I am a bit-magnifying tool for editing small Forms directly on the display screen. I continue to be active until the user points outside of my viewing area.

	basic control sequence	top
	controlInitialize Sent by Controller|startUp as part of the standard control sequence, it provides a place in the standard control sequence for initializing the receiver (taking into account the current state of its model and view). It should be redefined in subclasses to perform some specific action.
	controlTerminate Provide a place in the standard control sequence for terminating the receiver (taking into account the current state of its model and view). It should be redefined in subclasses to perform some specific action.

	control defaults	top
	isControlActive In contrast to class Controller, only blue button but not yellow button events will end the receiver's control loop.
	redButtonActivity Determine which item in the red button pop-up menu is selected. If one is selected, then send the corresponding message to the object designated as the menu message receiver.

	initialize-release	top
	release Breaks the cycle between the receiver and its view. It is usually not necessary to send release provided the receiver's view has been properly released independently.

	menu messages	top
	accept The edited information should now be accepted by the view.
	cancel The edited informatin should be forgotten by the view.
	fileOut
	setColor: Set the color that the next edited dots of the model to be the argument, aSymbol. aSymbol can be any color changing message understood by a Form, such as white or black.

	view access	top
	view: Controller|view: and Controller|model: are sent by View|controller: in order to coordinate the links between the model, view, and controller. In ordinary usage, the receiver is created and passed as the parameter to View|controller: and the receiver's model and view links are set up automatically by the view.

	class initialization	top
	initialize The Bit Editor is the only controller to override the use of the blue button with a different pop-up menu. Initialize this menu.

	examples	top
	magnifyOnScreen Bit editing of an area of the display screen. User designates a rectangular area that is magnified by 8 to allow individual screens dots to be modified. red button is used to set a bit to black and yellow button is used to set a bit to white. Editor is not scheduled in a view. Original screen location is updated immediately. This is the same as FormEditor magnify.
	magnifyWithSmall Also try: BitEditor openOnForm: (Form extent: 32@32 depth: Display depth) BitEditor openOnForm: ((MaskedForm extent: 32@32 depth: Display depth) withTransparentPixelValue: -1)

	instance creation	top
	openOnForm: Create and schedule a BitEditor on the form aForm at its top left corner. Show the small and magnified view of aForm.
	openOnForm:at: Create and schedule a BitEditor on the form aForm at magnifiedLocation. Show the small and magnified view of aForm.
	openOnForm:at:scale: Create and schedule a BitEditor on the form aForm. Show the small and magnified view of aForm.
	openScreenViewOnForm:at:magnifiedAt:scale: Create and schedule a BitEditor on the form aForm. Show the magnified view of aForm in a scheduled window.

	private	top
	bitEdit:at:scale:remoteView: Create a BitEditor on aForm. That is, aForm is a small image that will change as a result of the BitEditor changing a second and magnified view of me. magnifiedFormLocation is where the magnified form is to be located on the screen. scaleFactor is the amount of magnification. This method implements a scheduled view containing both a small and magnified view of aForm. Upon accept, aForm is updated.
	buildColorMenu:colorCount: See BitEditor magnifyWithSmall.
	locateMagnifiedView:scale: Answer a rectangle at the location where the scaled view of the form, aForm, should be displayed.
