hcp


             hcp  
             hcpon  
 
	    hcpoff  
     The hcp command sends the picture displayed in the current graphics  
     window to the hardcopy file.  (The name of the default hardcopy file  
     can be specified using hcp_file; each individual graphics window may  
     have its own hardcopy file as specified by the window command.)  
     The hcpon command causes every fma (frame advance) command to do  
     and implicit hcp, so that every frame is sent to the hardcopy file.  
     The hcpoff command reverts to the default "demand only" mode.

hcp_file


             hcp_file, filename, dump=0/1, ps=0/1  
 
     sets the default hardcopy file to FILENAME.  If FILENAME ends with  
     ".ps", the file will be a PostScript file, otherwise it will be a  
     binary CGM file.  By default, the hardcopy file name will be  
     "Aa00.cgm", or "Ab00.cgm" if that exists, or "Ac00.cgm" if both  
     exist, and so on.  The default hardcopy file gets hardcopy from all  
     graphics windows which do not have their own specific hardcopy file  
     (see the window command).  If the dump keyword is present and non-zero,  
     the current palette will be dumped at the beginning of each frame  
     of the default hardcopy file (default behavior).  With dump=0,  
     all colors are converted to a gray scale, and the output files are  
     smaller because no palette information is included.  
     Use ps=1 to make "Aa00.ps", "Ab00.ps", etc by default instead of CGM.  
     The dump= and ps= settings persist until explicitly changed by a  
     second call to hcp_file; the dump=1 setting becomes the default for  
     the window command as well.

hcp_finish


             filename= hcp_finish()  
          or filename= hcp_finish(n)  
 
     closes the current hardcopy file and returns the filename.  
     If N is specified, closes the hcp file associated with window N  
     and returns its name; use hcp_finish(-1) to close the default  
     hardcopy file.

hcp_out


             hcp_out  
          or hcp_out, n  
 
     finishes the current hardcopy file and sends it to the printer.  
     If N is specified, prints the hcp file associated with window N;  
     use hcp_out,-1 to print the default hardcopy file.  
     Unless the KEEP keyword is supplied and non-zero, the file will  
     be deleted after it is processed by gist and sent to lpr.

hcps


             hcps, name  
 
     writes the picture in the current graphics window to the  
     PostScript file NAME+".ps" (i.e.- the suffix .ps is added to NAME).  
     Legends are not written, but the palette is always dumped.

hide


             hide=   plotting keyword  
 
     sets the visibility of a plotted element.  The default is hide=0,  
     which means that the element will be visible.  Use hide=1 to remove  
     the element from the plot (but not from the display list).

histeq_scale


             histeq_scale(z, top=top_value, cmin=cmin, cmax=cmax)  
 
     returns a byte-scaled version of the array Z having the property  
     that each byte occurs with equal frequency (Z is histogram  
     equalized).  The result bytes range from 0 to TOP_VALUE, which  
     defaults to one less than the size of the current palette (or  
     255 if no pli, plf, or palette command has yet been issued).  
     If non-nil CMIN and/or CMAX is supplied, values of Z beyond these  
     cutoffs are not included in the frequency counts.

hollow


             hollow=   plotting keyword  
          or aspect=   plotting keyword  
 
     set the appearance of the "darts" of a vector field plot.  The  
     default darts, hollow=0, are filled; use hollow=1 to get just the  
     dart outlines.  The default is aspect=0.125; aspect is the ratio  
     of the half-width to the length of the darts.  Use the color  
     keyword to control the color of the darts.  
   PLOTTING COMMANDS: plv
