# SDL\_UpdateNVTexture(3)

Update a rectangle within a planar NV12 or NV21 texture with new pixels.

## NAME

SDL\_UpdateNVTexture - Update a rectangle within a planar NV12 or NV21 texture with new pixels.

## HEADER FILE

Defined in SDL3/SDL\_render.h

## SYNOPSIS

```
#include "SDL3/SDL.h"
```

**bool SDL\_UpdateNVTexture(SDL\_Texture \*texture,**                      **const SDL\_Rect \*rect,**                      **const Uint8 \*Yplane, int Ypitch,**                      **const Uint8 \*UVplane, int UVpitch);**

## DESCRIPTION

You can use  **SDL\_UpdateTexture** () as long as your pixel data is a contiguous block of NV12/21 planes in the proper order, but this function is available if your pixel data is not contiguous.

## FUNCTION PARAMETERS

- *texture*

  the texture to update.

- *rect*

  a pointer to the rectangle of pixels to update, or NULL to update the entire texture.

- *Yplane*

  the raw pixel data for the Y plane.

- *Ypitch*

  the number of bytes between rows of pixel data for the Y plane.

- *UVplane*

  the raw pixel data for the UV plane.

- *UVpitch*

  the number of bytes between rows of pixel data for the UV plane.

## RETURN VALUE

Returns true on success or false on failure; call

**SDL\_GetError** () for more information.

## THREAD SAFETY

This function should only be called on the main thread.

## AVAILABILITY

This function is available since SDL 3.2.0.
