Pysimplegui 在图中使用 gif

Question

Im trying to use gifs in my pysimplegui graph, but the gif dont move, there is any way to fix that? I saw that there is a way to update animations, but i cant grab the graph image to update it, so what can i do? Also my screen read isnt blocking anything

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

thats how i created the image in the graph

There're lot of frames in a GIF image, for animation, you have to get each frame shown as time passed.

Here's example to show how I do it. Keyboard control, <Left><Right><Up><Down> , also work. Remember to use your GIF file in code.

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()
