Constructor Detail

EditableImage

public EditableImage(int width,
                     int height)

The constructor. Constructs a new image with given dimensions.

Parameters:

width - the width of this image.

height - the height of this image.

Method Detail

get

public int get(int x,
               int y)

Gets the pixel at x, y.

Parameters:

x - x-coordinate

y - y-coordinate

Returns:

the pixel value

set

public void set(int x,
                int y,
                int value)

Sets the pixel at x, y to value

Parameters:

x - x-coordinate

y - y-coordinate

value - the pixel value

set

public void set(int x,
                int y,
                int w,
                int h,
                int[] values)

Copies a rectangular area of pixels from the array to this image. The target area's top left corner is at x, y and the width is w and the height is h. The values in the source array should be in order: left to right and top to bottom.

Parameters:

x - the x-coordinate of the top left corner of the target area

y - the y-coordinate of the top left corner of the target area

w - the width of the target area

h - the height of the target area

values - the array of values

set

public void set(EditableImage source,
                java.awt.Rectangle rect,
                int x,
                int y)

Copies pixels from another image. The pixels shown by the given rectangle from the source image are copied to this image to location x, y.

Parameters:

source - the source image

rect - the area of the source image to be copied

x - the target x-coordinate

y - the target y-coordinate

getWidth

public int getWidth()

Gets the width of this image.

Returns:

the width in pixels.

getHeight

public int getHeight()

Gets the height of this image.

Returns:

the height in pixels.

copyFromImage

public void copyFromImage(EditableImage source,
                          int x,
                          int y)

Copies the whole source image to this image to position x, y. Portions of the source image not within this image's boundaries are not copied to anywhere.

Parameters:

source - the source image

x - start position x-coordinate

y - start position y-coordinate

getPart

public EditableImage getPart(java.awt.Rectangle rect)

Returns a sub-image of this image as a new EditableImage.

Parameters:

rect - the rectangel representing the sub-image's area

Returns:

a new EditableImage

getBufferedImage

public java.awt.image.BufferedImage getBufferedImage()
