DNG validate is a helper plugin that validates DNG files using Adobe's unofficial `dng_validate`, and writes the result to an information field.

The plugin provides both a system task for initializing existing DNGs, as well as listeners for new DNGs (and new version). Note that to validate these DNGs, the asset is downloaded to the appserver and evaluated locally.

The information field can then be used in other plugins, e.g. the [AssetMarker](/celum_extensions/asset_marker) to flag invalid assets.

                        <label lang="de">ungültig</label>
                        <label lang="en">invalid</label>

        </dropdown>
```

#### dngValidate.dngValidityCheckboxInfofieldId

> Type: long, required: no, default: -

Checkbox to set to true if the DNG is valid. This is an alternative to the dropdown.

#### dngValidate.dngOutputTextInfofieldId

> Type: long, required: no, default: -

Textarea field to write the validation log to. Probably not necessary (just enable DEBUG logging), but if you want to show the user what exactly is broken, use this.
