public class ReplicateScaleFilter
extends ImageFilter

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.

##

ReplicateScaleFilter(int, int)
  Constructs a ReplicateScaleFilter that scales the pixels from its source Image as specified by the width and height parameters.

##

setDimensions(int, int)
  Override the dimensions of the source image and pass the dimensions of the new scaled size to the ImageConsumer.
setPixels(int, int, int, int, ColorModel, byte[], int, int)
  Choose which rows and columns of the delivered byte pixels are needed for the destination scaled image and pass through just those rows and columns that are needed, replicated as necessary.
setPixels(int, int, int, int, ColorModel, int[], int, int)
  Choose which rows and columns of the delivered int pixels are needed for the destination scaled image and pass through just those rows and columns that are needed, replicated as necessary.
setProperties(Hashtable)
  Passes along the properties from the source object after adding a property indicating the scale applied.

ReplicateScaleFilter

      public ReplicateScaleFilter(int width,
                                  int height)

  Constructs a ReplicateScaleFilter that scales the pixels from its source Image as specified by the width and height parameters.

  Parameters:
    width - the target width to scale the image
    height - the target height to scale the image

##

setProperties

      public void setProperties(Hashtable props)

  Passes along the properties from the source object after adding a property indicating the scale applied.

  Overrides:
    setProperties in class ImageFilter

setDimensions

      public void setDimensions(int w,
                                int h)

  Override the dimensions of the source image and pass the dimensions of the new scaled size to the ImageConsumer.

  Overrides:
    setDimensions in class ImageFilter

                            int scansize)

  Choose which rows and columns of the delivered byte pixels are needed for the destination scaled image and pass through just those rows and columns that are needed, replicated as necessary.

  Overrides:
    setPixels in class ImageFilter
