Clip Data Structure

You specify a clipping region (for example, when creating a new draw context with the QADrawContextNew function) by filling in a clip data structure, defined by the TQAClip data type. The clipping region determines which pixels are drawn to a device.



 
typedef struct TQAClip {

    TQAClipType                         clipType;

    TQAPlatformClip                     clip;

} TQAClip;

clipType: The clip type. See "Clip Types" for the values you can assign to this field.
clip: A platform clip data structure.
