sdlRenderTexture function render

bool sdlRenderTexture(Pointer<SdlRenderer> renderer, Pointer<SdlTexture> texture, Pointer<SdlFRect> srcrect, Pointer<SdlFRect> dstrect,)

Copy a portion of the texture to the current rendering target at subpixel precision.

\param renderer the renderer which should copy parts of a texture. \param texture the source texture. \param srcrect a pointer to the source rectangle, or NULL for the entire texture. \param dstrect a pointer to the destination rectangle, or NULL for the entire rendering target. \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.
