INPUTS
USERID -32000.0 32000.0 User ID - ignored
INNAME Image name(name).
INCLASS Image name(class).
INSEQ 0.0 9999.0 Image name(seq. #). 0=>high
INDISK 0.0 9.0 Disk drive #. 0=>any
BLC 0.0 4096.0 Bottom left corner of image
0=>entire image
TRC 0.0 4096.0 Top right corner of image
0=>entire image
PIXRANGE Clip at these intensities.
0,0=> map min, max.
YINC 0.0 4096.0 Plot every YINCth row

LTYPE -410.0 410.0 Type of labeling: 1 border,
2 no ticks, 3 standard, 4 rel
to center, 5 rel to subim cen
6 pixels, 7-10 as 3-6 with
only tick labels

HELP SECTION
PLROW
Type: Task
Use: PLROW will generate a plot file for a plot of the rows of
the XY plane.
Adverbs:
USERID......The ID of the owner of the image. Ignored
INNAME......Image name (name). Standard defaults.
INCLASS.....Image name (class). Standard defaults.
INSEQ.......Image name (seq. #). 0 => highest.
INDISK......Disk unit #. 0 => any.
BLC.........Bottom Left Corner of image to contour.
(0,0) means (1,1).
TRC.........Top Right Corner of image to contour.
(0,0) means top right corner of map.
PIXRANGE....Clip at these intensities. 0,0=> map min, max.
YINC........Plot every YINCth row
OFFSET......Offset of rows on plot in units of the image. The
default is 0.25 of the actual PIXRANGE being used
and is applied if OFFSET <= 0 or OFFSET > 2.5 *
actual PIXRANGE.
LTYPE.......Labelling type, see HELP LTYPE for details:
1 = border, 2 = no ticks, 3 or 7 = standard, 4 or 8 =
relative to ref. pixel, 5 or 9 = relative to subimage
(BLC, TRC) center, 6 or 10 = pixels. 7-10 all labels
other than tick numbers and axis type are omitted.
Less than 0 is the same except that the plot file
version number and create time are omitted.
Add n * 100 to alter the metric scaling.
DOTV........> 0 => plot directly on the TV device, otherwise
make a plot file for later display on one or
more devices (including the TV if desired).
GRCHAN......Graphics channel (1 - 7) to use for line drawing.
0 => 1.
EXPLAIN SECTION
PLROW: Task to plot a series of X slices in the XY plane.
DOCUMENTOR: Gary Fickling.
RELATED PROGRAMS: SLICE, SL2PL, LWPLA, TKPL, TVPL
PURPOSE
PLROW generates a plot extension file containing a plot
of the rows of a map along the XY plane. The plot itself may
be displayed on a printer, TEK screen, or TV graphics channel
by the tasks LWPLA, TKPL, or TVPL respectively.
COMMENTS
The program draws a straight line from one pixel value to
the next, but will interpolate for rows having fewer than 256
pixels.
OFFSET
This value is the offset on the plot of every row from its
neighbor as in map units. If a value <= zero is input, then the
rows are offset by 0.25 of the actual PIXRANGE being plotted.
If a positive value is input then all rows except the first are
offset in the Y direction. The default is a good starting
guess.
EXECUTION TIME:
Almost always less than 1 min.
