Font Formats

There are many different font formats. The extension lets you determine the font type.

• PostScript Type 1 Fonts , which are also known as Adobe Type Manager (ATM) fonts, Type 1, and outline fonts, contain information in outline form that allows a PostScript printer or ATM to generate fonts of any size. Most of these fonts also contain hints that allow fonts to be rendered more readable at a low resolution or a small type size.

• Bitmap Fonts contain a picture of the font at a specific size that has been optimized to look good at that specific size. If the font is scaled larger or smaller, the quality may degrade. On the other hand, bitmap fonts display quickly.

Location of Fonts on the System

Fonts are located at:

/usr/openwin/lib/locale/iso_8859_x/X11/fonts/X11/Type1/afm

or

/usr/openwin/lib/locale/iso_8859_x/X11/fonts/X11/75dpi

Adding and Removing Font Packages

To manually add font packages to the system:

1. Always add the required font packages before the optional font packages.

2. When you are removing font packages from the system, remove the optional font packages first.

You must follow this procedure to add or remove fonts. The class action scripts in the font packages depend on this for proper function. The optional font packages contain scripts that concatenate information onto the required font packages that are already resident on the system. If the required font packages are not there, problems may occur.
