You should often see a picture of the ninth palace grid posted by someone on your moments. The essence is to cut a picture into nine pieces, and then post the nine pictures together on Wechat.

When it comes to image cutting, Python can be implemented. The main Python library used is Pillow, and pip install pillow can be used for installation. The main steps for image cutting are as follows:

Open the picture to be processed

Judge whether the open picture is square or not

If it is a square, divide it into nine equal parts. If it is not a square, fill it with white first, and then divide it into nine equal parts.

Save the processed picture

The main implementation code is as follows:

# populate the new image

Def fill_image (image):

Width, height = image.size

_ length = width

If height > width:

_ length = height

New_image = Image.new (image.mode, (_ length, _ length), color='white')

If width > height:

New_image.paste (image, (0, int ((_ length-height) / 2)

Else:

New_image.paste (image, (int ((_ length-width) / 2), 0))

Return new_image

# crop image

Def cut_image (image):

Width, height = image.size

_ width = int (width / 3)

Box_list = []

For i in range (0,3):

For j in range (0,3):

Box = (j * _ width, I * _ width, (j + 1) * _ width, (I + 1) * _ width)

Box_list.append (box)

Image_list = [image.crop (box) for box in box_list]

Return image_list

# Save the pictures in the image list

Def save_images (image_list, res_dir):

Index = 1

If not os.path.exists (res_dir):

Os.mkdir (res_dir)

For image in image_list:

New_name = os.path.join (res_dir, str (index) + '.png')

Image.save (new_name, 'PNG')

Index + = 1
