# Breaking: #102113 - Removed legacy setting 'GFX/gdlib' {#breaking-102113-1696697947}

See [forge#102113](https://forge.typo3.org/issues/102113)

## Description {#description}

'GFX/gdlib' is a setting that enables or disables image manipulation
using GDLib, functionality used in `GIFBUILDER`, depending if
the host system did not provide GDLib functionality.

With this change, the configuration value 'GFX/gdlib' has been removed, and
TYPO3 will simply check for the `GdImage` PHP class being available to
determine if it can be used.

## Impact {#impact}

TYPO3 now always enables GDLib functionality as soon as relevant GDLib classes
are found.

## Migration {#migration}

The configuration value has been removed without replacement.

Custom code that relied on `$GLOBALS['TYPO3_CONF_VARS']['GFX']['gdlib']`
should instead adopt the simpler check
`if (class_exists(\GdImage::class))`.
