Deprecated.

Constructs a a new model for a multi level source. The number of levels is computed by getLevelCount(int, int). The image bounds are computed by getModelBounds(java.awt.geom.AffineTransform, int, int).

Parameters:

imageToModelTransform - The affine transformation from image to model coordinates.

width - The width of the image in pixels at level zero.

height - The height of the image in pixels at level zero.
