HitDetection.nib
README file for the HitDetection application. The HitDetection application is intended to highlight patterns in a Display PostScript environment. Below lies an annotated list of the files used in the application. DetectApp - 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). ScrollingView - A subclass of ScrollView. This view syncronizes the DrawingView with the offscreen buffers. 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 a single Bezier curver (represented in the form of a Bezier object). A grid can be drawn in the view and it can be scaled in or out in conjuction with the DocView. Bezier - A subclass of Object that contains the points locations for the Bezier and performs the hit detection operations. DrawingViewWraps.psw - PS Routines for turning patterns into Type 3 fonts. Topics of interest from the HitDetection application: Drawing a grid (DrawingView) Changing and moving a graphic object (DrawingView, Bezier) Using offscreen windows to buffer drawing (ScrollingView, DrawingView) Hit detection (DrawingView, Bezier) Scaling the view (DocView, DrawingView)
