sdlxGetTextureColorModFloat function render

bool sdlxGetTextureColorModFloat(Pointer<SdlTexture> texture, SdlxFColor color)

Get the additional color value multiplied into render copy operations.

\param texture the texture to query. \param r a pointer filled in with the current red color value. \param g a pointer filled in with the current green color value. \param b a pointer filled in with the current blue color value. \returns true on success or false on failure; call SDL_GetError() for more information.

\threadsafety This function should only be called on the main thread.

\since This function is available since SDL 3.2.0.
