I’m wanting to edit individual pixel values. Checking my code as I go, I tested to see if it would copy the top and bottom rows of pixels, and ignore everything else. But instead I got a copy of the entire picture. What am I not understanding about the python version of Processing?
Basic code structure:
fname = 'picture.png'
img = [0]*2 # used to initialize a 2 slot array
imgIndex = 0
def setup():
size(500, 500)
this.surface.setResizable(True)
img[0] = loadImage(fname)
this.surface.setSize(img[0].width, img[0].height)
img[1] = convolve(img[0])
def draw():
image(img[imgIndex], 0, 0)
def convolve(source, kernel):
target = createImage(source.width, source.height, RGB)
for y in range(source.height):
for x in range(source.width):
c = source.get(x, y)
if y in [0, source.height - 1]:
target.set(x, y, c)
return target
def keyReleased():
global imgIndex
if key == '0':
imgIndex = 0
elif key == '1':
imgIndex = 1
