Auzug aus den Adobe® Supplement to the ISO 32000, BaseVersion: 1.7, ExtensionLevel: 3
Zitat: | Appendix C Implementation Limits
176. Acrobat viewers earlier than 5.0 use the PostScript save and restore operators rather than gsave
and grestore to implement q and Q, and are subject to a nesting limit of 12 levels.
177.In PDF versions earlier than PDF 1.6, the size of the default user space unit is fixed at 1 / 72 inch. In
Acrobat viewers earlier than version 4.0, the minimum allowed page size is 72 by 72 units in default
user space (1 by 1 inch); the maximum is 3240 by 3240 units (45 by 45 inches). In Acrobat versions 5.0
and later, the minimum allowed page size is 3 by 3 units (approximately 0.04 by 0.04 inch); the
maximum is 14,400 by 14,400 units (200 by 200 inches).
Beginning with PDF 1.6, the size of the default user space unit may be set with the UserUnit entry of
the page dictionary. Acrobat 7.0 supports a maximum UserUnit value of 75,000, which gives a
maximum page dimension of 15,000,000 inches (14,400 * 75,000 * 1 / 72). The minimum UserUnit
value is 1.0 (the default). |
