s2sch
Set the character height in "arbitrary" units.
Prototype
void s2sch(float size);
Description
Set the character height in "arbitrary" units. The default character size is 1.0, corresponding to a character about 15 pixels in size. Changing the character height also changes the scale of tick marks and symbols.
See Also
s2qch | Query the character height. |
s2slw | Set the linewidth in pixels. |
PGPLOT Equivalent
Code Example
#include <stdio.h>
#include <stdlib.h>
#include <time.h>
#include "s2plot.h"
int main(int argc, char *argv[])
{
float x = 0.0; /* Text location */
float y = 0.0;
float z = 0.0;
int N = 4; /* Number of strings */
int i; /* Loop variable */
float height; /* Height of text */
char string[32]; /* String of text */
srand48((long)time(NULL)); /* Seed random numbers */
s2opend("/?",argc, argv); /* Open the display */
s2swin(-1.,1., -1.,1., -1.,1.); /* Set the window coordinates */
s2box("BCDET",0,0,"BCDET",0,0,"BCDET",0,0); /* Draw coordinate box */
for (i=0;i<N;i++) {
s2sci((i%15)+1); /* Set the colour */
height = (i+1)*0.3;
sprintf(string,"Height = %.1f\n",height); /* Create the string */
x = drand48()*1.6 - 0.8; /* Random text location */
y = drand48()*1.6 - 0.8;
z = drand48()*1.6 - 0.8;
s2sch(height); /* Set text height */
s2textxy(x,y,z,string); /* Write some text in x-y plane */
}
s2show(1); /* Open the s2plot window */
return 1;
