Method Summary

protected char[][]	filter(char[][] channels, int width, int height, double[][] coeffs, double weight) this method does a discrete convolution. it convolutes the channel data with the given coeff matrix and the given weight. for that it uses the so called 'output side' algo which allways calculates one whole output pixel. the algo is implemented in two loops using a index array.
javax.swing.JComponent	getEditor(IPicture preview)
FilterData	getFilter(int index) returns the indexed filter
int	getFilterCount() returns the number of stored filter coeffs
java.lang.String	getName() returns the processors name
FilterData	getSelectedFilter() returns the selected filter
char[][]	process(char[][] channels, int width, int height) processes the given channels and returns the modified version. can also directly work with the given data and can return this.
void	setSelectedFilter(FilterData d) sets the selected filter

                        int width,
                        int height)

processes the given channels and returns the modified version. can also directly work with the given data and can return this.

Specified by:

process in interface IPictureProcessor

Parameters:

channels - - the channels to be processed

Returns:

the processed channels

getEditor

public javax.swing.JComponent getEditor(IPicture preview)

Specified by:

getEditor in interface IPictureProcessor

getName

public java.lang.String getName()

returns the processors name

Specified by:

getName in interface IPictureProcessor

filter

protected char[][] filter(char[][] channels,
                          int width,
                          int height,
                          double[][] coeffs,
                          double weight)

this method does a discrete convolution. it convolutes the channel data with the given coeff matrix and the given weight. for that it uses the so called 'output side' algo which allways calculates one whole output pixel. the algo is implemented in two loops using a index array.

Parameters:

channels -

width -

height -

coeffs -

weight -

Returns:
