Basic Data Types

All metafile object specifications, including specifications of custom objects you define yourself, must use only the following basic data types. All other data types are defined from these. This means that your read and write code need only contain routines to read and write these data types.

If you are using Apple QuickDraw 3D, special metafile types corresponding to the first ten types below are declared in QD3DIO.h. (TQ3Uns8 , TQ3Uns16 , etc.) QD3DIO.h also contains prototypes for routines to read and write each of these types. Additional basic data types may be introduced in the future if the need for them arises.
