vtkWindowToImageFilter

Section: Visualization Toolkit Rendering Classes

Usage

vtkWindowToImageFilter provides methods needed to read the data in a vtkWindow and use it as input to the imaging pipeline. This is useful for saving an image to a file for example. The window can be read as either RGB or RGBA pixels; in addition, the depth buffer can also be read. RGB and RGBA pixels are of type unsigned char, while Z-Buffer data is returned as floats. Use this filter to convert RenderWindows or ImageWindows to an image format.

To create an instance of class vtkWindowToImageFilter, simply invoke its constructor as follows
