no errors

尝试解决过程

using RGB565 as the image format works, but why not RGB888 and ARGB8888?

from media.display import *
import time,os
try:
    DISPLAY_WIDTH = 64
    DISPLAY_HEIGHT = 64
    width = DISPLAY_WIDTH
    height = DISPLAY_HEIGHT
    img = image.Image(width,height,image.RGB565)
#    img = image.Image(width,height,image.RGB888)
#    img = image.Image(width,height,image.ARGB8888)
    img.clear()
    img.draw_line(-10, -10, 10, 10, color=(255,255,255), thickness=10)
    img.draw_image(img, 32, 32, x_scale=1, y_scale=1)
    if img.format()==image.RGB888:
        print("RGB888")
    elif img.format()==image.ARGB8888:
        print("ARGB8888")
    elif img.format()==image.RGB565:
        print("RGB565")
    else:
        print(f"unknown {img.format()}")

    Display.init(Display.VIRT, width=DISPLAY_WIDTH, height=DISPLAY_HEIGHT, fps=60)
    MediaManager.init()
    Display.show_image(img)
    time.sleep_ms(100)
finally:
    Display.deinit()
    os.exitpoint(os.EXITPOINT_ENABLE_SLEEP)
    time.sleep_ms(100)
    MediaManager.deinit()
