Constructor Detail

Scale2xImageFilter

public Scale2xImageFilter(int w,
                          int h)

Constructor for Scale2xImageFilter.

Method Detail

setDimensions

public void setDimensions(int w,
                          int h)

Override the dimensions of the source image and pass the dimensions of the new scaled size to the ImageConsumer.

Note: This method is intended to be called by the ImageProducer of the Image whose pixels are being filtered. Developers using this class to filter pixels from an image should avoid calling this method directly since that operation could interfere with the filtering operation.

setProperties

setPixels

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

Apply Scale2x here. FIXME: This method (setPixels() with a byte array) has not been tested, mainly because I don't readily have an ImageProducer which serves up bytes for the pixels. Also, this method just copies the bytes to integers and calls the other method, which isn't very efficient. Once the int method is optimized, this method will be re-written.

Note: This method is intended to be called by the ImageProducer of the Image whose pixels are being filtered. Developers using this class to filter pixels from an image should avoid calling this method directly since that operation could interfere with the filtering operation.

setPixels

                      int w,
                      int h,
                      java.awt.image.ColorModel model,
                      int[] pixels,
                      int off,
                      int scansize)

This method is where the Scale2x algorithm is applied.
