pysimplegui Canvas 打开bmp格式

您可以使用Pillow库（也称为PIL）将BMP文件打开为Pysimplegui Canvas。

下面是一个示例代码，它使用Canvas和Pillow将BMP图像打开并绘制到GUI上：

import PySimpleGUI as sg
from PIL import ImageTk, Image

# define the GUI layout
layout = [[sg.Canvas(size=(300,300), key='-CANVAS-')]]

# create the GUI window
window = sg.Window('BMP Image Viewer', layout)

# open the BMP image with PIL
bmp_image = Image.open('image.bmp')

# convert the BMP image to TKimage for use in Pysimplegui Canvas
tk_image = ImageTk.PhotoImage(bmp_image)

# get the Canvas element
canvas = window['-CANVAS-'].TKCanvas

# draw the TKimage on the Canvas
canvas.create_image(0, 0, anchor='nw', image=tk_image)

# display the GUI window and loop through events
while True:
    event, values = window.read()
    if event == sg.WINDOW_CLOSED:
        break

# close the GUI window
window.close()

在运行此代码之前，请确保已安装Pysimplegui和Pillow库并将BMP图像文件放置在当前工作目录中。
