Method Summary

void	draw(Graphics2D g) Draw this image in the provided Graphics2D context.

int	getBottom() Produce the bottom of the bounding box.
int	getRight() Produce the bottom of the bounding box.
(package private) static RasterImage	make(WorldImage base) Pseudo-constructor for a frozen (memoized) image.
protected void	renderIfNecessary() make sure rendering isn't null

Method Detail

draw

public void draw(Graphics2D g)

Description copied from interface: WorldImage

Draw this image in the provided Graphics2D context.

Specified by:

draw in interface WorldImage

Overrides:

draw in class RasterImage

Parameters:

g - the provided Graphics2D context

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 RasterImage

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.

Specified by:

getBottom in interface WorldImage

Overrides:

getBottom in class RasterImage

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.

Specified by:

getRight in interface WorldImage

Overrides:

getRight in class RasterImage

Returns:

the x coordinate of the right edge of the bounding box

make

static RasterImage make(WorldImage base)

Pseudo-constructor for a frozen (memoized) image.

Parameters:

base - the existing image to freeze

renderIfNecessary

protected void renderIfNecessary()

Description copied from class: RasterImage

make sure rendering isn't null

Overrides:

renderIfNecessary in class RasterImage
