我没有使用python的经验，但是这个脚本的所有者没有响应。
当我将照片拖到此脚本上以创建蒙太奇时，它最终会切掉右侧边缘的最后一张照片的一半。
4张照片，
1 2 3 4 5 6 7 8图片4和8通常会减半。 照片的空间（尽管它是空白的）
我想知道是什么原因造成的。
我认为它可能是裁剪，但它几乎像图片的一半没有导入或检测到。
好吧，你将选定的照片拖到脚本上，输出这样的东西
因此，您可以拍摄大量照片或屏幕截图，并将它们合并为一个文件，而不是单独添加每张照片。
每张照片的大小最大约为500x250。
编辑：这是预览的上传，因为你可以看到图像有插槽，但如果有意义，它们会“消失”。
EDIT2：这个脚本曾经有效，我还没有编辑过它。 它已经制作了约70个截图蒙太奇。 没有错误或任何事情。 我的计算机可以做些什么来破坏图像的导入吗？

When I drag my photos over this script, to create a montage, it ends up cutting off half of the last photo on the right side edge.
Being 4 pictures wide,
1 2 3 4 5 6 7 8Pictures 4 and 8 usually get halved. The space is there for the pictures (its blank though)
I was wondering what would be causing this.
I have thought it is possible that it was cropping, but its almost like the half of the picture isn't imported or detected.
Well, you drag selected photos over the script , it outputs something like this
So you can take a bunch of photos or screenshots, and combine them into one single file, easily instead of adding each photo individually.
Size of each photo is roughly 500x250 at max.
EDIT: Here is the upload of the preview, as you can see the images have the slots, but they are "disappearing" if that makes sense.
EDIT2: This script has worked at one time, I haven't edited it or anything. It had worked on a ~70 screenshot montage. No errors or anything. Is there something that my computer could be doing to disrupt the importing of the images?

在大小计算中，您使用image.size[1]作为宽度，但这就是高度！ 使用image.size[0]作为宽度，使用image.size[1]作为高度。
还有一些小风格的笔记：
你真的需要脚本始终从程序的目录运行吗？ 在任何情况下， os.chdir(os.path.dirname(sys.argv[0]))阻止程序以./montage.py形式执行，因此您可能希望使用abspath来允许从当前调用目录。您可以将for循环更改为，而不必更新计数器i
for i,image in enumerate(images):以下行无效，因为变量被覆盖/从未使用过：
width = 0 height = 0 i = 0 sum_x = max_y = 0总而言之，代码可能如下所示：
#!/usr/bin/env python import os.path import sys from time import strftime import Image row_size = 4 margin = 3 def generate_montage(filenames, output_fn): images = [Image.open(filename) for filename in filenames] width = max(image.size[0] + margin for image in images)*row_size height = sum(image.size[1] + margin for image in images) montage = Image.new(mode='RGBA', size=(width, height), color=(0,0,0,0)) max_x = 0 max_y = 0 offset_x = 0 offset_y = 0 for i,image in enumerate(images): montage.paste(image, (offset_x, offset_y)) max_x = max(max_x, offset_x + image.size[0]) max_y = max(max_y, offset_y + image.size[1]) if i % row_size == row_size-1: offset_y = max_y + margin offset_x = 0 else: offset_x += margin + image.size[0] montage = montage.crop((0, 0, max_x, max_y)) montage.save(output_fn) if __name__ == '__main__': basename = strftime("Montage %Y-%m-%d at %H.%M.%S.png") exedir = os.path.dirname(os.path.abspath(sys.argv[0])) filename = os.path.join(exedir, basename) generate_montage(sys.argv[1:], filename)In the size calculation, you use image.size[1] for the width, but that's the height! Use image.size[0] for the width and image.size[1] for the height instead.
Also, a couple of minor stylistic notes:
Do you really need the script to always run from the program's directory? In any case, os.chdir(os.path.dirname(sys.argv[0])) prevents the program from being executed as ./montage.py, so you may want to use a abspath to allow the invocation from the current directory.Instead of having to update the counter i, you can change the for loop to
for i,image in enumerate(images):The following lines have no effect, since the variables are overwritten / never used:
width = 0 height = 0 i = 0 sum_x = max_y = 0All in all, the code could look like this:
#!/usr/bin/env python import os.path import sys from time import strftime import Image row_size = 4 margin = 3 def generate_montage(filenames, output_fn): images = [Image.open(filename) for filename in filenames] width = max(image.size[0] + margin for image in images)*row_size height = sum(image.size[1] + margin for image in images) montage = Image.new(mode='RGBA', size=(width, height), color=(0,0,0,0)) max_x = 0 max_y = 0 offset_x = 0 offset_y = 0 for i,image in enumerate(images): montage.paste(image, (offset_x, offset_y)) max_x = max(max_x, offset_x + image.size[0]) max_y = max(max_y, offset_y + image.size[1]) if i % row_size == row_size-1: offset_y = max_y + margin offset_x = 0 else: offset_x += margin + image.size[0] montage = montage.crop((0, 0, max_x, max_y)) montage.save(output_fn) if __name__ == '__main__': basename = strftime("Montage %Y-%m-%d at %H.%M.%S.png") exedir = os.path.dirname(os.path.abspath(sys.argv[0])) filename = os.path.join(exedir, basename) generate_montage(sys.argv[1:], filename)更多推荐
