Text Alignment in accessible/tagged PDFs

Aspose.PDF Product Family

Hi, I’m trying to create a document as an accessible PDF (PDF-UA) . I have a problem with text alignment. How do you get a piece of text center-aligned ?

Thanks!

You can use TextFragment.HorizontalAlignment property as shown below to achieve your requirement. Hope this helps you.

Aspose.Pdf.Document document = new Aspose.Pdf.Document();
Aspose.Pdf.Page page = document.Pages.Add();

Aspose.Pdf.Text.TextFragment text = new Aspose.Pdf.Text.TextFragment("some text");
page.Paragraphs.Add(text);
text.HorizontalAlignment = Aspose.Pdf.HorizontalAlignment.Center;

Thanks for the reply! What you suggest works with general PDFs. But we cannot use TextFragment in accessible or tagged PDF creation.

Could you please ZIP and attach your sample input and expected output PDF files? We will then provide you more information on it.

I cannot copy my work here due to work related constraints. But this example copied from Aspose documentation represent the basic need. In this example, a ParagraphElement is used to add text to the PDF. But I cannot see how it can be aligned the way I want ( right/center/left).

// For complete examples and data files, please go to GitHub - aspose-pdf/Aspose.PDF-for-Java: Aspose.PDF for Java examples, plugins and showcases
// The path to the documents directory.
String path = “pathTodir”;

// Create Pdf Document
Document document = new Document();

// Get Content for work with TaggedPdf
ITaggedContent taggedContent = document.getTaggedContent();

// Set Title and Language for Documnet
taggedContent.setTitle(“Tagged Pdf Document”);
taggedContent.setLanguage(“en-US”);

// Get Root Structure Elements
StructureElement rootElement = taggedContent.getRootElement();

ParagraphElement p = taggedContent.createParagraphElement();
// Set Text to Text Structure Element
p.setText(“Paragraph.”);
rootElement.appendChild(p);

// Save Tagged Pdf Document
document.save(path + “TextStructureElement.pdf”);
