如何完成这个python函数保存在同一个文件夹中?

我正在尝试编写我的第一个真正的python函数,它可以实现一些实际的功能。我想要完成的是搜索一个给定的文件夹,然后打开所有的图像,并将它们合并在一起,这样它们就形成了一个电影胶片图像。想象一下在一张图片中有5张图片叠在一起。在

我现在有了这段代码,应该很好,但可能需要修改:

import os
import Image

def filmstripOfImages():

    imgpath = '/path/here/'
    files = glob.glob(imgpath + '*.jpg')

    imgwidth = files[0].size[0]
    imgheight = files[0].size[1]
    totalheight = imgheight * len(files)

    filename = 'filmstrip.jpg'
    filmstrip_url = imgpath + filename

    # Create the new image. The background doesn't have to be white
    white = (255,255,255)
    filmtripimage = Image.new('RGB',(imgwidth, totalheight),white)  
    row = 0
    for file in files:
        img = Image.open(file)

        left = 0
        right = left + imgwidth
        upper = row*imgheight
        lower = upper + imgheight
        box = (left,upper,right,lower)
        row += 1

        filmstripimage.paste(img, box)
    try:
        filmstripimage.save(filename, 'jpg', quality=90, optimize=1)
    except:
        filmstripimage.save(miniature_filename, 'jpg', quality=90)")

我如何修改它以保存新的电影胶片.jpg在我加载图片的同一个目录中?它可能有一些东西丢失或错误,有人知道吗?在

如果您不是在开玩笑,您的脚本有几个问题,例如glob.glob()返回文件名列表(字符串对象,而不是图像对象),因此files[0].size[0]将无法工作。在

这不是对您问题的回答,但可能会有所帮助:

#!/usr/bin/env python
import Image

def makefilmstrip(images, mode='RGB', color='white'):
    """Return a combined (filmstripped, each on top of the other) image of the images.

    """
    width  = max(img.size[0] for img in images)
    height = sum(img.size[1] for img in images)

    image = Image.new(mode, (width, height), color) 

    left, upper = 0, 0
    for img in images:
        image.paste(img, (left, upper))
        upper += img.size[1]

    return image

if __name__=='__main__':
    # Here's how it could be used:
    from glob import glob
    from optparse import OptionParser

    # process command-line args
    parser = OptionParser()
    parser.add_option("-o", "--output", dest="file",
                      help="write combined image to OUTPUT")

    options, filepatterns = parser.parse_args()
    outfilename = options.file

    filenames = []
    for files in map(glob, filepatterns):
        if files:
            filenames += files

    # construct image
    images = map(Image.open, filenames)    
    img = makefilmstrip(images)
    img.save(outfilename) 

示例:

^{pr2}$

我想如果你把你的try部分改成这样:

filmstripimage.save(filmstrip_url, 'jpg', quality=90, optimize=1)
