Python PIL For Loop可与多图像TIFF一起使用 [英] Python PIL For Loop to work with Multi-image TIFF

问题描述

每个tiff文件中都有4张图像.我不希望提取并保存它们(如果可能)，我只想使用一个for循环来查看它们中的每一个. (就像查看像素[0,0]一样)，并根据所有4种颜色的不同，我会做相应的事情.

Each tiff file has 4 images in it. I do not wish to extract and save them if possible, I would just like to use a for loop to look at each of them. (Like look at the pixel [0,0] )and depending on what color it is in all 4 I will do something accordingly.

使用PIL可以吗? 如果没有，我该怎么用.

Is this possible using PIL? If not what should I use.

推荐答案

您可以使用PIL图像的搜索"方法来访问tif的不同页面(或动画gif的帧).

You can use the "seek" method of a PIL image to have access to the different pages of a tif (or frames of an animated gif).

from PIL import Image

img = Image.open('multipage.tif')

for i in range(4):
    try:
        img.seek(i)
        print img.getpixel( (0, 0))
    except EOFError:
        # Not enough frames in img
        break
