Library

OpenGLUT - fonts

#include <openglut.h>

float
glutStrokeLength(void *fontID, const unsigned char *string);

fontID

A GLUT stroked font identifier.

string

A C-style (NUL-terminated) string.

This function reports the sum of the widths of the characters in a

string,

using the font metrics of a given

font.

Like glutStrokeString(), glutStrokeLength() respects newlines in the input.

Returns 0 if:
- The

fontID

is out of range.
- The

string

NULL.

- All characters in the

string

are zero-width.

Refer to glutStrokeWidth() for notes on the nature of this function's return value, and for comparisons to old GLUT and freeglut.
