Class ReplicateScaleFilter

java.lang.Object

java.awt.image.ImageFilter

java.awt.image.ReplicateScaleFilter

All Implemented Interfaces:

ImageConsumer, Cloneable

Direct Known Subclasses:

AreaAveragingScaleFilter

public class ReplicateScaleFilter
extends ImageFilter

This filter should be used for fast scaling of images where the result does not need to ensure straight lines are still straight, etc. The exact method is not defined by Sun but some sort of fast Box filter should probably be correct.
Currently this filter does nothing and needs to be implemented.

Method Detail

setDimensions

public void setDimensions(int width,
                 int height)

An ImageProducer indicates the size of the image being produced using this method. A filter can override this method to intercept these calls from the producer in order to change either the width or the height before in turn calling the consumer's setDimensions method.

Specified by:

setDimensions in interface ImageConsumer

Overrides:

setDimensions in class ImageFilter

Parameters:

width - the width of the image

height - the height of the image

setProperties

public void setProperties(Hashtable<?,?> props)

An ImageProducer can set a list of properties associated with this image by using this method.

Specified by:

setProperties in interface ImageConsumer

Overrides:

setProperties in class ImageFilter

Parameters:

props - the list of properties associated with this image

setPixels

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

This function delivers a rectangle of pixels where any pixel(m,n) is stored in the array as a byte at index (n * scansize + m + offset).

Specified by:

setPixels in interface ImageConsumer

Overrides:

setPixels in class ImageFilter

Parameters:

x - the x coordinate of the rectangle

y - the y coordinate of the rectangle

w - the width of the rectangle

h - the height of the rectangle

model - the ColorModel used to translate the pixels

pixels - the array of pixel values

offset - the index of the first pixels in the pixels array

scansize - the width to use in extracting pixels from the pixels array

setPixels

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

This function delivers a rectangle of pixels where any pixel(m,n) is stored in the array as an int at index (n * scansize + m + offset).

Specified by:

setPixels in interface ImageConsumer

Overrides:

setPixels in class ImageFilter

Parameters:

x - the x coordinate of the rectangle

y - the y coordinate of the rectangle

w - the width of the rectangle

h - the height of the rectangle

model - the ColorModel used to translate the pixels

pixels - the array of pixel values

offset - the index of the first pixels in the pixels array

scansize - the width to use in extracting pixels from the pixels array
