s2qtxtxyf
Find the bounding box of text drawn with s2textxyf.
Prototype
void s2qtxtxyf(float *x1, float *x2, float *y1, float *y2, float x, float y, float z,
float flipx, float flipy, char *text, float pad);
Description
Find the bounding box of text drawn with the s2textxyf function. For convenience, pad can be given > 0.0 to obtain padding around the text of pad percent.
See Also
| s2qtxtxy | Find the bounding box of text drawn with s2textxy. |
| s2textxyf | Draw flipped text in the xy plane at a fixed z coordinate. |

Code Example
#include <stdio.h>
#include <stdlib.h>
#include "s2plot.h"
int main(int argc, char *argv[])
{
float x = 0.0;
float y = 0.5;
float z = 0.2;
float flipx = -1.0;
float flipy = -1.0;
float x1,x2, y1,y2; /* Bounding coordinates */
char string[32] = "S2PLOT is great!";
float pad = 0.5; /* Padding around text */
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 */
s2sci(S2_PG_YELLOW);
s2slw(2); /* Set line width */
s2textxyf(x,y,z,flipx,flipy,string); /* Write some flipped text in x-y plane */
s2qtxtxyf(&x1,&x2, &y1,&y2, x,y,z, flipx, flipy, string, pad);
/* Query bounding box for flipped text */
s2sci(S2_PG_GREEN);
s2rectxy(x1,x2, y1,y2, z-0.01); /* Draw bounding rectangle */
s2show(1); /* Open the s2plot window */
return 1;
}
