Overview
Administrivia
(irgb-new red green blue)
- create a new color(image-set-pixel! image col row color)
- set the color of a pixel(image-get-pixel image col row)
- get the color of a pixela(irgb-red color)
- get the red component(irgb-green color)
- get the green component(irgb-blue color)
- get the blue component(color->rgb-list color)
- get a list of the three components(color->irgb color)
- convert some representations to the
RGB representation.(define color-transform (lambda (color) (irgb-new ___ ; computation of red component ___ ; computation of green component ___ ; computation of blue component )))
(define only-blue (lambda (color) (irgb-new ___ ___ ___)))
