< H2 > Test Code 1 < / H2 >
from PIL import Image
img = Image.open("qqqqq.png")
print (img.size) -sharp(10,24)
print(img.getpixel((10,24))) -sharp:
-sharp IndexError: image index out of range
the picture is 10 to 24 in size, so why is it out of range? Do you want to subtract the coordinates by 1? The point in the lower right corner should be (9 ~ 23)?
< H2 > Test Code 2 < / H2 >
from PIL import Image
img = Image.open("qqqqq.png")
print(img.getpixel((4,4))) -sharp:3
what does this 3 mean? Shouldn"t it be a result similar to (255255255)?
< H2 > Test Code 3 < / H2 >
img = Image.open("qqqqq.png")
img.putpixel((4,4),(255,255,0)) -sharp:
-sharpTypeError: function takes exactly 1 argument (3 given)
img.save("qqqqq-2.png","png")
change the color of a pixel and look at the wrong number of parameters given by the error prompt.
