Detailed Description

2D widget for placing and manipulating a logo

This class provides support for interactively displaying and manipulating a logo. Logos are defined by an image; this widget simply allows you to interactively place and resize the image logo. To use this widget, simply create a vtkLogoRepresentation (or subclass) and associate it with the vtkLogoWidget.
