NAME¶
glutStrokeWidth —
Returns the width in pixels of a character in a given
font.
LIBRARY¶
OpenGLUT - fonts
SYNOPSIS¶
#include
<openglut.h>
float
glutStrokeWidth(void
*fontID, int
character);
PARAMETERS¶
fontID
A GLUT stroked font identifier.
character
A character code.
DESCRIPTION¶
This function reports how far the model space origin will advance if you putput this
character
in the font named by
fontID.
Not all letters will use their full width, especially in fixed-width fonts.
Returns 0 if
character
is out of range or if the
fontID
is invalid.
CAVEATS¶
Historically, this function has been described as returning a pixel-width, but was implemented to return the width in model-space units, rounded to integers. GLUT never resolved this, and freeglut duplicated the confusion. OpenGLUT has decided to stay in model-space and to return the unrounded floating point value. An unreleased GLUT 3.8 was supposed to include glutStrokeWidthf() and glutStrokeLengthf() (note the *f suffixes), but that is not in wide use.
TODO¶
Determine if any glyphs are either wider than this function or if they render outside of the bounding box given by
(0,-descent)
by
(width,height-descent)
.
