sdlRenderCopyEx function

int sdlRenderCopyEx(
  1. Pointer<SdlRenderer> renderer,
  2. Pointer<SdlTexture> texture,
  3. Pointer<SdlRect> srcrect,
  4. Pointer<SdlRect> dstrect,
  5. double angle,
  6. Pointer<SdlPoint> center,
  7. int flip,
)

Copy a portion of the texture to the current rendering, with optional rotation and flipping.

Copy a portion of the texture to the current rendering target, optionally rotating it by angle around the given center and also flipping it top-bottom and/or left-right.

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 \param angle an angle in degrees that indicates the rotation that will be applied to dstrect, rotating it in a clockwise direction \param center a pointer to a point indicating the point around which dstrect will be rotated (if NULL, rotation will be done around dstrect.w / 2, dstrect.h / 2) \param flip a SDL_RendererFlip value stating which flipping actions should be performed on the texture \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.
