csc 104#4

so for the class on Tuesday we talked about "switching pixel" of the pictures
as we know pictures are basically make up by green, blue and red pixels..
within a picture, there could be over thousands and thousands of pixels..
with Dr.Racket we can playing around with those pixels..
let say there are 500 green, 500 blue and 500 red pixels within a picture..
we can replace the green pixels with red pixels and that would gives you a different look of the picture..it was not difficult but commands were a little bit complicated , i have to watch the video and practice more make sure i ace in this topic! this is also an interesting topic and  practical that allows us to play around with photo :)


at the end of the class we got our tests back but it was not the mark i expect to get...:(
