      java.awt.image.RGBImageFilter

RGBImageFilter
abstract public class RGBImageFilter extends ImageFilter (Code)
This class provides an easy way to create an ImageFilter which modifies the pixels of an image in the default RGB ColorModel. It is meant to be used in conjunction with a FilteredImageSource object to produce filtered versions of existing images. It is an abstract class that provides the calls needed to channel all of the pixel data through a single method which converts pixels one at a time in the default RGB ColorModel regardless of the ColorModel being used by the ImageProducer. The only method which needs to be defined to create a useable image filter is the filterRGB method. Here is an example of a definition of a filter which swaps the red and blue components of an image:
 class RedBlueSwapFilter extends RGBImageFilter {
 public RedBlueSwapFilter() {
 // The filter's operation does not depend on the
 // pixel's location, so IndexColorModels can be
 // filtered directly.
 canFilterIndexColorModel = true;
 }
 public int filterRGB(int x, int y, int rgb) {
 return ((rgb & 0xff00ff00)
 | ((rgb & 0xff0000) >> 16)
 | ((rgb & 0xff) << 16));
 }
 }

Field Summary
protected  booleancanFilterIndexColorModel
     This boolean indicates whether or not it is acceptable to apply the color filtering of the filterRGB method to the color table entries of an IndexColorModel object in lieu of pixel by pixel filtering.
protected  ColorModelnewmodel
    
protected  ColorModelorigmodel
    


Method Summary
public  IndexColorModelfilterIndexColorModel(IndexColorModel icm)
     Filters an IndexColorModel object by running each entry in its color tables through the filterRGB function that RGBImageFilter subclasses must provide.
abstract public  intfilterRGB(int x, int y, int rgb)
     Subclasses must specify a method to convert a single input pixel in the default RGB ColorModel to a single output pixel.
public  voidfilterRGBPixels(int x, int y, int w, int h, int pixels, int off, int scansize)
     Filters a buffer of pixels in the default RGB ColorModel by passing them one by one through the filterRGB method.
public  voidsetColorModel(ColorModel model)
     If the ColorModel is an IndexColorModel, and the subclass has set the canFilterIndexColorModel flag to true, we substitute a filtered version of the color model here and wherever that original ColorModel object appears in the setPixels methods.
public  voidsetPixels(int x, int y, int w, int h, ColorModel model, byte pixels, int off, int scansize)
     If the ColorModel object is the same one that has already been converted, then simply passes the pixels through with the converted ColorModel.
public  voidsetPixels(int x, int y, int w, int h, ColorModel model, int pixels, int off, int scansize)
     If the ColorModel object is the same one that has already been converted, then simply passes the pixels through with the converted ColorModel, otherwise converts the buffer of integer pixels to the default RGB ColorModel and passes the converted buffer to the filterRGBPixels method to be converted one by one.
public  voidsubstituteColorModel(ColorModel oldcm, ColorModel newcm)
     Registers two ColorModel objects for substitution.

Field Detail
canFilterIndexColorModel
protected boolean canFilterIndexColorModel(Code)
This boolean indicates whether or not it is acceptable to apply the color filtering of the filterRGB method to the color table entries of an IndexColorModel object in lieu of pixel by pixel filtering. Subclasses should set this variable to true in their constructor if their filterRGB method does not depend on the coordinate of the pixel being filtered.
See Also:   RGBImageFilter.substituteColorModel
See Also:   RGBImageFilter.filterRGB
See Also:   IndexColorModel



newmodel
protected ColorModel newmodel(Code)



origmodel
protected ColorModel origmodel(Code)





Method Detail
filterIndexColorModel
public IndexColorModel filterIndexColorModel(IndexColorModel icm)(Code)
Filters an IndexColorModel object by running each entry in its color tables through the filterRGB function that RGBImageFilter subclasses must provide. Uses coordinates of -1 to indicate that a color table entry is being filtered rather than an actual pixel value.
Parameters:
  icm - the IndexColorModel object to be filtered a new IndexColorModel representing the filtered colors



filterRGB
abstract public int filterRGB(int x, int y, int rgb)(Code)
Subclasses must specify a method to convert a single input pixel in the default RGB ColorModel to a single output pixel.
See Also:   ColorModel.getRGBdefault
See Also:   RGBImageFilter.filterRGBPixels



filterRGBPixels
public void filterRGBPixels(int x, int y, int w, int h, int pixels, int off, int scansize)(Code)
Filters a buffer of pixels in the default RGB ColorModel by passing them one by one through the filterRGB method.
See Also:   ColorModel.getRGBdefault
See Also:   RGBImageFilter.filterRGB



setColorModel
public void setColorModel(ColorModel model)(Code)
If the ColorModel is an IndexColorModel, and the subclass has set the canFilterIndexColorModel flag to true, we substitute a filtered version of the color model here and wherever that original ColorModel object appears in the setPixels methods. Otherwise overrides the default ColorModel used by the ImageProducer and specifies the default RGB ColorModel instead.
See Also:   ImageConsumer
See Also:   ColorModel.getRGBdefault



setPixels
public void setPixels(int x, int y, int w, int h, ColorModel model, byte pixels, int off, int scansize)(Code)
If the ColorModel object is the same one that has already been converted, then simply passes the pixels through with the converted ColorModel. Otherwise converts the buffer of byte pixels to the default RGB ColorModel and passes the converted buffer to the filterRGBPixels method to be converted one by one.
See Also:   ColorModel.getRGBdefault
See Also:   RGBImageFilter.filterRGBPixels



setPixels
public void setPixels(int x, int y, int w, int h, ColorModel model, int pixels, int off, int scansize)(Code)
If the ColorModel object is the same one that has already been converted, then simply passes the pixels through with the converted ColorModel, otherwise converts the buffer of integer pixels to the default RGB ColorModel and passes the converted buffer to the filterRGBPixels method to be converted one by one. Converts a buffer of integer pixels to the default RGB ColorModel and passes the converted buffer to the filterRGBPixels method.
See Also:   ColorModel.getRGBdefault
See Also:   RGBImageFilter.filterRGBPixels



substituteColorModel
public void substituteColorModel(ColorModel oldcm, ColorModel newcm)(Code)
Registers two ColorModel objects for substitution. If the oldcm is encountered during any of the setPixels methods, the newcm is substituted and the pixels passed through untouched (but with the new ColorModel object).
Parameters:
  oldcm - the ColorModel object to be replaced on the fly
Parameters:
  newcm - the ColorModel object to replace oldcm on the fly
