## Return Value

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

## Remarks

Color and alpha modulation is done per vertex
([SDL_SetTextureColorMod](SDL_SetTextureColorMod) and
[SDL_SetTextureAlphaMod](SDL_SetTextureAlphaMod) are ignored).

## Thread Safety

This function should only be called on the main thread.

## Version

This function is available since SDL 3.2.0.
