def changeRGB(picture, Red, REMOVED, Blue):
for p in getPixels(picture):
setRed(p, getRed(p)(1+Red))
setREMOVED(p, getREMOVED(p)(1+REMOVED))
setBlue(p, getBlue(p)(1+Blue))
What does setRed(p,getRed(p)(1+Red))mean?
| This means that you want to set the red value to the previous value times the percent change + 1. When you type an asteric on the Coweb, it doesn't show up. REMOVED the FAQ on how to fix this. Student1594 |
def changeRGB(pic, ra, ga, ba):
for px in getPixels(pic):
red=getRed(px)
green=getREMOVED(px)
blue=getBlue(px)
setRed(px, red ra)
setREMOVED(px, green ga)
setBlue(px, blue ba)
show(pic)
def changeRGB(pict, r, g, b):
for p in getPixels(pict):
re=getRed(p)
gr=getREMOVED(p)
bl=getBlue(p)
setRed(p, re(1+r))
setREMOVED(p, gr(1+g))
setBlue(p, bl(1+b))
Are there any TAs out there and is this okay? thanks, Sarah C.
def changeRGB(picture, r, g, b):
for p in getPixels(picture):
if r > -1 and r < 1:
setRed(p, getRed(p) * (r + 1))
if g > -1 and g < 1:
setREMOVED(p, getREMOVED(p) * (g + 1))
if b > -1 and b < 1:
setBlue(p, getBlue(p) * (b + 1))
