AreaAveragingScaleFilter

Name

Description

The AreaAveragingScaleFilter class scales an image using a simple smoothing algorithm.

Class Definition

public class java.awt.image.AreaAveragingScaleFilter extends java.awt.image.ReplicateScaleFilter {
 // Constructor public AreaAveragingScaleFilter (int width, int height); // Instance Methods public void setHints (int hints);
public void setPixels (int x, int y, int w, int h, ColorModel model, byte[] pixels, int off, int scansize);
public void setPixels (int x, int y, int w, int h, ColorModel model, int[] pixels, int off, int scansize);

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

public void setHints (int hints)

• Parameters
• • hints
  • Flags indicating how data will be delivered.
• 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
  • Width of the rectangle of pixel data delivered with this method call.
  • h
  • Height of the rectangle of pixel data delivered with this method call.
  • model
  • Color model of image data.
  • pixels
  • Image data.
  • off
  • Offset from beginning of the pixels array.
  • scansize
  • Size of each line of data in pixels array.
• Overrides
• ReplicateScaleFilter.setPixels(int, int, int, int, ColorModel, byte[], int, int)
• Description
• Receives a rectangle of image data from the ImageProducer; scales these pixels and delivers them to any ImageConsumers.
