Constructor Detail

Crop

Crop(WorldImage base,
     int left,
     int right,
     int top,
     int bottom)

Constructor for objects of class Crop

Parameters:

base - the image to crop

left, - right, top, bottom the borders to crop to

Method Detail

draw

public void draw(Graphics2D g)

Description copied from interface: WorldImage

Draw this image in the provided Graphics2D context.

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 AImage

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

getLeft

public int getLeft()

Description copied from class: AImage

Getter for the left edge of the bounding box.

Specified by:

getLeft in interface WorldImage

Overrides:

getLeft in class AImage

Returns:

the minimum x coordinate of the image

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

getTop

public int getTop()

Description copied from class: AImage

Getter for the top of the bounding box.

Specified by:

getTop in interface WorldImage

Overrides:

getTop in class AImage

Returns:

the minimum y coordinate of the image

make

static WorldImage make(WorldImage base,
                       int left,
                       int right,
                       int top,
                       int bottom)

Pseudo-constructor for objects of class Crop

Parameters:

base - the image to crop

left, - right, top, bottom the borders to crop to

toIndentedString

public String toIndentedString(String indent)

Description copied from interface: WorldImage

Produce a String that represents this image, indented by the given indent.

Define this in all concrete subclasses.

Convention: The result of toIndentedString() will neither begin nor end with a newline; the specified indent will immediately follow each internal newline.

Parameters:

indent - the given prefix representing the desired indentation

Returns:

the String representation of this image
