SDL_SetSurfaceColorMod - Man Page

#include <SDL3/SDL_surface.h>

bool SDL_SetSurfaceColorMod(SDL_Surface *surface, Uint8 r, Uint8 g, Uint8 b);

When this surface is blitted, during the blit operation each source color channel is modulated by the appropriate color value according to the following formula:

srcC = srcC * (color / 255)

surface

the SDL_Surface structure to update.

r

the red color value multiplied into blit operations.

g

the green color value multiplied into blit operations.

b

the blue color value multiplied into blit operations.

Returns true on success or false on failure; call SDL_GetError() for more information.

This function can be called on different threads with different surfaces.

This function is available since SDL 3.2.0.
