# IMG\_LoadTexture\_IO(3)

Load an image from an SDL data source into a GPU texture.

## NAME

IMG\_LoadTexture\_IO - Load an image from an SDL data source into a GPU texture.

## HEADER FILE

Defined in SDL3\_image/SDL\_image.h

## SYNOPSIS

```
#include "SDL3_image/SDL_image.h"
```

**SDL\_Texture \* IMG\_LoadTexture\_IO(SDL\_Renderer \*renderer, SDL\_IOStream \*src, bool closeio);**

## DESCRIPTION

An SDL\_Texture represents an image in GPU memory, usable by SDL's 2D Render API. This can be significantly more efficient than using a CPU-bound SDL\_Surface if you don't need to manipulate the image directly after loading it.

If the loaded image has transparency or a colorkey, a texture with an alpha channel will be created. Otherwise, SDL\_image will attempt to create an SDL\_Texture in the most format that most reasonably represents the image data (but in many cases, this will just end up being 32-bit RGB or 32-bit RGBA).

If **closeio** is true, **src** will be closed before returning, whether this function succeeds or not. SDL\_image reads everything it needs from **src** during this call in any case.

There is a separate function to read files from disk without having to deal with SDL\_IOStream: **IMG\_LoadTexture(renderer,**filename.jpg**)** will call this function and manage those details for you, determining the file type from the filename's extension.

There is also  **IMG\_LoadTextureTyped\_IO** (), which is equivalent to this function except a file extension (like "BMP", "JPG", etc) can be specified, in case SDL\_image cannot autodetect the file format.

If you would rather decode an image to an SDL\_Surface (a buffer of pixels in CPU memory), call  **IMG\_Load** () instead.

When done with the returned texture, the app should dispose of it with a call to SDL\_DestroyTexture().

## FUNCTION PARAMETERS

- *renderer*

  the SDL\_Renderer to use to create the GPU texture.

- *src*

  an SDL\_IOStream that data will be read from.

- *closeio*

  true to close/free the SDL\_IOStream before returning, false to leave it open.

## RETURN VALUE

Returns a new texture, or NULL on error.

## AVAILABILITY

This function is available since SDL\_image 3.0.0.
