Font not displaying in the P4 Led but the program is running

[robinsonkarunya]

I'm not getting output in led pannel but the program is running
This is the program :
import time
from rgbmatrix import RGBMatrix, RGBMatrixOptions, graphics

---------- Setup LED Matrix ----------

options = RGBMatrixOptions()
options.rows = 40
options.cols = 80
options.chain_length = 2
options.parallel = 1
options.multiplexing = 20
options.gpio_slowdown = 4
options.hardware_mapping = 'regular'

matrix = RGBMatrix(options=options)
canvas = matrix.CreateFrameCanvas()

---------- Static Text Display Function ----------

def display_static_text():
font = graphics.Font()
font.LoadFont("/home/pi/rpi-rgb-led-matrix/fonts/smallfont.bdf") # Larger font
font_height = font.height

text = "Magneto Dynamics"
text_color = graphics.Color(255, 255, 0)

# Get text width to center it
text_width = graphics.DrawText(canvas, font, 0, 0, text_color, text)
x_pos = (canvas.width - text_width) // 2
y_pos = ((canvas.height - font_height) // 2) + font_height

canvas.Clear()
graphics.DrawText(canvas, font, x_pos, y_pos, text_color, text)
matrix.SwapOnVSync(canvas)

---------- Main ----------

try:
display_static_text()
while True:
time.sleep(1) # Keeps running to hold the display
except KeyboardInterrupt:
print("Stopped.")
canvas.Clear()
matrix.SwapOnVSync(canvas)

This is terminal output 👍 :
python new2.py
FYI: not running as root which means we can't properly control timing unless this is a real-time kernel. Expect color degradation. Consider running as root with sudo.
