Detailed Description

Paints on a canvas.

Date:: 2002/12/11 14:26:22

Revision:: 1.31

vtkImageCanvasSource2D is a source that starts as a blank image. you may add to the image with two-dimensional drawing routines. It can paint multi-spectral images. This object is unusual because it is a data object itself and not a source.
