3D Graphics Programming with QuickDraw 3D 1.5.4

Managing Pixmap Draw Contexts

QuickDraw 3D provides routines that you can use to create and manipulate pixmap draw contexts.

Q3PixmapDrawContext_New

You can use the Q3PixmapDrawContext_New function to create a new pixmap draw context.



 
TQ3DrawContextObject Q3PixmapDrawContext_New (

                     const TQ3PixmapDrawContextData *contextData);

contextData: A pointer to a pixmap draw context data structure.

DESCRIPTION

The Q3PixmapDrawContext_New function returns, as its function result, a new draw context object having the characteristics specified by the contextData parameter.

Q3PixmapDrawContext_GetPixmap

You can use the Q3PixmapDrawContext_GetPixmap function to get the pixmap associated with a pixmap draw context.



 
TQ3Status Q3PixmapDrawContext_GetPixmap (

                     TQ3DrawContextObject drawContext, 

                     TQ3Pixmap *pixmap);

drawContext: A pixmap draw context object.
pixmap: On exit, a pointer to a pixmap.

DESCRIPTION

The Q3PixmapDrawContext_GetPixmap function returns, in the pixmap parameter, a pointer to the pixmap currently associated with the draw context specified by the drawContext parameter.

Q3PixmapDrawContext_SetPixmap

You can use the Q3PixmapDrawContext_SetPixmap function to set the pixmap associated with a pixmap draw context.



 
TQ3Status Q3PixmapDrawContext_SetPixmap (

                     TQ3DrawContextObject drawContext, 

                     const TQ3Pixmap *pixmap);

drawContext: A pixmap draw context object.
pixmap: A pointer to a pixmap.

DESCRIPTION

The Q3PixmapDrawContext_SetPixmap function sets the pixmap associated with the draw context specified by the drawContext parameter to the pixmap specified by the pixmap parameter.
