Function Documentation

int mt_FontId2Name (  APPvar *  app, int  id, char *  name )

convert an id-font in a font name Parameters: app  application descriptor id  font identificator name  name font associated to id, it should be a 64-byte buffer. Returns: 0 (success) or -1 if the font is not found The identificator font is an integer value which identify in a unique way a font. This fonction finds the font name associated to a font identificator. The fonction needs a font manager to work correctly See also: mt_FontName2Id()

int mt_FontName2Id (  APPvar *  app, char *  name )

convert a font name in a id-font Parameters: app  application descriptor name  font name Returns: font id or -1 if font does not exist The identificator font is an integer value which identify in a unique way a font. This fonction finds the id-font associated to a font name. The fonction needs a font manager to work correctly. See also: mt_FontId2Name()

int mt_VqtName (  APPvar *  app, int  elem, char *  name )

emulate vqt_name when GDOS not detected Parameters: app  application descriptor elem  same as elem paramter of VDI function vqt_name() name  same as name paramter of VDI function vqt_name() Returns: same as return value of VDI function vqt_name() mt_VqtName() has the same effect than vqt_name() except it works even if a font driver is not present in memory. The condition is a valid FONTID file exists in the $ETC directory.

int mt_VqtXname (  APPvar *  app, int  id, int  _index, char *  name, int *  fl )

customized function that sumary VDI functions vqt_extname, vqt_xfntinfo and vqt_fontheader Parameters: app  application descriptor id  font-ID _index  same as 2nd parameter of VDI functions vqt_name() or vqt_extname() name  TODO fl  is a bitmap variable wich is a OR of the following flags: FNT_OUTLINE : vectorial font (bitmap font if unset) FNT_MONO : monospaced font (proportional font if unset) FNT_SPEEDO : vectorial font type is SPEEDO FNT_TRUETYPE : vectorial font type is True Type FNT_TYPE1 : vectorial font type is PostScript type 1 Returns: font ID or -1 in case of error

int mt_VstFont (  APPvar *  app, int  id )

emulate vst_font() Parameters: app  application descriptor id  same as id paramter of VDI function vst_font() Returns: same as return value of VDI function vst_font()

int mt_VstLoadFonts (  APPvar *  app, int  res )

emulate vst_load_fonts() when GDOS is not detected Parameters: app  application descriptor res  same as res paramter of VDI function vst_load_fonts() Returns: same as return value of VDI function vst_load_fonts()

void mt_VstUnloadFonts (  APPvar *  app, int  res )

emulate vst_unload_fonts() when GDOS is not detected Parameters: app  application descriptor res  same as res paramter of VDI function vst_unload_fonts()

int vqt_extname (  int  handle, int  index, char *  name, int *  speedo, INT16 *  format, INT16 *  flags )

utility function based on NVDI4 vqt_ext_name binding Parameters: handle,index,name,format,flags  see VDI function vqt_ext_name() speedo  will contain the flag name[32] returned by the VDI function vqt_ext_name() Returns: see VDI function vqt_ext_name() the main change is the extra parameter speedo will contain name[32], and name[32] will be zero-ed (so that name[] is now a standard C string with a null byte at the end)
