Examples of java.awt.image.ReplicateScaleFilter

java.awt.image.ReplicateScaleFilter
An ImageFilter class for scaling images using the simplest algorithm. This class extends the basic ImageFilter Class to scale an existing image and provide a source for a new image containing the resampled image. The pixels in the source image are sampled to produce pixels for an image of the specified size by replicating rows and columns of pixels to scale up or omitting rows and columns of pixels to scale down.
It is meant to be used in conjunction with a FilteredImageSource object to produce scaled versions of existing images. Due to implementation dependencies, there may be differences in pixel values of an image filtered on different platforms. @see FilteredImageSource @see ImageFilter @version 1.21 11/17/05 @author Jim Graham
