MediaScripting@SIGCSE2009

Approximate Agenda

This is an approximate agenda for the workshop. We expect to adapt the agenda based on participant interest.

I. Introduction [20 minutes]

• Goals of the workshop
• Meet and greet
  • Participants share goals
• Set up computers (install software or boot from flash drives)
• Introduction to media computing
• Introduction to MediaScripting (with demos)

II. MediaScripting in the GNU Image Manipulation Program (GIMP): The Basics [20 minutes]

• History of the GIMP
• Using the GIMP
• Scripting the GIMP in Python
• Scripting the GIMP in Scheme
• Scripting the GIMP with MediaScript
• Summary of basic library operations

III. Hands on Activity: Creating Images [40 minutes]

• Tasks
  • Write program to create images (house, face)
  • Parameterize
  • Add randomness

IV. Discuss/Debrief first activity [10 minutes]

• Share images
• Discuss ways to use in class

V. Break [15 minutes]

The break is scheduled for 8:30-9:00. We will try to resume at about 8:45.

VI. Hands on Activity: Simulating Spirographs [20 minutes]

• The task: Rotate a stamp around an inner circle
• Explore sample code
• Activity: Generate and share images

VII. Example/Discussion: Design Choices [15 minutes]

• The task: How do we build a library to support drawing regular polygons?
• Question: Focus on operations (e.g., image-draw-regular-polygon!) or on data (e.g., poly-new)?
• Question: If we focus on data, should the representation be pure or impure?
• Sample code

VIII. Hands on Activity/Discussion: Illustrating Runtime [15 minutes]

• Explore two procedures: step! and smallest
• Consider other applications

IX. Additional Demonstrations [15 minutes]

• Higher-order approaches: Using map-like procedures to construct and filter images
• Building new drawing tools
• Using the core GIMP PDB operations
• Inkscape
• Student projects

X. Discussion/Wrapup [10 minutes]

• Ideas, directions, questions
• Where to go for more info
• Evaluations! (in the Hot Links! section in the upper-right corner of the SIGCSE Symposium home page at http://www.cs.arizona.edu/groups/sigcse09/).
