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()
|
inline |
This constructor makes an empty glyph.
Definition at line 18 of file textGlyph.I.
Member Function Documentation
◆ get_quad()
|
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()
|
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()
|
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.

Member Data Documentation
◆ 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
|
inline |
Returns the Unicode value that corresponds to the character this glyph represents.
Definition at line 44 of file textGlyph.h.
◆ get_state
|
inline |
Returns the state in which the glyph should be rendered.
Definition at line 45 of file textGlyph.h.
