python-3.x - Python将TIF格式的图像转换为PNG

Question

我正在运行下面的代码将文件从 tifs 转换为 PNG，但转换后的图像没有正确转换新文件被破坏，并且文件的一半中有行，如附件图像所示。知道为什么会发生这种情况吗？.

import os
from PIL import Image

yourpath = os.getcwd()
for root, dirs, files in os.walk(yourpath, topdown=False):
    for name in files:
        print(os.path.join(root, name))
        if os.path.splitext(os.path.join(root, name))[1].lower() == ".tif":
            if os.path.isfile(os.path.splitext(os.path.join(root, name))[0] + ".png"):
                print ("A png file already exists for %s" % name)
            # If a PNG is *NOT* present, create one from the tiff.
            else:
                outfile = os.path.splitext(os.path.join(root, name))[0] + ".png"
                try:
                    im = Image.open(os.path.join(root, name))
                    print("Generating jpeg for %s" % name)
                    im.thumbnail(im.size)
                    im.save(outfile, "png", quality=100)
                except Exception as e:
                    print (e)
