LegacyThumbnailMigrationHelper deprecated
class LegacyThumbnailMigrationHelper (View source)
deprecated
Service to migrate legacy format thumbnails, to avoid regenerating them on demand.
Related to SilverStripe\AssetAdmin\Helper\ImageThumbnailHelper, which proactively generates the (new) thumbnails required for asset-admin previews.
Migrates thumbnails regardless whether their original file still exists, since they might still be hot-linked. Relies on the legacy file format redirections introduced in 4.3.3 and 4.4.0 for those hot-links to continue resolving.
Example file format:
Before (3.x): assets/my-folder/_resampled/PadWzYwLDYwLCJGRkZGRkYiLDBd/FillWzYwLDMwXQ/my-image.jpg
After (4.x): assets/my-folder/0ec62bd1c4/my-image__PadWzYwLDYwLCJGRkZGRkYiLDBd_CropHeightWzMwXQ.jpg
Limitations:
- Does not migrate legacy thumbnails where the original file or folder has been renamed since an earlier 4.x migration run
- Does not filter out unused CMS thumbnails (they're using a new size now)
- Does not move legacy thumbnails to the protected store if the original file has been unpublished or protected since an earlier 4.x migration run

Methods
An implementation of the factory method, allows you to create an instance of a class
Creates a class instance by the "singleton" design pattern.
Get a configuration accessor for this class. Short hand for Config::inst()->get($this->class, .....).
Gets the uninherited value for the given config option

static Injectable
create(mixed ...$args)
An implementation of the factory method, allows you to create an instance of a class
This method will defer class substitution to the Injector API, which can be customised via the Config API to declare substitution classes.
This can be called in one of two ways - either calling via the class directly, or calling on Object and passing the class name as the first parameter. The following are equivalent: $list = DataList::create(SiteTree::class); $list = SiteTree::get();
static Injectable
singleton(string $class = null)
Creates a class instance by the "singleton" design pattern.
It will always return the same instance for this class, which can be used for performance reasons and as a simple way to access instance methods which don't rely on instance data (e.g. the custom SilverStripe static handling).

config()
Get a configuration accessor for this class. Short hand for Config::inst()->get($this->class, .....).
