Detailed Description

The abstract base class for glyphs. A glyph is a shape with its own coordinate system. It is converted to a particular size only at the time of drawing. Glyph implementations may choose to cache one or more sizes.

Member Function Documentation

TFixed CartoType::CGlyph::AdvanceInEm

(

)

const [inline]

Return the linear advance in em.

TFixed CartoType::CGlyph::AscentInEm

(

)

const [inline]

Return the unrotated ascent in em.

TFixed CartoType::CGlyph::DescentInEm

(

)

const [inline]

Return the unrotated descent in em.

virtual TResult CartoType::CGlyph::Draw	(	CGraphicsContext *	aGc,
		const TTypefaceInstance &	aInstance,
		double	aOriginX,
		double	aOriginY,
		TRect *	aBounds
	)		[pure virtual]

Draw or measure a glyph with its reference point at (aOriginX,aOriginY). The glyph is drawn if aGc is non-null. The glyph is measured if aMetrics is non-null.

virtual int32 CartoType::CGlyph::MemoryUsed

(

)

[pure virtual]

Return the number of bytes of heap memory used by a glyph.
