sdlRenderCopy function

int sdlRenderCopy(
  1. Pointer<SdlRenderer> renderer,
  2. Pointer<SdlTexture> texture,
  3. Pointer<SdlRect> srcrect,
  4. Pointer<SdlRect> dstrect,
)

Copy a portion of the texture to the current rendering target.

The texture is blended with the destination based on its blend mode set with SDL_SetTextureBlendMode().

The texture color is affected based on its color modulation set by SDL_SetTextureColorMod().

The texture alpha is affected based on its alpha modulation set by SDL_SetTextureAlphaMod().

\param renderer the rendering context \param texture the source texture \param srcrect the source SDL_Rect structure or NULL for the entire texture \param dstrect the destination SDL_Rect structure or NULL for the entire rendering target; the texture will be stretched to fill the given rectangle \returns 0 on success or a negative error code on failure; call SDL_GetError() for more information.

\since This function is available since SDL 2.0.0.
