Allocate a graphics context
PhGC_t *PgCreateGC( int unused );
ph
This function allocates a graphics context. A graphics context contains the entire draw state, including color, clipping, and current region.
If your application calls both Pg and Pt functions, you must provide one graphics context for the Pg functions and a separate context for the Pt functions. To do this, call PgSetGC() every time you switch from one API to the other. |
A pointer to a graphics context, or NULL if an error occurs.
