Image Class

Overview

The Image class represents an image that can be drawn onto a graphical window. It supports resizing, scaling, alignment, rotation, and outlining.

Attributes

  • private Point position
    The position of the image in the graphical window.

  • private int width, height
    The dimensions of the image.

  • private BufferedImage image
    The buffered image to be rendered.

  • private GraphWin canvas
    The graphical window where the image is drawn.

  • private Color outlineColor
    The color of the image's outline (default: null).

  • private int outlineWidth
    The width of the outline (default: 1).

  • private String alignment
    The alignment of the image: "top-left", "top-right", "bottom-left", "bottom-right", or "center" (default: "center").

  • private double rotation
    The rotation angle of the image in degrees (default: 0).

  • private BufferedImage original
    A copy of the original image before any transformations.

  • private double scale
    The scale factor of the image.

Constructors

Image(Point position, String filePath)

Constructs an Image object from a file path with a specified position.

Parameters:

  • position - The position of the image as a Point object.
  • filePath - The file path to the image.

Image(Point position, URL filePath)

Constructs an Image object from a URL with a specified position.

Parameters:

  • position - The position of the image as a Point object.
  • filePath - The URL pointing to the image file.

Methods

void setOutline(Color color)

Sets the outline color of the image.

Parameters:

  • color - The outline color.

void setOutlineWidth(int width)

Sets the width of the image's outline.

Parameters:

  • width - The outline width.

void move(double dx, double dy)

Moves the image by the given offsets.

Parameters:

  • dx - The change in the x position.
  • dy - The change in the y position.

void setSize(int width, int height)

Sets the size of the image.

Parameters:

  • width - The new width of the image.
  • height - The new height of the image.

void setScale(double scaleFactor)

Scales the image by a given factor.

Parameters:

  • scaleFactor - The scale factor (e.g., 2.0 doubles the size, 0.5 halves it).

void setAlignment(String alignment)

Sets the alignment of the image.

Parameters:

  • alignment - The alignment of the image ("top-left", "top-right", "bottom-left", "bottom-right", "center").

void rotate(double angle)

Rotates the image by the given angle in degrees.

Parameters:

  • angle - The angle in degrees.

void draw(GraphWin canvas)

Draws the image onto a GraphWin canvas.

Parameters:

  • canvas - The GraphWin instance where the image will be drawn.

void undraw()

Removes the image from the graphical window.

void drawPanel(Graphics2D graphics)

Renders the image onto a Graphics2D panel, including alignment and outline.

Parameters:

  • graphics - The Graphics2D object used for rendering.
