Patterns.nib
README file for the Pattern application. The Pattern application is intended to highlight patterns in a Display PostScript environment. Patterns are formally defined in Level 2 and will be supported by special operators. Applications can include emulations for Pattern handling that will work in Level 1 devices. The Pattern application contains these emulations. In addition, performance and tiling issues are demonstrated in the application. Below lies an annotated list of the files used in the application. PatternApp - A subclass of Application. Creates the window with the ScrollView, DocView and DrawingView. Provides the id's of the items in the Methods Panel (matrices, buttons, etc). DocView - A subclass of View. Serves as the DocView for the ScrollView. Makes the DrawingView a subview making it easier to size and scale the DrawingView. The Drawing View is resized whenever the user zooms into or out of the document. DrawingView - A subclass of View. The view that manages the drawing for a document. Contains three simple graphics, a filled rectangle, a stroked rectangle and a set of charcaters. Fill the graphics with the selected pattern with the selected number of cells and with the selected approach. Pattern - A subclass of Object. Roughly modeled after the Font object. Provides methods for creating and setting patterns. PSWpatterns.psw - PS Routines for turning patterns into Type 3 fonts. PSWsamples.m - PS Pattern dictionaries (CircleStar, Octagon, Brick, Weave). PSWpatternsdemos.psw - PS routines for drawing and compositing patterns. (Not recommended approaches) Topics of interest from the Pattern application: Displaying patterns as a Type 3 font (Pattern, PSWpatterns.psw) Locking the pattern to View space (Pattern, PSWpatterns.psw, DrawingView) Pattern Dictionaries (PSWsamples.psw) Scaling the view (DocView, DrawingView)
