Python拼接图片

拼接代码以下:

from PIL import Image


def mergei(files, output_file):
    """
    横向拼接
    :param files:须要拼接的文件,list 
    :param output_file: 拼接完成后的输出文件
    :return：生成拼接后的新的图片 
    """
    tot = len(files)
    img = Image.open(files[0])
    w, h = img.size[0], img.size[1]
    merge_img = Image.new('RGB', (w * tot, h), 0xffffff)
    i = 0
    for f in files:
        print(f)
        img = Image.open(f)
        merge_img.paste(img, (i, 0))
        i += w
    merge_img.save(output_file)


def mergej(files, output_file):
    """
    竖向拼接
    :param files:须要拼接的文件,list 
    :param output_file: 拼接完成后的输出文件
    :return：生成拼接后的新的图片 
    """
    tot = len(files)
    img = Image.open(files[0])
    w, h = img.size[0], img.size[1]
    merge_img = Image.new('RGB', (w, h * tot), 0xffffff)
    j = 0
    for f in files:
        print(f)
        img = Image.open(f)
        merge_img.paste(img, (0, j))
        j += h
    merge_img.save(output_file)


mergei(['xx_1.png', 'xx_2.png'], "abeam_merge.png")
mergej(['xx_1.png', 'xx_2.png'], "portait_merge.png")
