sdlSetRenderDrawColor function render

bool sdlSetRenderDrawColor(Pointer<SdlRenderer> renderer, int r, int g, int b, int a,)

Set the color used for drawing operations.

Set the color for drawing or filling rectangles, lines, and points, and for SDL_RenderClear().

\param renderer the rendering context. \param r the red value used to draw on the rendering target. \param g the green value used to draw on the rendering target. \param b the blue value used to draw on the rendering target. \param a the alpha value used to draw on the rendering target; usually SDL_ALPHA_OPAQUE (255). Use SDL_SetRenderDrawBlendMode to specify how the alpha channel is used. \returns true on success or false on failure; call SDL_GetError() for more information.

\threadsafety This function should only be called on the main thread.

\since This function is available since SDL 3.2.0.
