PostScript::Resources - module to fetch data from Unix PostScript Resource '
my $rsc = new PostScript::Resources (options); print STDOUT $rsc->FontAFM ("Times-Roman"), "\n";
This package allows Unix font resource files, so called '
.upr' files, to be read and parsed.
The constructor will initialise the PostScript resource context by loading all resource files.
path is a colon-separated list of locations where resource files are kept. It defaults to the value of the environment variable
PSRESOURCEPATH, which defaults to '
Two adjacent colons in the path represent the list of default places in which a component looks for resources. This is also the default value for users who have not installed private resources. Users with private resources should end the path with a double colon if they want their resources to override the system defaults, or begin it with a double colon if they don't want to override system defaults.
On Unix systems, resource files end with the suffix '
.upr' (for Unix PostScript resources). The principal resource file in a directory is named '
If the first line of a principal resource file is '
PS-Resources-Exclusive-1.0', only this file will be loaded and processing continues with the next entry from the path.
If, however, the first line of the principal resource file is '
PS-Resources-1.0', or if there is no such file, all files in the directory with the suffix '
.upr' will be loaded.
The standard locations for resource files.
How errors must be handled.
Invalid entries in the file are always reported unless the error handling strategy is set to 'ignore'.
Prints verbose info if value is true.
Prints tracing info if value is true. trace' and 'Implies 'verbose'.
Prints debugging info if value is true. Implies 'trace' and 'verbose'.
Each of these methods can return
undef if the corresponding information could not be found in the file.
The name of the Adobe Font Metrics (.afm) file for the named font.
The name of the PostScript Font program for the named font.
The list of directories where resource files are kept. Semantics are as defined in appendix A of Display PostScript Toolkit for X, Adobe Technical Note
Only FontAFM and FontOutline resources are implemented. All other resource sections are ignored.
All info is loaded in memory structures. This is okay for small files or if several lookups are done on the same file.
Backslash escape processing is not yet implemented, except for the handling of line continuation.
This module is intended to be used on Unix systems only. Your mileage on other platforms may vary.
