SDL_SetTextureColorModFloat

Set an additional color value multiplied into render copy operations.

Header File

Syntax

bool SDL_SetTextureColorModFloat(SDL_Texture *texture, float r, float g, float b);

Function Parameters

SDL_Texture *	texture	the texture to update.
float	r	the red color value multiplied into copy operations.
float	g	the green color value multiplied into copy operations.
float	b	the blue color value multiplied into copy operations.

Return Value

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

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

Color modulation is not always supported by the renderer; it will return false if color modulation is not supported.

Thread Safety

You may only call this function from the main thread.

Version

This function is available since SDL 3.1.3.
