Description

Gets a single pixel colour from the miniwindow.

WindowName - the name of an existing miniwindow.

x, y - the location of the pixel (x is horizontal, y is vertical)


Note that after doing a WindowSetPixel, if you do a WindowGetPixel you will not necessarily get back the same value, particularly if the screen monitor resolution is set to 16 bit colour or less.


Note: Available in version 4.36 onwards.


Lua example
c = WindowGetPixel (win, 2, 3)
Returns -1 if the pixel is out of the range of the window size.

-2 if the miniwindow does not exist.

Otherwise: The colour at that location as an RGB code.
Introduced in version 4.36
