INP=PIC
or INP=(PIC,LOC)
The primary input image (PIC) will be reproduced as the output image
with scribed rectangles. The maximum image width is 2048 samples.
The optional secondary input (LOC) is used to specify the pixel locations to
be scribed inside rectangles. Each record of LOC should contain a list of
line-sample coordinates (L,S) in REAL data format (single precision floating
point) as follows:
L1,S1,L2,S2,L3,S3,...
A maximum of 900 pixel locations may be input.
In certain applications (e.g. TRACKER3) the matching pixel locations from
pairs of images (tiepoints) may be interleaved in LOC:
L1,S1,U1,V1,L2,S2,U2,V2,L3,S3,U3,V3,....
If the keyword 'ODD_ONLY is specified, then pixel coordinates (L1,S1), (L2,S2),
(L3,S3),... are used.
If the keyword 'EVENONLY is specified, then pixel coordinates (U1,V1), (U2,V2),
(U3,V3),... are used.
The output image will contain the input with scribed rectangles.
INTEGER-OPTIONAL Starting line.
INTEGER-OPTIONAL Starting sample.
INTEGER-OPTIONAL Number of lines.
INTEGER-OPTIONAL Number of samples.
TYPE=INTEGER
The interior dimensions of the rectangles.
The exact dimensions depend on the fractional location of the
rectangle center and wither the box is an odd or even number of
pixels:
FRACTIONAL PART=F SIZE=N CENTERS
ODD EVEN LINE SAMPLE
0.0 .LE. F .LT. .25 N N-1 L S
.25 .LE. F .LT. .25 N-1 N L+1/2 S+1/2
.75 .LE. F .LT. 1.0 N N-1 L+1 S+1
The maximum boxsize is 30 x 30 samples. Default is BOXSIZE=8.
DATA=(l1,s2,l2,s2,l3,s3,...) The center locations of rectangles to be scribed specified as (line,samp) pairs of floating point numbers. A maximum of 500 locations can be input.
MAXDN = 3000 The DN value of the scribed rectangle will be 0 or MAXDN, depending upon whether the mean value of the pixels on the perimeter are greater than or less than MAXDN/2, respectively. Default MAXDN=255 for byte data and 511 for halfword data. Note the MAXDN parameter is useful primarily for halfword data since the default is only appropriate for old Mariner missions which returned 9 bit data.
