imageprocessing
Interface IImage

public interface IImage

In addition to the methods listed here, concrete classes are encouraged to have a constructor which takes one String parameter, the name of a file to be opened as an image. In addition, the toString() method should return a string representation of the image which can be copied and pased into a text editor to be saved as a ppm/pgm (this means the string must conform to the standard file format for those files).

Method Summary

int	getHeight()
int[]	getPixel(int r, int c)
int	getWidth()
void	setPixel(int r, int c, int[] values)

Method Detail

getWidth

public int getWidth()

Returns:

The width (number of columns) of the image

getHeight

public int getHeight()

Returns:

The height (number of rows) of the image

setPixel

public void setPixel(int r,
                     int c,
                     int[] values)
              throws IndexOutOfBoundsException,
                     IllegalArgumentException

Parameters:

r - The row of the pixel being set

c - The column of the pixel being set

values - an array of values to be set at location (r,c) For color images, for example, this would be a size three array ([R G B] ordering).

Throws:

IndexOutOfBoundsException - thrown if the given row or column is out of bounds

IllegalArgumentException - thrown if the length of the values parameter is inappropriate for the image.

getPixel

public int[] getPixel(int r,
                      int c)
               throws IndexOutOfBoundsException

Parameters:

r - The row of the pixel being set

c - The column of the pixel being set

Returns:

an array of values at the given row and column. For color images, for example, this would be a size three array ([R G B] ordering).

Throws:

IndexOutOfBoundsException - thrown if the given row or column is out of bounds
