% Type 42 font support code.
% Here are the BuildChar and BuildGlyph implementation for Type 42 fonts.
% The names %Type42BuildChar and %Type42BuildGlyph are known to the
% interpreter. The real work is done in an operator:
% <font> <code|name> <name> <glyphindex> .type42execchar -
/.type42build % <font> <code|name> <name> .type42build -
{ 2 index begin
dup CharStrings exch .knownget not
{ 2 copy eq { exch pop /.notdef exch } if
QUIET not
{ (Substituting .notdef for ) print
=string cvs print ( in the font ) print
1 index /FontName get = flush
}
{ pop }
ifelse
/.notdef CharStrings /.notdef get
} if
end .type42execchar
} bind def
(%Type42BuildChar) cvn % <font> <code> %Type42BuildChar -
{ 1 index /Encoding get 1 index get //.type42build exec
} bind executeonly def
(%Type42BuildGlyph) cvn % <font> <name> %Type42BuildGlyph -
{ dup //.type42build exec
} bind executeonly def
currentdict /.type42build .undef
% Register the font type for definefont.
buildfontdict 42
{ % check for bogus sfnts -- this happens in Genoa FTS 421-01.ps
dup /sfnts get 0 get length 14 lt { % smallest valid sfnts is 14 bytes
% HACK: Add a BuildGlyph and make this a Type 3 font instead
dup /FontType 3 put
dup /BuildGlyph {
1 index /CharStrings get exch 2 copy known not { pop /.notdef } if get exec
} bind put
//.buildfont3 exec
