virtual int MGD::FONT::DrawGlyph (  MGD::CONTEXT *  context, double  dx, double  dy, double  baseangle, const STRINGDATA &  string, int  n )  [pure virtual]

virtual int MGD::FONT::DrawGlyph (  MGD::CONTEXT *  context, double  dx, double  dy, double  baseangle, const UNICODE *  ucstr, MGD::FONT::MODE  mode )  [pure virtual]

virtual int MGD::FONT::GetFontMetrics (  MGD::CONTEXT *  context, MGD::FONTINFO &  fontinfo )  [pure virtual]

const UNICODE* MGD::FONT::GetFontName (   )  const [inline]

Definition at line 699 of file mgd2.h.

virtual MGD::FONT::FONTTYPE MGD::FONT::GetFontType (   )  const [pure virtual]

virtual int MGD::FONT::GetGlyphExtents (  MGD::CONTEXT *  context, const double &  dx, const double &  dy, const double &  baseangle, UNICODE  ch, DRECT2D &  extents, MGD::FONT::MODE  mode )  [pure virtual]

virtual int MGD::FONT::GetGlyphMetrics (  MGD::CONTEXT *  context, UNICODE  ch, MGD::GLYPHINFO &  glyphinfo, MGD::FONT::MODE  mode )  [pure virtual]

virtual ERRVALUE MGD::FONT::GetGlyphOutline (  UINT16  GlyphIndex, INT32 *  NumContours, LPOLYGON **  Def, UINT32  FontFlags )  [inline, virtual]

Get the outline of a glyph. This only works for TrueType fonts, but the caller won't have access to the TrueType-derived MGD::FONT_TTF. So we make it virtual and let it return an error by default. We could easily implement it for OF fonts too if it was ever needed. Definition at line 713 of file mgd2.h.

UNICODE MGD::FONT::GetInitChar (   )  const [inline]

Definition at line 722 of file mgd2.h.

UNICODE MGD::FONT::GetLastChar (   )  const [inline]

Definition at line 727 of file mgd2.h.

UNICODE MGD::FONT::GetNULLChar (   )  const [inline]

Definition at line 732 of file mgd2.h.

UNICODE MGD::FONT::GetNumGlyphs (   )  const [inline]

Definition at line 737 of file mgd2.h.

virtual bool MGD::FONT::IsEmbeddable (   )  const [pure virtual]

virtual double MGD::FONT::NextPosition (  MGD::CONTEXT *  context, double *  retx, double *  rety, double  baseangle, const STRINGDATA &  string, int  n, double  SpaceExtra = 0.0, double  GlyphExtra = 0.0 )  [pure virtual]

Parameters: SpaceExtra  Extra pixels per space to insert

ERRVALUE MGD::FONT::ReadTTF (  const UNICODE *  name, SIMPLE_ARRAY< UINT8 > &  data )  [static]

Read a TrueType font into memory. The "name" parameter is expected to be the filename, minus the path or extention. The FaceNum parameter is for TrueType Collections (ttc). A ttc file contains multiple ttfs Since TrueType fonts are embeded in resource files on the Macintosh (even in OS X), a simple "filename" isn't all that useful. This function handles reading the whole thing.

virtual int MGD::FONT::UCtoGID (  MGD::CONTEXT *  context, const UNICODE *  uc, MGD::STRINGDATA &  strdata )  [pure virtual]
