Methods

Name Description
AddProperties(Func<MetadataProperty, bool>, PropertyValue) Adds known metadata properties satisfying the specified predicate. The operation is recursive so it affects all nested packages as well.
Contains(string) Determines whether the package contains a metadata property with the specified name.
DetectBarcodeTypes() Extracts the types of the barcodes presented in the image.
virtual FindProperties(Func<MetadataProperty, bool>) Finds the metadata properties satisfying the specified predicate. The search is recursive so it affects all nested packages as well.
GetEnumerator() Returns an enumerator that iterates through the collection.
RemoveImageResourcePackage() Removes Photoshop Image Resource metadata package.
virtual RemoveProperties(Func<MetadataProperty, bool>) Removes metadata properties satisfying the specified predicate.
override Sanitize() Removes writable metadata properties from the package. The operation is recursive so it affects all nested packages as well.
SetProperties(Func<MetadataProperty, bool>, PropertyValue) Sets known metadata properties satisfying the specified predicate. The operation is recursive so it affects all nested packages as well. This method is a combination of AddProperties and UpdateProperties. If an existing property satisfies the predicate its value is updated. If there is a known property missing in the package that satisfies the predicate it is added to the package.
UpdateProperties(Func<MetadataProperty, bool>, PropertyValue) Updates known metadata properties satisfying the specified predicate. The operation is recursive so it affects all nested packages as well.
