python之如何使用 Python PIL 创建多帧 .tif 图像

我将如何使用 python PIL 创建一个新图像，其中包含多个帧。

new_Image = Image.new("I;16", (num_pixels,num_rows)) 
 
for frame in range((len(final_rows)/num_rows)): 
    pixels = new_Image.load() 
 
    for row in range(num_rows): 
        row_pixel = final_rows[row].getPixels() 
        for pixel in range(num_pixels): 
            pixels[pixel,row] = row_pixel[pixel] 
    print frame 
    new_Image.seek(frame) 

我尝试使用上面的代码，但它给了我一个 EOFError。该代码通过将我拥有的总行数除以每帧的行数来获得帧数。然后它将数据用作像素数据。我试图寻找一个新的框架，但我想它还没有被创建。如何创建这些框架？

编辑:我想要一个 .tif 文件格式

请您参考如下方法:

new_Image 是您已加载的内容，即 read - 如果它不超过一帧，您将无法移动到下一帧。

目前 PIL 不支持创建多帧 GIF，因此您需要切换到 pillow哪个 - 在 GitHub 上有一些示例代码.

更新

花时间进一步调查并发现了 images2gif 的错误修复版本，所以我所做的是使用 pip install images2gif 然后从 here 下载错误修复版本并覆盖由 pip 安装的版本，但您可以下载该错误修复版本并将其放在与您的开发文件相同的目录中。

然后我创建了一个 CreateGif.py 文件:

# coding: utf-8 
from __future__ import print_function # Python 2/3 compatibility 
import glob 
from PIL import Image 
from images2gif import writeGif 
 
DELAY=0.75  # How long between frames 
FRAMES = [] # Empty list of frames 
FIRST_SIZE = None # I am going to say that the first file is the right size 
OUT_NAME = "test.gif" # Name to save to 
filelist = glob.glob("*.jpg") # For this test I am just using the images in the current directory in the order they are 
 
for fn in filelist:  # For each name in the list 
    img = Image.open(fn) # Read the image 
    if FIRST_SIZE is None:  # Don't have a size 
        FIRST_SIZE = img.size  # So use this one 
    if img.size == FIRST_SIZE: # Check the current image size if it is OK we can use it 
        print ("Adding:", fn)  # Show some progress 
        FRAMES.append(img)   # Add it to our frames list 
    else: 
        print ("Discard:", fn, img.size, "<>", FIRST_SIZE) # You could resize and append here! 
 
print("Writing", len(FRAMES), "frames to", OUT_NAME) 
writeGif(OUT_NAME, FRAMES, duration=DELAY, dither=0) 
print("Done") 

在我的 测试目录中运行它导致:

F:\Uploads>python CreateGif.py 
Adding: Hidden.jpg 
Adding: NewJar.jpg 
Adding: P1000063.JPG 
Adding: P1000065.JPG 
Adding: P1000089.JPG 
Discard: WiFi_Virgin.jpg (370, 370) <> (800, 600) 
Writing 5 frames to test.gif 
Done 

并制作:

现在对于 TiFF 文件

首先我安装了 tiffile，pip install -U tiffile，我已经安装了 numpy，然后:

# coding: utf-8 
from __future__ import print_function # Python 2/3 compatibility 
import glob 
from PIL import Image 
import tifffile 
import numpy 
 
def PIL2array(img): 
    """ Convert a PIL/Pillow image to a numpy array """ 
    return numpy.array(img.getdata(), 
        numpy.uint8).reshape(img.size[1], img.size[0], 3) 
FRAMES = [] # Empty list of frames 
FIRST_SIZE = None # I am going to say that the first file is the right size 
OUT_NAME = "test.tiff" # Name to save to 
filelist = glob.glob("*.jpg") # For this test I am just using the images in the current directory in the order they are 
# Get the images into an array 
for fn in filelist:  # For each name in the list 
    img = Image.open(fn) # Read the image 
    if FIRST_SIZE is None:  # Don't have a size 
        FIRST_SIZE = img.size  # So use this one 
    if img.size == FIRST_SIZE: # Check the current image size if it is OK we can use it 
        print ("Adding:", fn)  # Show some progress 
        FRAMES.append(img)   # Add it to our frames list 
    else: 
        print ("Discard:", fn, img.size, "<>", FIRST_SIZE) # You could resize and append here! 
 
print("Writing", len(FRAMES), "frames to", OUT_NAME) 
with tifffile.TiffWriter(OUT_NAME) as tiff: 
    for img in FRAMES: 
        tiff.save(PIL2array(img),  compress=6) 
print("Done") 

生成了一个不错的 tiff 文件，但不幸的是，SO 查看器不显示 Windows 至少认为可以接受的多页 tiff 文件，如下所示。
