Member Function Documentation

bool STLL::FontFace_c::containsGlyph

(

char32_t

ch

)

check if a given character is available within this font

Parameters

ch	the unicode character to check

Returns

true, when the character is available within the font, false otherwise

int32_t STLL::FontFace_c::getAscender

(

void

)

const

Get the ascender of the font with multiplication factor of 64.

Returns

ascender of font

int32_t STLL::FontFace_c::getDescender

(

void

)

const

Get the descender of the font with multiplication factor of 64.

Returns

descender of font

FT_FaceRec_* STLL::FontFace_c::getFace ( void  ) const

inline

Get the FreeType structure for this font.

This is required for example for harfbuzz. You normally don't need this when using STLL

uint32_t STLL::FontFace_c::getHeight

(

void

)

const

Get the height of the font with multiplication factor of 64.

Returns

height of font

const internal::FontFileResource_c& STLL::FontFace_c::getResource ( void  ) const

inline

get the font resource that was used to create this font

uint32_t STLL::FontFace_c::getSize ( void  ) const

inline

get the size of the font

int32_t STLL::FontFace_c::getUnderlinePosition

(

void

)

const

Get the underline position of the font with multiplication factor of 64.

Returns

centre position of the underline relative to baseline

int32_t STLL::FontFace_c::getUnderlineThickness

(

void

)

const

Get the underline thickness of the font with multiplication factor of 64.

Returns

thickness around the underline position

GlyphSlot_c STLL::FontFace_c::renderGlyph	(	glyphIndex_t	glyphIndex,
		SubPixelArrangement	sp
	)

render a glyph of this font

Parameters

glyphIndex	the index of the glyph to render (take it from the layout)
sp	the requested sub-pixel arrangement to apply to the rendering

Returns

a pointer to the FreeType glyph slot record, see FreeType documentation

Note

glyphs are always rendered unhinted 8-bit FreeType bitmaps
