class
TextFont
¶ Bases:
TypedReferenceCount
,Namable
An encapsulation of a font; i.e. a set of glyphs that may be assembled together by a
TextNode
to represent a string of text.This is just an abstract interface; see
StaticTextFont
orDynamicTextFont
for an actual implementation.Inheritance diagram

get_glyph
(int character)¶ Gets the glyph associated with the given character code, as well as an optional scaling parameter that should be applied to the glyph’s geometry and advance parameters. Returns the glyph on success. On failure, it may still return a printable glyph, or it may return NULL.
-
virtual PN_stdfloat
get_kerning
(int first, int second) const¶ Returns the amount by which to offset the second glyph when it directly follows the first glyph. This is an additional offset that is added on top of the advance.
-
PN_stdfloat
get_line_height
(void) const¶ Returns the number of units high each line of text is.
-
PN_stdfloat
get_space_advance
(void) const¶ Returns the number of units wide a space is.
-
bool
is_valid
(void) const¶ Returns true if the font is valid and ready to use, false otherwise.
-

set_line_height
(PN_stdfloat line_height)¶ Changes the number of units high each line of text is.

set_space_advance
(PN_stdfloat space_advance)¶ Changes the number of units wide a space is.
