# TTF_GetGLTextDrawData

Get the geometry data needed for drawing the text.

## Header File

Defined in [<SDL3_ttf/SDL_ttf.h>](https://github.com/libsdl-org/SDL_ttf/blob/main/include/SDL3_ttf/SDL_ttf.h)

## Syntax

```c
TTF_GLAtlasDrawSequence * TTF_GetGLTextDrawData(TTF_Text *text);
```

## Function Parameters

|                        |          |                   |
| ---------------------- | -------- | ----------------- |
| [TTF_Text](TTF_Text) * | **text** | the text to draw. |

## Return Value

([TTF_GLAtlasDrawSequence](TTF_GLAtlasDrawSequence) *) Returns a NULL
terminated linked list of
[TTF_GLAtlasDrawSequence](TTF_GLAtlasDrawSequence) objects or NULL if the
passed text is empty or in case of failure; call SDL_GetError() for more
information.

## Remarks

`text` must have been created using a [TTF_TextEngine](TTF_TextEngine) from
[TTF_CreateGLTextEngine](TTF_CreateGLTextEngine)().

The positive X-axis is taken towards the right and the positive Y-axis is
taken upwards for both the vertex and the texture coordinates, i.e, it
follows the same convention used by the OpenGL API. If you want to use a
different coordinate system you will need to transform the vertices
yourself.

If the text looks blocky use linear filtering.

## Thread Safety

This function should be called on the thread that created the text.

## Version

This function is available since SDL_ttf 3.3.0.
