Detailed Description

PostScript graphical backend.

PostScript text uses vectorial fonts when using the FLTK standard fonts and the latin alphabet or a few other characters listed in the following table. The latin alphabet means all unicode characters between U+0020 and U+017F, or, in other words, the ASCII, Latin-1 Supplement and Latin Extended-A charts.

All other unicode characters or all other fonts (FL_FREE_FONT and above) are output as a bitmap.
FLTK standard fonts are output using the corresponding PostScript standard fonts.

const char* Fl_PostScript_Graphics_Driver::class_name ( )
inlinevirtual

Returns the name of the class of this object.

Use of the class_name() function is discouraged because it will be removed from future FLTK versions.

The class of an instance of an Fl_Device subclass can be checked with code such as:

if ( instance->class_name() == Fl_Printer::class_id ) { ... }

Reimplemented from Fl_Graphics_Driver.

)
virtual
int Fl_PostScript_Graphics_Driver::clocale_printf ( const char *  format,

Shields output PostScript data from modifications of the current locale.

It typically avoids PostScript errors caused if the current locale uses comma instead of dot as "decimal point".

Parameters
