Overview:
• Color grids.
• Example.
• Anonymous Procedures.
• Lab.

Color Grids

• Another way to explore design spaces.
• I don't know the tradition.
• A bit more difficult in Scheme.
• Our technique: Use a menu item, specify red, green, and blue components using functions.

An Example

• Because the color grid stuff may be a bit confusing, I'll do my best to demonstrate it.
• Some key issues:
  • Any procedures you use must be linked from the GIMP scripts folder.
  • If you change your files, you need to reload those files, but not using the console.
  • You can do this without the console at all!
  • You can do this without writing code in files (using the trick known as anonymous procedures).
  • You can do this using the console (if you don't like menus).

Anonymous Procedures

• Just like procedures, except without the define or the let.
• Can be applied.
• Can be used in things like color-grid.

Lab

• Do the lab.
• Be prepared to reflect.
Back to Randomized Images. On to Discussion of Exam 2.
