Definindo Propriedades dos Elementos de Estrutura

Para definir propriedades dos elementos de estrutura em um Documento PDF Marcado, Aspose.PDF oferece os métodos CreateSectElement e CreateHeaderElement da interface ITaggedContent.

O seguinte trecho de código mostra como definir propriedades dos elementos de estrutura de um Documento PDF Marcado:

.NET Core 3.1

// For complete examples and data files, visit https://github.com/aspose-pdf/Aspose.PDF-for-.NET
private static void SetProperties()
{
    // The path to the documents directory
    var dataDir = RunExamples.GetDataDir_AsposePdf_WorkingDocuments();

        // Set Title and Language for Document
        taggedContent.SetTitle("Tagged Pdf Document");
        taggedContent.SetLanguage("en-US");

        // Create Structure Elements
        Aspose.Pdf.LogicalStructure.StructureElement rootElement = taggedContent.RootElement;

        Aspose.Pdf.LogicalStructure.SectElement sect = taggedContent.CreateSectElement();
        rootElement.AppendChild(sect);

Para definir um nome de tag personalizada dos elementos de um Documento PDF Marcado, Aspose.PDF oferece o método SetTag da classe StructureElement para elementos. O seguinte trecho de código mostra como definir um nome de tag personalizada:

.NET Core 3.1

Definindo Idioma e Título

Esse recurso é suportado pela versão 19.6 ou superior.

A API Aspose.PDF for .NET também permite que você defina idioma e título para um documento de acordo com a especificação PDF/UA. O idioma pode ser definido tanto para o documento inteiro quanto para seus elementos estruturais separados. O seguinte trecho de código mostra como definir idioma e título em Documento PDF Marcado:
