Pysimplegui在图形中使用gif

Question

我试图在我的pysimplegui图形中使用gif，但gif不移动，有什么方法可以解决这个问题?我看到有一种方法来更新动画，但我不能抓取图形图像来更新它，所以我能做什么?而且我的屏幕读取没有阻塞任何东西

def criapersonagem(x,y):
global local_personagem
global personagem
personagem = graph.draw_image(filename='personagemgif.gif',
data=None,
location=(x, y))
criarpersonagem(90,60)

这就是我在图表

中创建图像的方法

GIF图像中有很多帧，对于动画来说，你必须让每一帧随着时间的推移而显示。

这里有一个例子来说明我是怎么做的。键盘控制，<Left><Right><Up><Down>，也工作。请记住在代码中使用GIF文件。

import ctypes
import platform
import threading
from io import BytesIO
from time import sleep
from PIL import Image
import PySimpleGUI as sg
def image_to_data(im):
with BytesIO() as output:
im.save(output, format="PNG")
data = output.getvalue()
return data
def process_thread():
global index
while True:
sleep(0.01)
index = (index + 1) % frames
window.write_event_value('Animation', index)
if platform.system() == "Windows":
if platform.release() == "7":
ctypes.windll.user32.SetProcessDPIAware()
elif platform.release() == "8" or platform.release() == "10":
ctypes.windll.shcore.SetProcessDpiAwareness(1)
im = Image.open("D:/1.gif")
width, height = im.size
frames = im.n_frames
graph_width, graph_height = size = (640, 640)
layout = [[sg.Graph(size, (0, 0), size, background_color='green', key='GRAPH')]]
window = sg.Window("Animation", layout, return_keyboard_events=True, finalize=True)
graph = window['GRAPH']
index = 0
im.seek(index)
data = image_to_data(im)
x, y = location = (graph_width//2-width//2, height)
item = graph.draw_image(data=data, location=location)
step = 20
thread = threading.Thread(target=process_thread, daemon=True)
thread.start()
while True:
event, values = window.read(timeout=50)
if event == sg.WINDOW_CLOSED:
break
elif event == 'Animation':
im.seek(index)
data = image_to_data(im)
item_new = graph.draw_image(data=data, location=location)
graph.delete_figure(item)
item = item_new
elif event == "Left:37":
x = x - step if x >= step else x
location = (x, y)
elif event == "Right:39":
x = x + step if x <= graph_width - width - step else x
location = (x, y)
elif event == "Up:38":
y = y + step if y <= graph_height - step else y
location = (x, y)
elif event == "Down:40":
y = y - step if y >= height + step else y
location = (x, y)
window.close()
