Constructor & Destructor Documentation

IMG_CanvasRGBA32Action::IMG_CanvasRGBA32Action ( GEN_String & name, IMG_CanvasRGBA32 * canvas, IMG_PixmapRGBA32 * undoPixmap, IMG_Rect & undoBnds )

Constructor. Parameters: name   The name of the action. canvas   The canvas on which the action should be applied (or undone). The action is supposed to be applied already. undoPixmap   The pixels of the canvas before the action was applied. This pixmap should have the same dimensions as the canvas itself. The pixels of this pixmap are copied and stored locally. undoBnds   The area in the canvas that is affected by this action.

IMG_CanvasRGBA32Action::~IMG_CanvasRGBA32Action ( ) [protected, virtual]

Destructor. The destructor is protected because actions should be deleted by decrementing the reference count.
