Appendix A - Picture OpcodesThis appendix describes picture opcodes, which are numbers used by the
DrawPictureprocedure to determine what object to draw or what mode to change for subsequent drawing. Your application generally should not read or write picture opcodes directly but should instead use QuickDraw routines (described in the chapter "Pictures" in this book) for generating and processing the opcodes. Picture opcodes are listed here for your application's debugging purposes.
Picturerecord (described in the chapter "Pictures") begins with a
picSizefield and a
picFramefield, followed by a variable amount of picture definition data in the form of opcodes. The first opcode in any picture must be the version opcode, followed by the version number of the picture.
