sdlUpdateYuvTexture function

int sdlUpdateYuvTexture(Pointer<SdlTexture> texture, Pointer<SdlRect> rect, Pointer<Uint8> yplane, int ypitch, Pointer<Uint8> uplane, int upitch, Pointer<Uint8> vplane, int vpitch,)

Update a rectangle within a planar YV12 or IYUV texture with new pixel data.

You can use SDL_UpdateTexture() as long as your pixel data is a contiguous block of Y and U/V planes in the proper order, but this function is available if your pixel data is not contiguous.

\param texture the texture to update \param rect a pointer to the rectangle of pixels to update, or NULL to update the entire texture \param Yplane the raw pixel data for the Y plane \param Ypitch the number of bytes between rows of pixel data for the Y plane \param Uplane the raw pixel data for the U plane \param Upitch the number of bytes between rows of pixel data for the U plane \param Vplane the raw pixel data for the V plane \param Vpitch the number of bytes between rows of pixel data for the V plane \returns 0 on success or -1 if the texture is not valid; call SDL_GetError() for more information.

\since This function is available since SDL 2.0.1.
