CHAPTER 2
LaserWriter 16/600 PS Software
Resource Categories 67
Resource Categories 2
In PostScript Language Level 2, PostScript objects such as fonts, patterns, and filters can
be managed as open-ended collections of resources grouped into categories. A resource
is requested by resource category and name. If the resource does not reside in virtual
memory, the resource management mechanism loads it from an external source, such as
a disk, a ROM cartridge, or a network file server. The PostScript Language Reference
Manual, second edition discusses named resources in detail.
There are several groups of resources:
■ New resources in the regular resource categories can be added. These include such
items as font and pattern resources (Table 2-23).
■ Categories of implicit resources represent built-in capabilities of the LaserWriter 16/
600 PS interpreter. For example, the FormType category indicates that the interpreter
understands Type 1 only (Table 2-27).
■ Some resources are used to define new categories (Table 2-28).
