I am having a problem using PIL. I am trying to crop and image to a
square, starting from the center of the image, but when I try to crop
the image, it won't crop. Here are the relevant code snippets:
### Function I am testing ###
def create_square_image(file_name):
""" Creates a thumbnail sized image and turns it into a square """
image = Image.open(open(file_name))
size_tuple = image.size
width = size_tuple[0]
height = size_tuple[1]
square_length = 75
x1 = (width / 2) - (square_length / 2) x2 = x1 + square_length
y1 = (height / 2) - (square_length / 2) y2 = y1 + square_length
image.crop((x1,y1,x2,y2))
This doesn't change `image` but creates and returns a new cropped image
which you simply ignore.
image.save(file_name, "JPEG")
Ciao,

How do I output it to an actual file then? Or overwrite the existing
file?
Nevermind, I gotcha. I needed to do this:
def create_square_image(file_name):
""" Creates a thumbnail sized image and turns it into a square """
image = Image.open(open(file_name))
size_tuple = image.size
width = size_tuple[0]
height = size_tuple[1]
square_length = 75
x1 = (width / 2) - (square_length / 2)
x2 = x1 + square_length
y1 = (height / 2) - (square_length / 2)
y2 = y1 + square_length
new_image = image.crop((x1,y1,x2,y2))
try:
new_image.save(file_name, "JPEG")
except IOError:
print "Cannot create square image for", file_name
I needed to output the cropped image by getting the cropped image in
"new_image" and outputting the new file. I see what you were saying.
