Set an additional color value multiplied into render copy operations.
int SDL_SetTextureColorMod(SDL_Texture * texture, Uint8 r, Uint8 g, Uint8 b);
|texture||the texture to update|
|r||the red color value multiplied into copy operations|
|g||the green color value multiplied into copy operations|
|b||the blue color value multiplied into copy operations|
Returns 0 on success or a negative error code on failure; call SDL_GetError() for more information.
When this texture is rendered, during the copy operation each source color channel is modulated by the appropriate color value according to the following formula:
srcC = srcC * (color / 255)
Color modulation is not always supported by the renderer; it will return -1 if color modulation is not supported.
This function is available since SDL 2.0.0.
