How to add cropVariants to an image field in TYPO3

Question

I can override the cropVaraints for an image field in TCA like this:

'columnsOverrides' => [
    'image' => [
        'label' => 'LLL:EXT:myext/Resources/Private/Language/locallang_be.xlf:general.field.image',
        'config' => [
            'overrideChildTca' => [
                'columns' => [
                    'crop' => [
                        'config' => [
                            'cropVariants' => [
                                'default' => [
                                    'title' => 'LLL:EXT:myext/Resources/Private/Language/locallang_be.xlf:wizard.banner.title',
                                    'allowedAspectRatios' => [
                                        '2:1' => [
                                            'title' => 'LLL:EXT:myext/Resources/Private/Language/locallang_be.xlf:field.banner.image-crop.ratio',
                                            'value' => 2 / 1
                                        ],
                                    ],
                                ],
                            ],
                        ],
                    ],
                ],
            ],
        ],
    ],
],

I tryed to adabt this to flexform - but without any success. So what I need is something like this (but working :-) )

<foreign_selector_fieldTcaOverride type="array">
    <config>
        <appearance>
            <elementBrowserType>file</elementBrowserType>
            <elementBrowserAllowed>jpg,png</elementBrowserAllowed>
        </appearance>
        <overrideChildTca>
            <columns>
                <crop>
                    <config>
                        <cropVariants>
                            <default>
                                <title>Blubber</title>
                                <allowedAspectRatios>
                                    <test>
                                        <title>2:1</title>
                                        <value>2 / 1</value>
                                    </test>
                                </allowedAspectRatios>
                            </default>
                        </cropVariants>
                    </config>
                </crop>
            </columns>
        </overrideChildTca>
    </config>
</foreign_selector_fieldTcaOverride>

Does anybody did that before?

If it is not possible, maybe I can get arround the flexform? I currently have a gridelement with an Image field.

[UPDATE] As @fnagel pointed out it should be possible with overriding the default, so I tried to put the following into my Overrides/sys_file_reference.php - but it has no effect - I could even not find that default definition in TCA-Inspector...

$GLOBALS['TCA']['sys_file_reference']['columns']['crop']['config‌']['cropVariants‌​']['default'] = [
    'title' => 'LLL:EXT:al_template/Resources/Private/Language/locallang_be.xlf:wizard.gallery.title',
    'allowedAspectRatios' => [
        'NaN' => [
            'title' => 'LLL:EXT:al_template/Resources/Private/Language/locallang_be.xlf:field.gallery.image-crop.ratio',
            'value' => 0.0
        ],
    ],
];

writing ot as has also no effect...

 \TYPO3\CMS\Core\Utility\ArrayUtility::mergeRecursiveWithOverrule(
    $GLOBALS['TCA']['sys_file_reference'],
    [
        'columns' =>[
            'crop' => [
                'config‌' => [
                    'cropVariants‌​' => [
                        'default'=> [
                            'title' => 'LLL:EXT:al_template/Resources/Private/Language/locallang_be.xlf:wizard.gallery.title',
                            'allowedAspectRatios' => [
                                'NaN' => [
                                    'title' => 'LLL:EXT:al_template/Resources/Private/Language/locallang_be.xlf:field.gallery.image-crop.ratio',
                                    'value' => 0.0
                                ],
                            ],
                        ],
                    ],
                ],
            ],
        ],
    ]
);

Anybody with a successfull setup for that?

Answer 1

To allow image manipulation in a flexform you have to enable it via overrideChildTca property.

Example flexform:

        <background_image type="array">
            <TCEforms>
                <label>LLL:EXT:myext/Resources/Private/Language/Backend.xlf:background_image
                </label>
                <config>
                    <type>inline</type>
                    <minitems>1</minitems>
                    <maxitems>1</maxitems>
                    <appearance type="array">

                </config>
            </TCEforms>
        </background_image>

After enable it, you can define custom ratio via TsConfig:

TCEFORM.sys_file_reference.crop.config.cropVariants {
  default {
    title = LLL:EXT:lang/Resources/Private/Language/locallang_wizards.xlf:imwizard.ratio.free
    selectedRatio = NaN
    allowedAspectRatios {
      NaN {
        title = free
        value = 0.0
      }
    }
  }
}

Works on TYPO3 8 LTS

Answer 2

Not possible afaik. You will need to set an overall default and adjust it for all other elements using TCA.
