Contents
Availability
This function is available since SDL 3.2.0.
Simple Directmedia Layer SDL 3.2.10 SDL_WriteSurfacePixel(3)
Description
This function prioritizes correctness over speed: it is suitable for unit tests, but is not intended for
use in a game engine.
Like SDL_MapRGBA , this uses the entire 0..255 range when converting color components from pixel formats
with less than 8 bits per RGB component.
Function Parameters
surface
the surface to write.
x the horizontal coordinate, 0 <= x < width.
y the vertical coordinate, 0 <= y < height.
r the red channel value, 0-255.
g the green channel value, 0-255.
b the blue channel value, 0-255.
a the alpha channel value, 0-255.
