# TTF\_SetFontKerning(3)

Set if kerning is enabled for a font.

## NAME

TTF\_SetFontKerning - Set if kerning is enabled for a font.

## HEADER FILE

Defined in SDL3\_ttf/SDL\_ttf.h

## SYNOPSIS

```
#include "SDL3_ttf/SDL_ttf.h"
```

**void TTF\_SetFontKerning(TTF\_Font \*font, bool enabled);**

## DESCRIPTION

Newly-opened fonts default to allowing kerning. This is generally a good policy unless you have a strong reason to disable it, as it tends to produce better rendering (with kerning disabled, some fonts might render the word **kerning** as something that looks like **keming** for example).

This updates any  **TTF\_Text**\
  objects using this font.

## FUNCTION PARAMETERS

- *font*

  the font to set kerning on.

- *enabled*

  true to enable kerning, false to disable.

## THREAD SAFETY

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

## AVAILABILITY

This function is available since SDL\_ttf 3.0.0.
