# JES Picture processing
# D. Thiebaut
# A demo of some of the functions available in JES for manipulating
# the pixels of an image.
# the image we are playing with
image = None
# changeColor( image ).
# Changes the amount of red, green and blue that is in an image
def changeColor( image ):
for x in range(0,getWidth(image)):
for y in range(0,getHeight(image)):
pixel = getPixel (image, x, y)
red = getRed(pixel)
green = getGreen(pixel)
blue = getBlue(pixel)
# the line below replaces the pixel with its original color. Change
# the amount of red, green and blue to see some change in the colors
newColor = makeColor( red, green, blue )
setColor( pixel, newColor )
return image
