GFX - graphics configuration

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

Note

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:

thumbnails

$GLOBALS['TYPO3_CONF_VARS']['GFX']['thumbnails']

type: bool
Default: true

Enables the use of thumbnails in the backend interface.

thumbnails_png

$GLOBALS['TYPO3_CONF_VARS']['GFX']['thumbnails_png']

type: bool
Default: true

If disabled, thumbnails from non-image files will be converted to gif, otherwise png (default).

gif_compress

$GLOBALS['TYPO3_CONF_VARS']['GFX']['gif_compress']

type: bool
Default: true

Enables the use of the \TYPO3\CMS\Core\Imaging\GraphicalFunctionsgifCompress() workaround function for compressing .gif files made with GD or IM, which probably use only RLE or no compression at all.

imagefile_ext

$GLOBALS['TYPO3_CONF_VARS']['GFX']['imagefile_ext']

type: list
Default: 'gif,jpg,jpeg,tif,tiff,bmp,pcx,tga,png,pdf,ai,svg'

Comma-separated list of file extensions perceived as images by TYPO3. List should be set to 'gif,png,jpeg,jpg' if IM is not available. Lowercase and no spaces between!

gdlib

$GLOBALS['TYPO3_CONF_VARS']['GFX']['gdlib']

type: bool
Default: true

Enables the use of GD.

gdlib_png

$GLOBALS['TYPO3_CONF_VARS']['GFX']['gdlib_png']

type: bool
Default: false

Enables the use of GD, with PNG only. This means that all items normally generated as gif-files will be png-files instead!

processor_enabled

$GLOBALS['TYPO3_CONF_VARS']['GFX']['processor_enabled']

type: bool
Default: true

Enables the use of Image- or GraphicsMagick.

processor_path

$GLOBALS['TYPO3_CONF_VARS']['GFX']['processor_path']

type: text
Default: '/usr/bin/'

Path to the IM tools convert, combine, identify.

$GLOBALS['TYPO3_CONF_VARS']['GFX']['processor_path_lzw']

processor_path_lzw

Path: $GLOBALS['TYPO3_CONF_VARS']['GFX']
type: text
Default: '/usr/bin/'

Path to the IM tool convert with LZW enabled! See gif_compress. If your version 4.2.9 of ImageMagick is compiled with LZW you may leave this field blank AND disable the flag gif_compress.

Tip

You can call LZW convert with a prefix like myver_convert by setting this path with it, eg. '/usr/bin/myver_' instead of just '/usr/bin/'.

processor

$GLOBALS['TYPO3_CONF_VARS']['GFX']['processor']

type

dropdown

Default

'ImageMagick'

allowedValues

ImageMagick: Choose ImageMagick for processing images
GraphicsMagick: Choose GraphicsMagick for processing images

Select which external software on the server should process images - see also the preset functionality to see what is available.

processor_effects

$GLOBALS['TYPO3_CONF_VARS']['GFX']['processor_effects']

type: bool
Default: false

If enabled, apply blur and sharpening in ImageMagick/GraphicMagick functions

processor_allowUpscaling

$GLOBALS['TYPO3_CONF_VARS']['GFX']['processor_allowUpscaling']

type: bool
Default: true

If set, images can be scaled up if told so (in \TYPO3\CMS\Core\Imaging\GraphicalFunctions )

processor_allowFrameSelection

$GLOBALS['TYPO3_CONF_VARS']['GFX']['processor_allowFrameSelection']

type: bool
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_allowTemporaryMasksAsPng

$GLOBALS['TYPO3_CONF_VARS']['GFX']['processor_allowTemporaryMasksAsPng']

type: bool
Default: false

This should be set if your processor supports using PNGs as masks as this is usually faster.

processor_stripColorProfileByDefault

$GLOBALS['TYPO3_CONF_VARS']['GFX']['processor_stripColorProfileByDefault']

type: bool
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

Changed in version 11.5.35

This string-based configuration option has been superseded by $GLOBALS['TYPO3_CONF_VARS']['GFX']['processor_stripColorProfileParameters'] for security reasons.

$GLOBALS['TYPO3_CONF_VARS']['GFX']['processor_stripColorProfileCommand']

type: string

This option expected a string of command line parameters. The defined parameters had to be shell-escaped beforehand, while the new option processor_stripColorProfileParameters 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:

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

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

processor_stripColorProfileParameters

New in version 11.5.35

$GLOBALS['TYPO3_CONF_VARS']['GFX']['processor_stripColorProfileParameters']

type: array of strings
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 for details.

processor_colorspace

$GLOBALS['TYPO3_CONF_VARS']['GFX']['processor_colorspace']

type: text
Default: RGB

Specifies the colorspace to use. Some ImageMagick versions (like 6.7.0 and above) use the sRGB colorspace, so all images are darker then the original.

Possible Values: CMY, CMYK, Gray, HCL, HSB, HSL, HWB, Lab, LCH, LMS, Log, Luv, OHTA, Rec601Luma, Rec601YCbCr, Rec709Luma, Rec709YCbCr, RGB, sRGB, Transparent, XYZ, YCbCr, YCC, YIQ, YCbCr, YUV

processor_interlace

$GLOBALS['TYPO3_CONF_VARS']['GFX']['processor_interlace']

type: text
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

$GLOBALS['TYPO3_CONF_VARS']['GFX']['jpg_quality']

type: int
Default: 85

Default JPEG generation quality
