LightX API -> lxgfx -> getpixel

lxgfx.getpixel


function getpixel(
  surface: tlxhandle;
  x, y: tlxposition;
): tlxcolour32;


Return the colour of a pixel at the given co-ordinates.

If you will be reading a lot of pixels, consider locking the surface and directly manipulating it's image buffer instead. Calling getpixel repeatedly is very slow since it must lock and unlock the surface for every pixel read and there is the overhead of one function call per pixel too.

surface: tlxhandle
The surface to read from.

x, y: tlxposition
The X,Y co-ordinates to read from.

Class: lxgfx
