So I'm pretty lost in Python. My teacher doesn't explain the commands for Python so I'm really confused on how to write this. I have to write a green screen type program that takes a picture with a green background and replaces it with another picture by looking at the color levels of each pixel and if the green color is a certain amount larger than blue/red then it will replace it with the other pictures pixel.
The pseudo code I have is:
#show the before pictures
#for each pixel in the foreground image:
# we first get the red, green and blue of this pixel
# if the red plus blue is greater than green (*)
# get the pixel from the background image at foreground pixel's location (**)
# set the background pixel's color to be the color obtained from the fg
#show the resulting picture (repaint)
#write the new picture to a file
You can use the writePictureTo(picture, path) function to save the image.
I know the basics to the program with the getRed()/blue/green and setRed(), but I don't know what to do about finding certain pixels in the foreground.
We are using JES version of python in class as well.
Any help would be greatly appreciated.
