pget( x, y )
- Gets the color value of a pixel at the given coordinates.
- x
-
- The x coordinate.
- y
-
- The y coordinate.
The pget()
function reads the color value of a pixel from the graphics buffer.
It will read from the buffer even if the buffer has not yet been copied to the display.
It will return 0 (black) if given coordinates outside the range (0-127,0-127).
Examples[]
pset(10, 10, 7) -- sets (10, 10) to white
print(pget(10, 10), 0, 112, 7) -- prints 7
pset(10, 10, 8) -- sets (10, 10) to red
print(pget(10, 10), 0, 120, 7) -- prints 8
flip() -- displays the red (8) pixel and the messages
