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)

• 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.

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:

• 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)
