Add support for custom PDF metadata

This improvement allows users to apply redactions to custom XML metadata within PDF files, including metadata of the embedded image resources.

Public API changes

Method getCategory(), returning ID of the embedded resource, has been added to MetadataItem class.


The following example demonstrates how to remove strings like “/first.last” (e.g. user name in source file paths) from the embedded images metadata of a PDF file.


            try (Redactor redactor = new Redactor("FileWithEmbeddedImages.pdf"))
                RedactorChangeLog result = redactor.apply(new MetadataSearchRedaction(@"/([^\./]+\.[^/]+)", "/redacted"));
                if (result.getStatus() != RedactionStatus.Failed)
           SaveOptions(false, "Redacted"));
