Syntax
int SDL_SetTextureColorMod(SDL_Texture* texture,
                           Uint8        r,
                           Uint8        g,
                           Uint8        b)
Function Parameters
| 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 | 
Return Value
Returns 0 on success or a negative error code on failure; call SDL_GetError() for more information.
Code Examples
...
SDL_Texture* pTexture = SDL_CreateTextureFromSurface( renderer, loadedSurface );
SDL_SetTextureColorMod( pTexture, 64, 64, 64 );
...
Remarks
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.
