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. ---------------------------------------------------------------- PLROW: Task to plot a series of X slices in the XY plane. DOCUMENTOR: Gary Fickling. RELATED PROGRAMS: SLICE, SL2PL, PRTPL, 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 PRTPL, 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.
