Graphics Function: Gets the current font characteristics.

Module: USE DFLIB

Syntax

result = GETFONTINFO (font)

font
(Output) Derived type FONTINFO. Set of characteristics of the current font. The FONTINFO derived type is defined in DFLIB.F90 (in the \DF98\INCLUDE subdirectory) as follows:

TYPE FONTINFO
  INTEGER(4) type        ! 1 = truetype, 0 = bit map
  INTEGER(4) ascent      ! Pixel distance from top to
                         !   baseline
  INTEGER(4) pixwidth    ! Character width in pixels,
                         !   0=proportional
  INTEGER(4) pixheight   ! Character height in pixels
  INTEGER(4) avgwidth    ! Average character width in
                         !   pixels
  CHARACTER(32)xfacename ! Font name
  LOGICAL(1) italic      ! .TRUE. if current font
                         !   formatted italic
  LOGICAL(1) emphasized  ! .TRUE. if current font
                         !   formatted bold
  LOGICAL(1) underline   ! .TRUE. if current font
                         !   formatted underlined
END TYPE FONTINFO

Results:

The result is of type INTEGER(2). The result is zero if successful; otherwise, -1.

You must initialize fonts with INITIALIZEFONTS before calling any font-related function, including GETFONTINFO.
