Detailed Description

Freetype font class.

Definition at line 940 of file stylebase.cpp.

Constructor & Destructor Documentation

a2dFontFreetypeData::a2dFontFreetypeData	(	const wxString &	filename = wxT( "" ),
		double	size = 0.0,
		wxFontEncoding	encoding = wxFONTENCODING_DEFAULT,
		int	faceindex = 0
	)

Constructor.

\param filename Filename of the vector font.
\param size Size in world coordinates.

Parameters

encoding

endocing of font

Definition at line 1062 of file stylebase.cpp.

Member Function Documentation

wxString a2dFontFreetypeData::GetFilename

(

bool

filenameonly = false

)

const

Get the font filename.

Parameters

filenameonly

The returned filename will be stripped of drive-letters and directories.

Returns

The filename of the font.

Definition at line 1233 of file stylebase.cpp.

const a2dGlyph * a2dFontFreetypeData::GetGlyph

(

wxChar

c

)

const

Get the glyph of a single character.

Returns

The glyph of the character, in a coordinate space, normalized to a font size m_sizeInPixels.

Definition at line 1359 of file stylebase.cpp.

double a2dFontFreetypeData::GetKerning ( wxChar  c1, wxChar  c2  ) const

virtual

Get kerning space between two characters.

Kerning is a method, which moves characters closer together/further apart, to improve the look of the font. Eg. the letter combination LT will be moved closer together. The return value is negative or positive, to respectively move characters closer together, or further apart.

Reimplemented from a2dFontRefData.

Definition at line 1614 of file stylebase.cpp.

void a2dFontFreetypeData::SetFilename

(

const wxString &

filename

)

Set the font filename and load the font.

Parameters

filename

The filename of the font. This may either be a full path, or just the fontname. In the latter case, the fontpath of a2dGlobals will be used to search the font.

static void a2dFontFreetypeData::SetLoadFlags ( wxInt32  loadMethodMask )

inlinestatic

Set the way glyphs are loaded by freetype. Important for small fonts. a2d_LOAD_DEFAULT; a2d_LOAD_DEFAULT | a2d_LOAD_NO_HINTING; a2d_LOAD_DEFAULT | a2d_LOAD_FORCE_AUTOHINT;
