Comparison of rendering speeds of several toolkits and wx

Two points in addition.

  1. I modified it as follows,
-    wx.BufferedPaintDC(self.panel, self.bitmap)
+    dc = wx.BufferedPaintDC(self.panel, self.bitmap)

I attach the last modified files. I hope these would help people who want to start dealing with images.

  1. Someone may want to use wx GUI and pyqtgraph function lIke this.
import wx
import numpy as np
import pyqtgraph as pg
from pyqtgraph.Qt import QtCore, QtGui

class Frame(wx.Frame):
    def __init__(self, *args, **kwargs):
        super().__init__(*args, **kwargs)
        
        self.btn = wx.Button(self, label="Press me")
        self.btn.Bind(wx.EVT_BUTTON, self.run)
    
    def run(self, evt):
        self.qfrm = pg.GraphicsLayoutWidget(title=self.__module__)
        image = pg.ImageItem() # create image
        view = self.qfrm.addViewBox() # create view
        view.setAspectLocked(True)
        view.addItem(image)
        
        def update():
            h, w = 768, 1152
            src = (255 * np.random.rand(h, w)).astype(np.uint8)
            image.setImage(src.T)
        
        timer = QtCore.QTimer()
        timer.timeout.connect(update)
        timer.start()
        
        self.qfrm.show()
        pg.exec()

if __name__ == "__main__":
    qApp = QtGui.QApplication()
    app = wx.App()
    frm = Frame(None)
    frm.Show()
    app.MainLoop()
