  4. Individual Contributions • Gulam Vayda • Proposed Requirements 5, 10-12 • Project Manager (involved in all phases of project) • Class Structure/Documentation • Christian Boldan • Proposed Requirements 1-4 • Lead Coder/Tester • Chris Walker • Proposed Requirements 6-9 • Maintained Group Website and Presentation • Class Structure/Documentation

  5. 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.

  10. Implementation

  11. 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)

  12. Summary • Web Junkies’ Work Distribution • Requirements 1-12 and Design • 11 Requirements Implemented • 1 Requirement Yet To Be Done!
