I can't use "graphics.DrawText" with "matrix.SetPixel()" without parasite

[XomaFR]

Sorry for my english ^^', My matrix (64x32) is controlled by my raspberry pi4 and hat adafruit. I'm using rpi-rgb-led-matrix/bindings/python/samples/runtext.py to create Clock.py.

`#!/usr/bin/env python

Cette matrice affiche l'heure et la date en étant synchroniser avec la machine qui l'éxécute.

from samplebase import SampleBase from rgbmatrix import graphics, RGBMatrix, RGBMatrixOptions from datetime import datetime, timedelta import time

class Clock(SampleBase): def init(self, *args, *kwargs): super(Clock, self).init(args, **kwargs)

def run(self):
    offscreen_canvas = self.matrix.CreateFrameCanvas()
    font = graphics.Font()
    font.LoadFont("/home/pi/rgb/rpi-rgb-led-matrix/fonts/5x8.bdf")
    textColor = graphics.Color(255, 255, 0)
    pos = offscreen_canvas.width
    while True:
        offscreen_canvas.Clear()
        HMS=datetime.now() + timedelta(seconds=1)
        Heure = HMS.strftime('%H:%M:%S')
        Date=datetime.now().strftime('%d/%m/%Y')
        Jour=datetime.today()
        listejour=["Lun", "Mar", "Mer", "Jeu", "Ven", "Sam", "Dim"]
        Jour=listejour[Jour.weekday()]
        warning(59,26,True)
        graphics.DrawText(offscreen_canvas, font, 0, 6, textColor, Jour)
        graphics.DrawText(offscreen_canvas, font, 15, 6, textColor, Date)
        graphics.DrawText(offscreen_canvas, font, 0, 32, textColor, Heure)
        time.sleep(1)
        offscreen_canvas = self.matrix.SwapOnVSync(offscreen_canvas)

Main function

if name == "main": clock = Clock() if (not clock.process()): clock.print_help() `

Result:

I want to add warning symbol with function matrix.SetPixel(). But when i add "Configuration for the matrix" to define the function matrix. My screen display a parasite and the text flashes:

So i don't understand how configure to use graphic with setpixel. Thank for your help and good day :)

This problem is solve i have replace matrix.setPixel by graphics.DrawLine
