Class ReplicateScaleFilter

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.

Field Summary
protected int	destHeight The height of the destination image.
protected int	destWidth The width of the destination image.
protected Object	outpixbuf
protected int[]	srccols
protected int	srcHeight The height of the source image.
protected int[]	srcrows
protected int	srcWidth The width of the source image.

Constructor Summary
	ReplicateScaleFilter(int width, int height)

Method Summary
void	setDimensions(int width, int height) An `ImageProducer` indicates the size of the image being produced using this method.
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).
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).
void	setProperties(Hashtable<?,?> props) An `ImageProducer` can set a list of properties associated with this image by using this method.

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.

Parameters: width the width of the image height the height of the 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).

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).

setProperties

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

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

Parameters: props the list of properties associated with this image
