2007S, CSC151 Class 25: Recursion with Helper Procedures
* I will continue to reserve time at the start of class for any campus
issues you want to discuss.
* Remember that the vast majority of those on campus are good,
supportive people
* Work to focus on the positive aspects of Mary B. James
Admin:
* Are there questions on Assignment 6?
* Typos fixed
* (image-colorscale image dark light)
* Write (rgb-recolor color dark light)
* (image-variant image rgb-recolor) NOT CORRECT
* The second parameter to image-variant is a procedure
of ONE PARAMETER, rgb-recolor is a procedure of THREE PARAMETERS
ONE != THREE (except mod 2)
Instead * of rgb-recolor, use a one-parameter variant
* Anonymous (lambda (color) (rgb-recolor color ...))
* Named with a let
* What would an anonymous blue-yellow procedure look like?
(image-variant image (lambda (color) (rgb-recolor color blue yellow)))
* It looks like we're on target to distribute the next exam tomorrow.
* Reading for Wednesday: List Recursion, Revisited.
