如何将图像保存或打印到在wxPanel上绘制的wxPython文件中

import wx

class MyPanel(wx.Panel):
    def __init__(self, parent):
        wx.Panel.__init__(self, parent)
        
    def paint(self, event):
        dc = wx.PaintDC(self)
        # 在此处进行图像的绘制操作
        # 例如：dc.DrawBitmap(bitmap, x, y, useMask=False)

class MyFrame(wx.Frame):
    def __init__(self, parent):
        wx.Frame.__init__(self, parent, title="Image Printing")
        panel = MyPanel(self)
        self.Bind(wx.EVT_PAINT, panel.paint)

bitmap = wx.Bitmap("image.jpg", wx.BITMAP_TYPE_ANY)

dc.DrawBitmap(bitmap, x, y, useMask=False)

def save_image(event):
    # 保存图像的代码

def print_image(event):
    # 打印图像的代码

save_button = wx.Button(self, label="Save Image")
self.Bind(wx.EVT_BUTTON, save_image, save_button)

print_button = wx.Button(self, label="Print Image")
self.Bind(wx.EVT_BUTTON, print_image, print_button)

image = bitmap.ConvertToImage()
image.SaveFile("saved_image.jpg", wx.BITMAP_TYPE_JPEG)

class ImagePrintout(wx.Printout):
    def OnPrintPage(self, page):
        dc = self.GetDC()
        dc.DrawBitmap(bitmap, x, y)
        return True

def print_image(event):
    printer = wx.Printer()
    printout = ImagePrintout()
    printer.Print(self, printout)
