Basic Image Manipulation

Working with color information

In the following image, I set the red and green channels to 0 to make the image blue.

Alpha blending

My blending function takes in a background and a foreground image. The foreground image has to be taken in blue screen. The blend function then creates a mask from the bluescreen image and blend the two image together.


I write a function that can scale an image down to a specified ratio. I do the scaling by down-sampling the image.


I wrote functions to visualize Julia and Mandelbrot sets. By changing the view window and the color rules, I get many interesting images.

Scanline fill demonstration

I created an image to demonstrate the scanline fill algorithm. It is not particularly good since I let the scanline run a bit fast. But it gives a decent visual perspective of how scanline fill works.
