# SDL_CreateTextureFromSurface

Create a texture from an existing surface.

## Header File

Defined in [<SDL3/SDL_render.h>](https://github.com/libsdl-org/SDL/blob/main/include/SDL3/SDL_render.h)

## Syntax

```c
SDL_Texture * SDL_CreateTextureFromSurface(SDL_Renderer *renderer, SDL_Surface *surface);
```

## Function Parameters

|                                |              |                                                                                          |
| ------------------------------ | ------------ | ---------------------------------------------------------------------------------------- |
| [SDL_Renderer](SDL_Renderer) * | **renderer** | the rendering context.                                                                   |
| [SDL_Surface](SDL_Surface) *   | **surface**  | the [SDL_Surface](SDL_Surface) structure containing pixel data used to fill the texture. |

## Return Value

([SDL_Texture](SDL_Texture) *) Returns the created texture or NULL on
failure; call [SDL_GetError](SDL_GetError)() for more information.

## Remarks

The surface is not modified or freed by this function.

The [SDL_TextureAccess](SDL_TextureAccess) hint for the created texture is
[`SDL_TEXTUREACCESS_STATIC`](SDL_TEXTUREACCESS_STATIC).

The pixel format of the created texture may be different from the pixel
format of the surface, and can be queried using the
[SDL_PROP_TEXTURE_FORMAT_NUMBER](SDL_PROP_TEXTURE_FORMAT_NUMBER) property.

## Thread Safety

This function should only be called on the main thread.

## Version

This function is available since SDL 3.2.0.

## Code Examples

```c
SDL_Renderer *renderer;

SDL_Surface *surface = SDL_CreateSurface(640, 480, SDL_PIXELFORMAT_RGBA8888);

if (surface == NULL) {
    fprintf(stderr, "CreateRGBSurface failed: %s\n", SDL_GetError());
    exit(1);
}

SDL_Texture *texture = SDL_CreateTextureFromSurface(renderer, surface);

if (texture == NULL) {
    fprintf(stderr, "CreateTextureFromSurface failed: %s\n", SDL_GetError());
    exit(1);
}

SDL_DestroySurface(surface);
surface = NULL;
```
