SDL_SetTextureColorMod
Use this function to set an additional color value multiplied into render copy operations.
Contents
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_Surface 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.
