Question

我在目录中有一堆.tif图像，我试图使用PIL打开它们，并将它们保存为单个.tif文件，其中每个图像都是一个帧。根据此原则上应该可行：https://github.com/python-pillow/Pillow/issues/3636#issuecomment-508058396

到目前为止，我得到了：

from PIL import Image

img_frames = ['test_imgs/img1.tif',
            'test_imgs/img2.tif',
            'test_imgs/img3.tif']

# read the images and store them in a list
ordered_image_files = []
for img in img_frames:
    with Image.open(img) as temp_img:
        ordered_image_files.append(temp_img)

# save the first image and add the rest as frames
ordered_image_files[0].save('test.tif', 
                            save_all = True, 
                            append_images = ordered_image_files[1:])

运行此命令可以给我：

AttributeError: 'TiffImageFile' object has no attribute 'load_read'

如果我打印图像对象及其类，则会得到：

> print(ordered_image_files[0])
<PIL.TiffImagePlugin.TiffImageFile image mode=I;16B size=512x512 at 0x1028C6550>

> print(type(ordered_image_files[0]))
<class 'PIL.TiffImagePlugin.TiffImageFile'>

所以我认为阅读部分很好。

我是图像处理的新手，所以也许我缺少明显的东西。

谢谢。

完整的错误跟踪：

Traceback (most recent call last):
  File "/Users/mpages/miniconda3/envs/denoise_n2v/lib/python3.6/site-packages/PIL/ImageFile.py", line 161, in load
    read = self.load_read
AttributeError: 'TiffImageFile' object has no attribute 'load_read'

During handling of the above exception, another exception occurred:

我相信您的with语句正在关闭您的图像文件或将其放在可以访问该图像文件的内存上下文中，因此您可以尝试在我的Mac上正常运行：

for img in img_frames: 
    ordered_image_files.append(Image.open(img))

失败了，我在tifffile模块上取得了一些成功，如下所示：

import tifffile
img_frames = [ '1.tif', '2.tif', '3.tif' ]

with tifffile.TiffWriter('multipage.tif') as stack: 
    for filename in img_frames: 
        stack.save(tifffile.imread(filename))

关键字：Python，TIF，TIFF，tifffile，多页，多页，序列，图像，图像处理

用PIL / Image保存.tif堆栈
