# GFX - graphics configuration {#typo3confvars-gfx}

You can test the graphics configuration in module
**Environment > Image Processing**.
See also [Image processing test tool](https://docs.typo3.org/permalink/t3coreapi:environment-test-image-processing@13.4).

The following configuration variables can be used to configure settings for
the handling of images and graphics:

The configuration values listed here are keys in the global PHP array
`$GLOBALS['TYPO3_CONF_VARS']['GFX']`.

This variable can be set in one of the following files:

-   [config/system/settings.php](https://docs.typo3.org/permalink/t3coreapi:typo3confvars-settings@13.4)
-   [config/system/additional.php](https://docs.typo3.org/permalink/t3coreapi:typo3confvars-additional@13.4)

## thumbnails {#typo3confvars-gfx-thumbnails}

-   **thumbnails**

    -   *Type:* bool
    -   *Path:* $GLOBALS\['TYPO3_CONF_VARS'\]\['GFX'\]\['thumbnails'\]
    -   *Default:* true

    Enables the use of thumbnails in the backend interface.

## imagefile_ext {#typo3confvars-gfx-imagefile-ext}

-   **imagefile_ext**

    -   *Type:* list
    -   *Path:* $GLOBALS\['TYPO3_CONF_VARS'\]\['GFX'\]\['imagefile_ext'\]
    -   *Default:* 'gif,jpg,jpeg,tif,tiff,bmp,pcx,tga,png,pdf,ai,svg,webp'

    <!-- TODO: no Markdown rendering for "versionadded" -->

    "webp" has been added to the list of default image file extensions.If the underlying ImageMagick / GraphicsMagick library is not built with
    WebP support, the server administrators can install or recompile the library
    with WebP support by installing the "cwebp" or "dwebp" libraries.Comma-separated list of file extensions recognized as images by TYPO3.
    List should be set to `'gif,png,jpeg,jpg,webp'`, if ImageMagick /
    GraphicsMagick is not available.

    > [!WARNING]
    > **Caution**
    >
    > The file extensions must be in lowercase and there must be no spaces
    > between the commas and the file extensions!

## processor_enabled {#typo3confvars-gfx-processor-enabled}

    -   *Path:* $GLOBALS\['TYPO3_CONF_VARS'\]\['GFX'\]\['processor_allowFrameSelection'\]
    -   *Default:* true

    If set, the \[x\] frame selector is appended to input filenames in
    stdgraphic. This speeds up image processing for PDF files considerably.
    Disable if your image processor or environment cant cope with the
    frame selection.

## processor_stripColorProfileByDefault {#typo3confvars-gfx-processor-stripcolorprofilebydefault}

-   **processor_stripColorProfileByDefault**

    -   *Type:* bool
    -   *Path:* $GLOBALS\['TYPO3_CONF_VARS'\]\['GFX'\]\['processor_stripColorProfileByDefault'\]
    -   *Default:* true

    If set, the processor_stripColorProfileCommand is used with all processor
    image operations by default. See tsRef for setting this parameter explicitly
    for IMAGE generation.

## processor_stripColorProfileCommand {#typo3confvars-gfx-processor-stripcolorprofilecommand}

-   **processor_stripColorProfileCommand**

    -   *Type:* string
    -   *Path:* $GLOBALS\['TYPO3_CONF_VARS'\]\['GFX'\]\['processor_stripColorProfileCommand'\]

    > [!NOTE]
    > This string-based configuration option has been superseded by
    > [$GLOBALS\['TYPO3_CONF_VARS'\]\['GFX'\]\['processor_stripColorProfileParameters'\]](https://docs.typo3.org/permalink/t3coreapi:typo3confvars-gfx-processor-stripcolorprofileparameters@13.4)
    > for [security reasons](https://typo3.org/security/advisory/typo3-core-sa-2024-002).

    This option expected a string of command line parameters. The defined
    parameters had to be shell-escaped beforehand, while the new option
    [processor_stripColorProfileParameters](https://docs.typo3.org/permalink/t3coreapi:typo3confvars-gfx-processor-stripcolorprofileparameters@13.4) expects
    an array of strings that will be shell-escaped by TYPO3 when used.

    The existing configuration will continue to be supported. Still, it is
    suggested to use the new configuration format, as the Install Tool is
    adapted to allow modification of the new configuration option only:

    ```php
    // Before
    $GLOBALS['TYPO3_CONF_VARS']['GFX']['processor_stripColorProfileCommand'] = '+profile \'*\'';

    // After
    $GLOBALS['TYPO3_CONF_VARS']['GFX']['processor_stripColorProfileParameters'] = [
        '+profile',
        '*'
    ];
    ```

## processor_stripColorProfileParameters {#typo3confvars-gfx-processor-stripcolorprofileparameters}

-   **processor_stripColorProfileParameters**

    -   *Type:* array of strings
    -   *Path:* $GLOBALS\['TYPO3_CONF_VARS'\]\['GFX'\]\['processor_stripColorProfileParameters'\]
    -   *Default:* `['+profile', '*']`

    Specifies the parameters to strip the profile information, which can reduce
    thumbnail size up to 60KB. Command can differ in IM/GM, IM also knows the
    `-strip` command. See
    [imagemagick.org](https://legacy.imagemagick.org/Usage/thumbnails/#profiles)
    for details.

## processor_colorspace {#typo3confvars-gfx-processor-colorspace}

-   **processor_colorspace**

    -   *Type:* text
    -   *Path:* $GLOBALS\['TYPO3_CONF_VARS'\]\['GFX'\]\['processor_colorspace'\]
    -   *Default:* ''

    <!-- TODO: no Markdown rendering for "versionchanged" -->

    The setting defaults to an empty value and - if not changed - is adjusted
    automatically to the recommended colorspace for the given processor ("sRGB"
    for ImageMagick, "RGB" for GraphicsMagick).Specifies the colorspace to use. Defaults to "RGB" when using GraphicsMagick
    as [processor](https://docs.typo3.org/permalink/t3coreapi:typo3confvars-gfx-processor@13.4) and "sRGB" when using
    ImageMagick.

    > [!NOTE]
    > Images would be rendered darker than the original when using ImageMagick
    > in combination with "RGB".

    Possible values: CMY, CMYK, Gray, HCL, HSB, HSL, HWB, Lab, LCH, LMS, Log,
    Luv, OHTA, Rec601Luma, Rec601YCbCr, Rec709Luma, Rec709YCbCr, RGB, sRGB,

-   **processor_interlace**

    -   *Type:* text
    -   *Path:* $GLOBALS\['TYPO3_CONF_VARS'\]\['GFX'\]\['processor_interlace'\]
    -   *Default:* 'None'

    Specifies the interlace option to use. The result differs in different
    GM / IM versions. See manual of GraphicsMagick or ImageMagick for
    right option.

    Possible values: None, Line, Plane, Partition

## jpg_quality {#typo3confvars-gfx-jpg-quality}

-   **jpg_quality**

    -   *Type:* int
    -   *Path:* $GLOBALS\['TYPO3_CONF_VARS'\]\['GFX'\]\['jpg_quality'\]
    -   *Default:* 85
    -   *Allowed values:* Between 1 (low quality, small file size) and 100 (best quality, large file size)

    <!-- TODO: no Markdown rendering for "versionadded" -->

    Lowest quality can be "1". Previously the lowest quality setting was "10".Default JPEG generation quality

## webp_quality {#typo3confvars-gfx-webp-quality}

-   **webp_quality**

    -   *Type:* int | string
    -   *Path:* $GLOBALS\['TYPO3_CONF_VARS'\]\['GFX'\]\['webp_quality'\]
    -   *Default:* 85
    -   *Allowed values:* Between 1 (low quality, small file size) and 100 (best quality, large file size), or "lossless"

    <!-- TODO: no Markdown rendering for "versionadded" -->

    Default WebP generation quality. Setting the quality to "lossless"
    is equivalent to ["lossless" compression](https://developers.google.com/speed/webp/docs/compression#lossless_webp).

-   **thumbnails_png**

    -   *Path:* $GLOBALS\['TYPO3_CONF_VARS'\]\['GFX'\]\['thumbnails_png'\]

    <!-- TODO: no Markdown rendering for "versionchanged" -->

    This setting has been removed. Thumbnails from non-image files (like
    PDF) are always generated as PNG.

-   **gif_compress**

    -   *Path:* $GLOBALS\['TYPO3_CONF_VARS'\]\['GFX'\]\['gif_compress'\]

    <!-- TODO: no Markdown rendering for "versionchanged" -->

    This setting has been removed.

-   **processor_allowTemporaryMasksAsPng**

    -   *Path:* $GLOBALS\['TYPO3_CONF_VARS'\]\['GFX'\]\['processor_allowTemporaryMasksAsPng'\]

    <!-- TODO: no Markdown rendering for "versionchanged" -->

    This setting has been removed. Temporarily saved masking images are
    always saved as PNG files rather than GIF images.

-   **gdlib**

    -   *Path:* $GLOBALS\['TYPO3_CONF_VARS'\]\['GFX'\]\['gdlib'\]

    <!-- TODO: no Markdown rendering for "versionchanged" -->

    This setting has been removed. GDLib functionality is enabled as soon as
    relevant GDLib classes are found.Custom code that relied on $GLOBALS['TYPO3_CONF_VARS']['GFX']['gdlib']
    should instead adopt the simpler check
    if (class_exists(\GdImage::class)).

-   **gdlib_png**

    -   *Path:* $GLOBALS\['TYPO3_CONF_VARS'\]\['GFX'\]\['gdlib_png'\]

    <!-- TODO: no Markdown rendering for "versionchanged" -->

    This setting has been removed. Temporary layers/masks are always saved
    as PNG files instead of GIF files.
