative to start (default = 0) |
| [ymax] | last azimuth row offset, relative to start (default = nlines-1) |

clear_flag 1352_1610.flag 2500 8(resets low SNR
flag)
clear_flag 1352_1610.flag 2500 16(resets visited
residue flag)
clear_flag 1352_1610.flag 2500 32(resets starting
node of a branch flag)
clear_flag 1352_1610.flag 2500 64(resets cuts
flag)
clear_flag 1352_1610.flag 2500 128(resets lawn
area flag)
clear_flag 1352_1610.flag 2500 80(resets cuts and
visited area flags flag)
DESCRIPTION
clear_flag allows to reset individual or multiple flags of the
flagfile. There are 8 bits stored for each pixel,each is a flag
bit. The meaning of the individual bits is defined in the
typedef_ISP.h file. The information contained in the
flagfile can be examined with the programs disflag or rastree.
