XEROX DOCUPRINT NPS GUIDE TO USING PAGE DESCRIPTION LANGUAGES 2-5
• Font characters are cached so that multiple uses of a visual
element in a document are rendered quicker if the elements are
taken from a font than if they are read from supplementary files.
• Including graphic images is easier when creating the document.
Producing Type 1 fonts for use with DocuPrint
Third-party software for font editing and creation is available for most
popular personal computing systems. With these programs, you can
edit or produce outlines from a bitmap obtained by scanning existing
line art.
Each graphical item that is referenced must be assigned to a
character code in a font. You can incorporate many graphic elements
in a single font by assigning each element to a different character
code, or you can place each item in its own font.
Once created, you must save Type 1 fonts on an MS-DOS diskette
as files with the .pfb extension. You can then load the fonts from
diskette onto a DocuPrint system using the administrator Install
Fonts From Floppy command.
Using a Type 1 font in a document
When you create a document using a standard document editor, you
enter the character that refers to the graphic image you want, assign
the appropriate font to it, and size and place it to fit the document. If
you are using Adobe Type Manager, the image is scaled and
displayed.
The PostScript driver of the document editor selects the font using
the PostScript operator findfont and scales the font using scalefont.
Once the font is installed as current by the setfont operator, any
show of a character images the figure associated with that character
code.
For example, you can create a font containing a corporate logo,
assigned to the character a. The following PostScript example shows
how the specific size of the logo font is assigned a name within a
master, and how the logo is placed on a page.
