property OnPaintStage: TPaintStageEvent;
type TPaintStageEvent = procedure(Sender: TObject; Dest: TBitmap32; StageNum: Cardinal) of object;
An event, called by the control while it repaints itself. By default, TCustomImage32 does not generate OnPaintStage events, but this can be changed by adding PST_CUSTOM paint stages.
In the event handler, do not paint to Buffer directly, use the passed Dest parameter instead.
