Question

是否有办法在Tkinter利用Adhur图像图书馆展示一个消化的全球信息论坛?

我想ImageSequence 模块是这样做的途径,但我不知道如何使用,如果可能的话。

第一个问题是,是否容易。例如:使用PIL和图像Sequence装设一个全球电子数据系统,然后使用<代码>ImageTk.PhotoImage将其提用一个Tkinter窗口。

或者,我是否必须利用<条码>之后的<条码>方法,或者像<条码> 时间.sleep

第二个问题:即使我必须履行通过全球投资论坛框架的职能,图像数据模块是否应该这样做,或者消费物价指数是否拥有另一个模块?

Daniel Nogradi写道:

The source distribution of the 1.1.4 version comes with a Scripts directory where you can find player.py, gifmaker.py and explode.py which all deal with animated gif.

他们仍用1.1.5(和1.1.6)重新运输,应当工作。

if all you re missing is a few files from the script directory, you can get them here:

see if this one works for you:

from Tkinter import * 
from PIL import Image, ImageTk


class MyLabel(Label):
    def __init__(self, master, filename):
        im = Image.open(filename)
        seq =  []
        try:
            while 1:
                seq.append(im.copy())
                im.seek(len(seq)) # skip to next frame
        except EOFError:
            pass # we re done

        try:
            self.delay = im.info[ duration ]
        except KeyError:
            self.delay = 100

        first = seq[0].convert( RGBA )
        self.frames = [ImageTk.PhotoImage(first)]

        Label.__init__(self, master, image=self.frames[0])

        temp = seq[0]
        for image in seq[1:]:
            temp.paste(image)
            frame = temp.convert( RGBA )
            self.frames.append(ImageTk.PhotoImage(frame))

        self.idx = 0

        self.cancel = self.after(self.delay, self.play)

    def play(self):
        self.config(image=self.frames[self.idx])
        self.idx += 1
        if self.idx == len(self.frames):
            self.idx = 0
        self.cancel = self.after(self.delay, self.play)        


root = Tk()
anim = MyLabel(root,  animated.gif )
anim.pack()

def stop_it():
    anim.after_cancel(anim.cancel)

Button(root, text= stop , command=stop_it).pack()

root.mainloop()

Answer 2

简略版本:

canvas = Image.new("RGB",(Width,Height),"white")
gif = Image.open( text.gif ,  r )
frames = []
try:
    while 1:
        frames.append(gif.copy())
        gif.seek(len(frames))
except EOFError:
    pass

for frame in frames:
     canvas.paste(frame)
     canvas.show()
