Abstract

Described is a mechanism of the font management if a program can not find the font shape which is desired by the program. Various kinds of font sets are avaliable from numbers of font vendors recently, because of the recent development of desktop publishing and word processing on personal computers. However, font vendors do not offer all font shapes which a program desires, especially, the technique, by which a user named "User Font Concept" can originally make the shape of a font, is permitted in Asian countries. Therefore, users have to make all user font shapes they desire which correspond to registered font set by themselves.

Virtual Font Management

      Described is a mechanism of the font management if a program
can not find the font shape which is desired by the program.  Various
kinds of font sets are avaliable from numbers of font vendors
recently, because of the recent development of desktop publishing and
word processing on personal computers.  However, font vendors do not
offer all font shapes which a program desires, especially, the
technique, by which a user named "User Font Concept" can originally
make the shape of a font, is permitted in Asian countries.
Therefore, users have to make all user font shapes they desire which
correspond to registered font set by themselves.

      Fig. 1 shows the example of the problem caused by the above
conventional situation.  Suppose a user newly installed a font set,
the "Installed Font" that does not have the user font set.  (The set
provides only the user font set for the "Base Font".) In this case,
the program can not display the new user font shape (or character) if
the program uses the "Installed Font" set.

      To solve the above problem, a new font management system,
VIRTUAL FONT MANAGEMENT (VFM), is suggested here.  The VFM has the
mechanism of font substitution that defines the relationship among
all font sets.  The same font class (ex.  Gothic type or not) or a
user's configuration would be considered for the keyword of the
substitution.

      Fig 2.  shows the example of this mechanism.  If a program
wants to...
