Constructor

AreaAveragingScaleFilter

public AreaAveragingScaleFilter (int width, int height)

Parameters

width

Width of scaled image.

height

Height of scaled image.

Description

Constructs an AverageScaleFilter that scales the original image to the specified size.

Instance Methods

setHints

Overrides

ImageFilter.setHints(int)

Description

Gives this filter hints about how data will be delivered.

setPixels

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

Parameters

x

x-coordinate of top-left corner of pixel data delivered with this method call.

y

y-coordinate of top-left corner of pixel data delivered with this method call.

w
