public class AreaAverageScaleFilter
extends ReplicatingScaleFilter

Area-averaging scale filter based on java.awt.image.AreaAveragingScaleFilter, but more robust.

Fields inherited from class com.sun.jimi.core.filters.ReplicatingScaleFilter
`destHeight, destWidth, outpixbuf, srccols, srcHeight, srcrows, srcWidth`

Fields inherited from class java.awt.image.ImageFilter
`consumer`

Constructor Summary
`AreaAverageScaleFilter(int width, int height)` Constructs an AreaAverageScaleFilter that scales the pixels from its source Image as specified by the width and height parameters.

Method Summary
`void` | `setHints(int hints)` Detect if the data is being delivered with the necessary hints to allow the averaging algorithm to do its work.
`void` | `setPixels(int x, int y, int w, int h, java.awt.image.ColorModel model, byte[] pixels, int off, int scansize)` Combine the components for the delivered byte pixels into the accumulation arrays and send on any averaged data for rows of pixels that are complete.
`void` | `setPixels(int x, int y, int w, int h, java.awt.image.ColorModel model, int[] pixels, int off, int scansize)` Combine the components for the delivered int pixels into the accumulation arrays and send on any averaged data for rows of pixels that are complete.

Constructor Detail

### AreaAverageScaleFilter

    public AreaAverageScaleFilter(int width,
                                  int height)

  Constructs an AreaAverageScaleFilter 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

Method Detail

### setHints

    public void setHints(int hints)

  Detect if the data is being delivered with the necessary hints to allow the averaging algorithm to do its work.
  Overrides:
    setHints in class java.awt.image.ImageFilter
  See Also:
    `ImageConsumer.setHints(int)`

### setPixels

    public void setPixels(int x,
                          int y,
                          int w,
                          int h,
                          java.awt.image.ColorModel model,
                          byte[] pixels,
                          int off,
                          int scansize)

  Combine the components for the delivered byte pixels into the accumulation arrays and send on any averaged data for rows of pixels that are complete. If the correct hints were not specified in the setHints call then relay the work to our superclass which is capable of scaling pixels regardless of the delivery hints.
  Overrides:
    setPixels in class ReplicatingScaleFilter
  See Also:
    `ReplicateScaleFilter`

### setPixels

    public void setPixels(int x,
                          int y,
                          int w,
                          int h,
                          java.awt.image.ColorModel model,
                          int[] pixels,
                          int off,
                          int scansize)

  Combine the components for the delivered int pixels into the accumulation arrays and send on any averaged data for rows of pixels that are complete. If the correct hints were not specified in the setHints call then relay the work to our superclass which is capable of scaling pixels regardless of the delivery hints.
  Overrides:
    setPixels in class ReplicatingScaleFilter

    `ReplicateScaleFilter`
