graphprt#

Purpose#

Controls automatic printer hardcopy and conversion file output. Note: This function is for use with the deprecated PQG graphics. Use the func:plotSave function instead.

Format#

graphprt(str)#

Parameters:: str (string) – control string.

Examples#

Automatic print using a single graphics call:

library pgraph;
graphset;

load x,y;

// Tell xy to print
graphprt("-p");

// Create graph and print
xy(x, y);

Automatic print using multiple graphic panels. Note graphprt() is called once just before the endwind() call:

library pgraph;
graphset;

load x,y;

// Create two windows
begwind;
window(1, 2, 0);

// First graphics call
setwind(1);
xy(x, y);

// Second graphics call
nextwind;
xy(x, y);


// Print page containing all graphs
graphprt("-p");
endwind;

The next example shows how to build a string to be used with graphprt():

library pgraph;
graphset;
load x,y;

// Name of output file
cvtnam = "mycvt.eps";

// Concatenate options into one string
cmdstr = "-c=1" $+ " -cf=" $+ cvtnam;
cmdstr = cmdstr $+ " -q";

/*
** Tell `xy` to convert and
** close
*/
graphprt(cmdstr);

// Create graph and convert
xy(x, y);

The above string cmdstr will read as follows:

"-c=1 -cf=mycvt.eps -q"

Remarks#

graphprt() is used to create hardcopy output automatically without user intervention. The input string str can have any of the following items, separated by spaces. If str is a null string, the interactive mode is entered. This is the default.

-p	print graph
-po=c	set print orientation: l: landscape p: portrait
-c=n	convert to another file format: 1: Encapsulated PostScript file. 3: HPGL Plotter file. 5: BMP (Windows Bitmap). 8: WMF (Windows Enhanced Metafile).
-cf=name	set converted output file name.
-i	minimize (iconize) the graphics window.
-q	close window after processing.
-w=n	display graph, wait n seconds, then continue.
