Does LCD has the function of readPixel in Micropython?

[Zorky]

Hello,now i hold a M5paper.I want to shot the E-ink screen.But i cant find a function about reading pixel in LCD.Is it?

By the way,i tried to create another framebuffer(MONO_HMSB) to synchronize lcd.but it cant work when i use the function of framebuffer.rect(x,y,0) or others and writing it to bmp file by framebuffer.pixel(x,y).Could anyone know the reason why?Thank you!
