Python 尝试从一组图像创建GIF

我正在尝试使用python从一组PIL图像创建一个动画

.gif

以下是我到目前为止的情况：

from images2gif import writeGif
from PIL import Image, ImageDraw
import os
import sys
import random
import argparse
import webbrowser

filename = ""

def makeimages():
    for z in range(1, 31):
        dims = (400, 400)  # size of image
        img = Image.new('RGB', dims)  # crete new image
        draw = ImageDraw.Draw(img)
        r = int(min(*dims)/100)
        print "Image img%d.png has been created" % z

        n = 1000

        for i in range(n):
            x, y = random.randint(0, dims[0]-r), random.randint(0, dims[1]-r)
            fill = (random.randint(0, 255), random.randint(0, 255), random.randint(0, 255))
            draw.ellipse((x-r, y-r, x+r, y+r), fill)

       img.save('.img%d.png' % z)

def makeAnimatedGif():
    # Recursively list image files and store them in a variable
    path = "./Images/"
    os.chdir(path)
    imgFiles = sorted((fn for fn in os.listdir('.') if fn.endswith('.png')))

    # Grab the images and open them all for editing
    images = [Image.open(fn) for fn in imgFiles]

    global filename
    filename = filename + ".gif"
    writeGif(filename, images, duration=0.2)
    print os.path.realpath(filename)
    print "%s has been created, I will now attempt to open your" % filename
    print "default web browser to show the finished animated gif."
    #webbrowser.open('file://' + os.path.realpath(filename))


def start():
    print "This program will create an animated gif image from the 30 images provided."
    print "Please enter the name for the animated gif that will be created."
    global filename
    filename = raw_input("Do Not Use File Extension >> ")
    print "Please wait while I create the images......"
    makeimages()
    print "Creating animated gif...."
    makeAnimatedGif()

start()

以下是错误：

Traceback (most recent call last):
  File "Final.py", line 60, in <module>
    start()
  File "Final.py", line 56, in start
    makeimages()

所需的输出是让python创建30个图像，然后将它们组合在一起并保存为GIF文件。

代码中有一个输入错误<代码>img.save（'.img%d.png'%z）应该是预期的

代码中的主要缺陷是生成的图像不在生成gif的

/images/

中

您应该使

/Images/

在目录中不存在

下面的代码是一个修复程序，它可以正常工作

from images2gif import writeGif
from PIL import Image, ImageDraw
import os
import sys
import random
import argparse
import webbrowser

filename = ""


def makeimages():
    # Create the dir for generated images
    if not os.path.exists("Images"):
        os.makedirs("Images")
    for z in range(1, 31):
        dims = (400, 400)  # size of image
        img = Image.new('RGB', dims)  # crete new image
        draw = ImageDraw.Draw(img)
        r = int(min(*dims)/100)
        print "Image img%d.png has been created" % z

        n = 1000

        for i in range(n):
            x, y = random.randint(0, dims[0]-r), random.randint(0, dims[1]-r)
            fill = (random.randint(0, 255), random.randint(0, 255), random.randint(0, 255))
            draw.ellipse((x-r, y-r, x+r, y+r), fill)

        img.save('Images/.img%d.png' % z)

def makeAnimatedGif():
    # Recursively list image files and store them in a variable
    path = "./Images/"
    os.chdir(path)
    imgFiles = sorted((fn for fn in os.listdir('.') if fn.endswith('.png')))

    # Grab the images and open them all for editing
    images = [Image.open(fn) for fn in imgFiles]

    global filename
    filename = filename + ".gif"
    writeGif(filename, images, duration=0.2)
    print os.path.realpath(filename)
    print "%s has been created, I will now attempt to open your" % filename
    print "default web browser to show the finished animated gif."
    #webbrowser.open('file://' + os.path.realpath(filename))


def start():
    print "This program will create an animated gif image from the 30 images provided."

请编辑您的代码以包含错误和回溯。谢谢我可以说通过全局函数传递参数是一种真正的代码味道吗？请不要那样做。哦，天哪。那是我的错，我会加上它们。抱歉：/@Mark Ransom，那么什么是更合适的方法。将信息作为实际参数传递到函数中。尝试了上述错误，但仍然存在相同的错误。在我的mac中可以。你的错误是什么？如果仍然

IOError:encoder zip不可用

您可以检查以解决它。我上面的代码与stackoverflow post具有相同的推荐导入。并且它似乎仍然不起作用。以下是错误：我将错误添加到OP中。新错误：

TypeError:必须是字符串或缓冲区，而不是无
