(

std::initializer_list< int >

values

)

Assigns rgb values to the pixel.

If an empty initializer_list is given, the pixel is set to black. If a single value is given, it is assigned to r, g and b (usefull for grey-scale images). If three values are given, they are assigned to r, g and b (in that order).

Parameters:

values
