QuickDrawViewer: A Mac OS X utility to visualise QuickDraw (PICT) files

The article discusses the creation of QuickDrawViewer, a Mac OS X utility designed to visualize QuickDraw (PICT) files. The program was developed as a Swift programming exercise and aims to render QuickDraw images on modern Mac OS X screens. QuickDraw was the graphical language of the original Macintosh, but support for these files has been declining with newer versions of Mac OS X. QuickDrawViewer also supports QuickTime and MacPaint images by converting them into QuickDraw at load time. The utility consists of four main parts, including libraries for parsing QuickDraw files and rendering into a CoreGraphics context, as well as a Swift-UI application for displaying the images. The article also mentions some unsupported QuickDraw features and provides a small conversion command-line tool and a Python script for converting QuickDraw data into PICT files.
