pillow处理图片横向与纵向的合并

一、代码

from PIL import Image

path_up = None # 记录合并后的图片地址
save_path1 = r".拼图上.png"
save_path2 = r".拼图下.png"
save_path3 = r".完整拼图.png"

def image_join(png1, png2, save_path, flag='lateral'):
    """
    :param png1: path
    :param png2: path
    :param flag: lateral or vertical
    :return:
    """
    img1, img2 = Image.open(png1), Image.open(png2)
    size1, size2 = img1.size, img2.size
    if flag == 'lateral': # 横向
        join_image = Image.new('RGB', (size1[0] + size2[0], size1[1])) # 创建一个2原图合并后大小的空白图
        loc1, loc2 = (0, 0), (size1[0], 0)
        join_image.paste(img1, loc1) # 将原图1黏贴到指定位置
        join_image.paste(img2, loc2) # 将原图2黏贴到指定位置
        join_image.save(save_path)
        return save_path
    elif flag == 'vertical': # 纵向
        join_image = Image.new('RGB', (size1[0], size1[1] + size2[1]))
        loc1, loc2 = (0, 0), (0, size1[1])
        join_image.paste(img1, loc1)
        join_image.paste(img2, loc2)
        join_image.save(save_path)
        return save_path

for i in range(1, 21):
    path = r".拼图.png"
    if i == 11:
        path_up = None
    if path_up:
        if i > 11:
            path_up = image_join(path_up, path, save_path2)
        else:
            path_up = image_join(path_up, path, save_path1)
    else:
        path_up = path

image_join(save_path1, save_path2, save_path3, flag='vertical')
