glcGetCharMetric(3G)	  OpenGL Character Renderer	  glcGetCharMetric(3G)

NAME
     glcGetCharMetric - measure a character

C SPECIFICATION
     GLfloat* glcGetCharMetric( GLint inCode,
				GLCenum inMetric,
				GLfloat *outVec )

PARAMETERS
     inCode    Specifies the character to measure.

     inMetric  Specifies the metric to measure, either GLC_BASELINE or
	       GLC_BOUNDS.

     outVec    Specifies a vector in which to store value of inMetric for the
	       specified character.

DESCRIPTION
     glcGetCharMetric is identical to glcRenderChar but instead of rendering
     the character that inCode is mapped to, glcGetCharMetric only measures
     the baseline or bounds (depending on inMetric) of the character.
     glcGetCharMetric stores the value of the baseline (or bounds) in outVec.

     If inMetric is GLC_BOUNDS, a vector of eight values is returned in
     outVec. The vector starts in the lower left corner and continues in a
     counterclockwise direction.

ERRORS
     GLC_STATE_ERROR is generated if the issuing thread has no current GLC
     context.

SEE ALSO

     glcMeasureString
