                     java.awt.Color c1,
                     java.awt.Color c2)

Description copied from interface: Interface

Draw a line on the screen. The color of the line should ideally be smoothly interpolated. May only be called in a GUI rendering method.

Specified by:

drawLine in interface Interface

Parameters:

a - the start of the line

b - the end of the line

c1 - the color at the start of the line

c2 - the color at the end of the line

fillRect

public void fillRect(java.awt.Rectangle r,
                     java.awt.Color c1,
                     java.awt.Color c2,
                     java.awt.Color c3,
                     java.awt.Color c4)

Description copied from interface: Interface

Draw an axis-aligned rectangle on the screen. The color of the rectangle should ideally be smoothly interpolated. May only be called in a GUI rendering method.

Specified by:

fillRect in interface Interface

Parameters:

r - the rectangle to be rendered

c1 - the color at the top-left corner of the rectangle

c2 - the color at the top-right corner of the rectangle

c3 - the color at the bottom-right corner of the rectangle

c4 - the color at the bottom-left corner of the rectangle

drawRect

public void drawRect(java.awt.Rectangle r,
                     java.awt.Color c1,
                     java.awt.Color c2,
                     java.awt.Color c3,

Description copied from interface: Interface

Draw the outline of an axis-aligned rectangle on the screen. The color of the rectangle should ideally be smoothly interpolated. May only be called in a GUI rendering method.

Specified by:

drawRect in interface Interface

Parameters:

r - the rectangle to be rendered

c1 - the color at the top-left corner of the rectangle

loadImage

public int loadImage(java.lang.String name)

Description copied from interface: Interface

Load an image into memory and return a number that may be used to draw that image. Should only be called during initialization. The name string should ideally be the filename of the image, not including the path, since the implementation of this interface must ideally provide the directory in which the images are located.

Specified by:

loadImage in interface Interface

Parameters:

name - a string indicating the location of the image to be loaded

Returns:

a number identifying the image

Draw an image.

Specified by:

drawImage in interface Interface

Parameters:

r - the rectangle specifying the position of the image

rotation - the rotation of the image in units of 90 degrees counter-clockwise
