Requirements 1-4

• The system shall have an icon that gives the user
  the ability to open the paint program by
  double-clicking on the icon.
• The system shall, when executed, open a window
  with a title bar. Inside the window, the
  dimension shall be fixed at 800 by 600 pixels.
• The system shall contain a white canvas inside
  the window with a dimension of 600 by 600 pixels.
• The system shall contain a panel of buttons on
  the left hand side of the window with a dimension
  of 200 by 600 pixels, which will represent all
  the drawing functions that the user can use as
  well as all the color options available for each
  function.

6
Requirements 5-8

• The system shall limit the user to the following
  color selection for each drawing function white,
  black, red, yellow, blue, green, orange, and
  purple.
• The system shall contain four drawing functions,
  the first of which is the Pen, allowing the
  user to draw a 2-pixel-wide, freeform line.
• The system shall have a second drawing function,
  the Brush, allowing the user to draw an
  8-pixel-wide, freeform line.
• The system shall have a third drawing function,
  the Paintroller, allowing the user to draw a
  16-pixel wide, freeform line.

7
Requirements 9-12

• The system shall have a fourth and final drawing
  function, the Paintcan, allowing the user to
  change an area of one color to another color.
• The system shall contain a menu bar directly
  below the title bar (which is not a part of the
  800 by 600 pixel window).
• The system shall have two options of the menu
  bar, the first of which is the Clear Canvas
  option, allowing the user to make the entire
  canvas white.
• The system shall have a second and final menu
  option, Close, allowing (perhaps redundantly)
  the user to close the window and program.

Requirement 9 The Paintcan

• Requirement Definition
• Drawing function that fills in an area of one
  color with another color
• Possible Implementation
• When clicked on the canvas, a method looks for
  all pixels of the same color surrounding the
  pixel clicked and changes it to the color
  selected (perhaps using some methods in Canvas
  class)
