Constructor Detail

RectangularImage

RectangularImage(int width,
                 int height,
                 Color color,
                 Mode mode)

height -

color -

RectangularImage

RectangularImage(int width,
                 int height,
                 IColor color,
                 Mode mode)

Method Detail

equals

public boolean equals(Object other)

Description copied from interface: WorldImage

Is this the same as another WorldImage, as expression trees? Define this at every level that has instance variables.

Specified by:

equals in interface WorldImage

Overrides:

equals in class ColoredImage

Parameters:

other - the object to compare with this

Returns:

true iff the images are isomorphic expression trees, with equal fields.

getBottom

public int getBottom()

Description copied from interface: WorldImage

Produce the bottom of the bounding box.

Returns:

the y coordinate of the bottom of the bounding box

getRight

public int getRight()

Description copied from interface: WorldImage

Produce the bottom of the bounding box.

Returns:

the x coordinate of the right edge of the bounding box

hashCode

public int hashCode()

Description copied from interface: WorldImage

Get a hash code for the WorldImage. Needs to agree with equals(). In our case, "equals" means they're the same as expression trees.

Specified by:

hashCode in interface WorldImage

Overrides:

hashCode in class ColoredImage

replaceDimensions

abstract RectangularImage replaceDimensions(int width,
                                            int height)

Functional setter for width and height.

Parameters:

width -

height -

Returns:

a new image just like this one but with different dimensions.

replaceHeight

RectangularImage replaceHeight(int height)

Functional setter for height.

Parameters:

height -

Returns:

a new image just like this one but with different height.

replaceWidth

RectangularImage replaceWidth(int width)

Functional setter for width.

Parameters:

width -

Returns:

a new image just like this one but with different width.
