class	GeomTextGlyph

Detailed Description

A representation of a single glyph (character) from a font.

This is a piece of renderable geometry of some kind.

Definition at line 28 of file textGlyph.h.

Constructor & Destructor Documentation

◆ TextGlyph()

TextGlyph::TextGlyph	(	int	character,
		PN_stdfloat	advance = `0`
	)

inline

This constructor makes an empty glyph.

Definition at line 18 of file textGlyph.I.

Member Function Documentation

◆ get_quad()

bool TextGlyph::get_quad	(	LVecBase4 &	dimensions,
		LVecBase4 &	texcoords
	)		const

inline

Assuming that this glyph is representable as a textured quad, returns its dimensions and UV range.

Returns false if it is not representable as a quad, or if it is whitespace.

The order of the components is left, bottom, right, top.

Definition at line 104 of file textGlyph.I.

◆ has_quad()

bool TextGlyph::has_quad ( ) const

inline

Returns true if this glyph contains the definition for a simple quad, rather than a more complex piece of geometry.

You may still call get_geom() even if this returns true, which will synthesize a Geom for this quad.

Definition at line 92 of file textGlyph.I.

◆ is_whitespace()

bool TextGlyph::is_whitespace ( ) const

virtual

Returns true if this glyph represents invisible whitespace, or false if it corresponds to some visible character.

Definition at line 37 of file textGlyph.cxx.

◆ set_geom()

void TextGlyph::set_geom	(	GeomVertexData *	vdata,
		GeomPrimitive *	prim,
		const RenderState *	state
	)

Sets the geom from a pre-built Geom object.

Any quad parameters assigned will be cleared.

Definition at line 119 of file textGlyph.cxx.

References PT().

Member Data Documentation

◆ get_advance

PN_stdfloat TextGlyph::get_advance

inline

Returns the distance by which the character pointer should be advanced after placing this character; i.e.

the approximate width the character takes up on the line.

Definition at line 46 of file textGlyph.h.

◆ get_character

int TextGlyph::get_character

inline

Returns the Unicode value that corresponds to the character this glyph represents.

Definition at line 44 of file textGlyph.h.

◆ get_state

const RenderState * TextGlyph::get_state

inline

Returns the state in which the glyph should be rendered.

Definition at line 45 of file textGlyph.h.
