int s2opend(char *device, int argc, char **argv);
</code>

Description

Open the S2PLOT device (device string version). This is like the PGPlot open function, which allows for setting the device via the environment, via standard input when the program is run, or via an explicit setting in the code. Options are: /S2MONO - mono device, windowed /S2MONOF - mono device, full screen if possible /S2PASSV - passive stereo device, windowed (not for projection) /S2PASSVF - passive stereo device, full screen if possible /S2ACTIV - active stereo device, windowed /S2ACTIVF - active stereo device, full screen if possible /S2FISH - fisheye projection, windowed /S2FISHF - fisheye projection, full screen if possible /S2TRUNCB - truncated-base fisheye, windowed display /S2TRUNCBF - truncated-base fisheye, full screen if possible /S2TRUNCT - truncated-top fisheye, windowed display /S2TRUNCTF - truncated-top fisheye, full-screen if possible /S2ANA - anaglyph stereo (red(L), blue(R)), windowed /S2ANAF - anaglyph stereo (red(L), blue(R)), full screen if possible /S2DSANA - anaglyph stereo (red(L), blue(R)), pre-desaturated, windowed /S2DSANAF - anaglyph stereo (red(L), blue(R)), pre-desaturated, full-screen If the device string is given as blank or empty, then the value of the environment variable S2PLOT_DEV will be used, and should be set to one of the above. If this value is not found, then the behaviour is as for "/?" described below.

If the device string is given as "/?" then the user will be prompted for their choice when the program is run. The default choice will be the value of S2PLOT_DEV if it contains a valid device.

Code Example

#include <stdio.h>
#include <stdlib.h>
#include "s2plot.h"

int main(int argc, char *argv[])
{
   s2opend("/?", argc, argv);			/* Prompt for display type */
   s2swin(-1.,1., -1.,1., -1.,1.);		/* Set the window coordinates */
   s2box("BCDET",0,0,"BCDET",0,0,"BCDET",0,0);	/* Draw coordinate box */
   s2show(1);					/* Open the s2plot window */
   
   return 1;
