glcGetMaxCharMetric(3G)	  OpenGL Character Renderer    glcGetMaxCharMetric(3G)

NAME    [Toc]    [Back]

     glcGetMaxCharMetric - measure layout of characters

C SPECIFICATION    [Toc]    [Back]

     GLfloat* glcGetMaxCharMetric( GLCenum inMetric,
				   GLfloat *outVec )

PARAMETERS    [Toc]    [Back]

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

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

DESCRIPTION    [Toc]    [Back]

     glcGetMaxCharMetric measures the layout that would	result from rendering
     all mapped	characters at the same origin. This contrasts with
     glcGetStringCharMetric, which measures characters as part of a string,
     that is, influenced by kerning, ligatures,	and so on.

     The command stores	the value of the metric	identified by inMetric in
     outVec. Currently,	you can	choose from GLC_BASELINE and GLC_BOUNDS. If
     you choose	GLC_BOUNDS, the	vector returned	in outVec starts at the	lower
     left corner and continues in a counterclockwise direction.

     If	the command does not raise an error, its return	value is outVec.

ERRORS    [Toc]    [Back]

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