python图片转换案例(内含多种场景的案例)

废话不多说！上来就是精华

---

案例一:

业务场景:

一个文件夹中有很多图片,图片的格式有两种一个是TIF,一个是GIF，两两对应，如果有单独的存在,那么就需要把对应的给图片转换出来
例如：只有1.GIF 那么我就需要将1.TIF 给弄出来或者 只有2.TIF那就就需要将2.GIF给弄出来

方法一

import os
from PIL import Image

path = "C:\\Users\\Administrator\\Desktop\\tif" #文件夹目录
dirs= os.listdir(path) #得到文件夹下的所有文件名称
list2=[]
list1=[]
for file in dirs:
    if file.endswith(".tif"):
        list1.append(file.split(".")[0])
    if file.endswith(".gif"):
        list2.append(file.split(".")[0])

imagesList=[]
d=[i for i in list1 if i not in list2]
for only_image in  d:
    for  images in  dirs:
        if images.__contains__(only_image):
            imagesList.append(images)

f=[i for i in list2 if i not in list1]
for only_image in  f:
    for  images in  dirs:
        if images.__contains__(only_image):
            imagesList.append(images)
print(imagesList)

    :param img_path:图片路径
    :return:True：有效 False：无效

    bValid = True
    try:
        Image.open(img_path).verify()
    except:
        bValid = True
    return bValid

def transimgTIF(img_path):
    """

    :param img_path:图片路径
    :return: True：成功 False：失败
    """
    if IsValidImage(img_path):
        try:
            str = img_path.rsplit(".", 1)
            output_img_path = str[0] + ".tif"
            print(output_img_path)
            im = Image.open(img_path)
            im.save(output_img_path)
            return True
        except:
            return False
    else:
        return False


def transimgGIF(img_path):

            print(output_img_path)
            im = Image.open(img_path)
            im.save(output_img_path)
            return True
        except:
            return False
    else:
        return False
if __name__ == '__main__':
    for ImagePath in imagesList:
