Member Function Documentation

CharBitmap * FontFile::get_char (  int  n  )  const [inline]

Returns the nth character (glyph) read from the font. Definition at line 121 of file fontFile.I.

double FontFile::get_dpi (   )  const [inline]

Returns the resolution of the rasterized font in dots per inch. This is mainly useful for user information; use get_vppp() and get_hppp() for more precises measurements. Definition at line 55 of file fontFile.I. References _vppp.

double FontFile::get_ds (   )  const [inline]

Returns the designed size of the font in points. This is the basic height of a line of text in the given font. Definition at line 36 of file fontFile.I. References _vppp, and INLINE.

double FontFile::get_hppp (   )  const [inline]

Returns the horizontal pixels per point of the rasterized font characters. This is the number of pixels wide each bitmap characters is per point of font. Definition at line 93 of file fontFile.I.

int FontFile::get_num_chars (   )  const [inline]

Returns the number of characters (glyphs) read from the font. Definition at line 108 of file fontFile.I.

double FontFile::get_vppp (   )  const [inline]

Returns the vertical pixels per point of the rasterized font characters. This is the number of pixels high each bitmap characters is per point of font. Definition at line 74 of file fontFile.I. References _chars, and INLINE.

virtual bool FontFile::read (  const Filename &  filename, bool  extract_all, const string &  extract_only )  [pure virtual]

Implemented in PkFontFile.

void FontFile::sort_chars_by_height (   )

Sorts the array of characters in the font as returned by get_char() so that the tallest ones appear first in the list. Definition at line 77 of file fontFile.cxx.
