SQASH: Collapses several planes in a cube into one plane/row
INNAME Input name(name).
INCLASS Input name(class).
INSEQ 0.0 9999.0 Input name(seq. #). 0=>high
INDISK 0.0 9.0 Input disk drive #. 0=>any
OUTNAME Output name(name).
OUTCLASS Output name(class).
OUTSEQ -1.0 9999.0 Output name(seq. #).
0 => highest unique
OUTDISK 0.0 9.0 Output image disk drive #
0 => highest with room
BLC 0.0 4096.0 Bottom left corner of image
TRC 0.0 4096.0 Top right corner of image
BDROP -7.0 7.0 > 0 => sum over axis BDROP
< 0 => sum all axes >= -BDROP
DPARM 0.0 6.0 (1) = 0 weighted average,
1 weighted rms
2 straight average
3 straight rms
4 sum, 5 max 6 min
(2) > 0 ignore blanked pixels
(3) Use INTEXT for weights
INTEXT Text file listing weights
Use: Task to collapse several planes in a cube into one plane or row.
A cube may still be left if the image started with > 3 "real"
INNAME......Input name of image(name). Standard defaults.
INCLASS.....Input name of image(class). Standard defaults.
INSEQ.......Input name of image(seq. #). 0 => highest.
INDISK......Disk drive # of image. 0 => any.
OUTNAME.....Output name of image(name). Standard defaults.
OUTCLASS....Output name of image(class). Standard defaults.
OUTSEQ......Output name of image(seq. #). 0 => highest unique
OUTDISK.....Disk drive # of Output image. 0 => highest with
BLC.........The bottom left-hand pixel of the input image
which becomes the bottom left corner of the
subimage. The value (0,0) means (1,1).
TRC.........The top right-hand pixel of the input image
which becomes the top right corner of the
subimage. The value (0,0) means take the top
right hand corner of the image.
BDROP.......If > 0, use axis BDROP only
If < 0, use all axes >= -BDROP
Note BDROP > 1 or BDROP < -1 is required here. It is
possible to collapse the 2nd axis to a single pixel.
If BDROP = 2, you may want TRANS with TRANCODE '132' on
the output to view the image. If BDROP=-2, the result
is a single row - run SLICE on that to view the results.
(1) 0: weighted average; 1: weighted rms; 2: average;
3: rms; 4: sum; 5: maximum; 6: minimum
(2) > 0 => ignore blanks unless all contributing
planes are blank at the pixel
<= 0 => if any plane is blanked at a pixel,
blank that pixel on output
(3) > 0 use INTEXT for weights
INTEXT......Text file giving weights
