#### 4.1.8.1 cgm font

The first part of a Computer Graphics Metafile, the metafile description, includes a font table. In the picture body, a font is designated by an index into this table. By default, this terminal generates a table with the following 35 fonts, plus six more with ‘italic‘ replaced by ‘oblique‘, or vice-versa (since at least the Microsoft Office and Corel Draw CGM import filters treat ‘italic‘ and ‘oblique‘ as equivalent):

          Helvetica
          Helvetica Bold
          Helvetica Oblique
          Helvetica Bold Oblique
          Times Roman
          Times Bold
          Times Italic
          Times Bold Italic
          Courier
          Courier Bold
          Courier Oblique
          Courier Bold Oblique
          Symbol
          Hershey/Cartographic_Roman
          Hershey/Cartographic_Greek
          Hershey/Simplex_Roman
          Hershey/Simplex_Greek
          Hershey/Simplex_Script
          Hershey/Complex_Roman
          Hershey/Complex_Greek
          Hershey/Complex_Script
          Hershey/Complex_Italic
          Hershey/Complex_Cyrillic
          Hershey/Duplex_Roman
          Hershey/Triplex_Roman
          Hershey/Triplex_Italic
          Hershey/Gothic_German
          Hershey/Gothic_English
          Hershey/Gothic_Italian
          Hershey/Symbol_Set_1
          Hershey/Symbol_Set_2
          Hershey/Symbol_Math
          ZapfDingbats
          Script
          15

The first thirteen of these fonts are required for WebCGM. The Microsoft Office CGM import filter implements the 13 standard fonts listed above, and also ’ZapfDingbats’ and ’Script’. However, the script font may only be accessed under the name ’15’. For more on Microsoft import filter font substitutions, check its help file which you may find here:

      C:\\Program Files\\Microsoft Office\\Office\\Cgmimp32.hlp

and/or its configuration file, which you may find here:

      C:\\Program Files\\Common Files\\Microsoft Shared\\Grphflt\\Cgmimp32.cfg

In the ‘set term‘ command, you may specify a font name which does not appear in the default font table. In that case, a new font table is constructed with the specified font as its first entry. You must ensure that the spelling, capitalization, and spacing of the name are appropriate for the application that will read the CGM file. (Gnuplot and any MIL-D-28003A compliant application ignore case in font names.) If you need to add several new fonts, use several ‘set term‘ commands.

Example:

          set terminal cgm 'Old English'
          set terminal cgm 'Tengwar'
          set terminal cgm 'Arabic'
          set output 'myfile.cgm'
          plot ...
          set output

You cannot introduce a new font in a ‘set label‘ command.
