Document Reflow with XLIFF

Content reflow is designed to eliminate formatting headaches when translating or updating PDFs. Instead of manually copy-pasting content and fixing layouts, it extracts text into XLIFF format, an industry-standard translation file that maintains

Fonts
Layouts
Tables

No more manual reformatting.

The format provides seamless integration with translation tools and enterprise scalability.

Trial mode page limit

When in trial mode, output is limited to 10 pages. Once licensed, there is no page limit.

How Does Content Reflow Work for my translation needs?

Unlike traditional translation workflows that require manually extracting and reinserting text, XLIFF Reflow automates this process by converting text into XLIFF format, an industry-standard file type for translation workflows.

Important

The XLIFF translation feature requires PDFs with extractable text; scanned or image‑only PDFs result in malformed XLIFF files and missing content. If required glyphs are missing from an embedded font, the system applies font substitution, which may affect visual output but does not fail the operation.

Step 1

Extract Text into XLIFF Format and save the fielded PDF

1// Open a PDF to translate.
2PDFDoc doc(input_path + "document.pdf");
3
4// Optionally, subset the pages to process
5// This PDF only has a single page, but you can specify a subset of pages like this
6// options.SetPages("-2,5-6,9,11-");
7
8// Optionally, set the XLIFF exported version, default is 1.2
9// options.SetXLIFFVersion(TransPDFOptions::e_xliff_version_2);
10
11// Extract the xlf to file and field the PDF for translation
12TransPDF::ExtractXLIFF(doc, output_path + "output.xlf", pageSet);
13
14// Save the fielded PDF
15doc.Save(output_path + "document-fielded.pdf", SDFDoc::e_linearized);

1// Open a PDF to translate.
2FileStream istm = new FileStream(input_path + "document.pdf", FileMode.Open, FileAccess.Read);
3
4using (PDFDoc doc = new PDFDoc(istm))
5{
6    // Optionally, subset the pages to process
7		// This PDF only has a single page, but you can specify a subset of pages like this
8		// options.SetPages("-2,5-6,9,11-");
9
10		// Optionally, set the XLIFF exported version, default is 1.2
11		// options.SetXLIFFVersion(TransPDFOptions.XLIFFVersion.e_xliff_version_2);
12
13    // Extract the xlf to file and field the PDF for translation
14    TransPDF.ExtractXLIFF(doc, output_path + "output.xlf", pageSet);
15    
16    // Save the fielded PDF
17    doc.Save(output_path + "document-fielded.pdf", SDFDoc.SaveOptions.e_linearized);
18}

1// Open a PDF document to translate
2PDFDoc doc = new PDFDoc(input_path + "document.pdf")
3
4// Optionally, subset the pages to process
5// This PDF only has a single page, but you can specify a subset of pages like this
6// options.setPages("-2,5-6,9,11-");
7
8// Optionally, set the XLIFF exported version, default is 1.2
9// options.setXLIFFVersion(TransPDFOptions.XLIFFVersion.e_xliff_version_2);
10
11// Extract the xlf to file and field the PDF for translation
12TransPDF.extractXLIFF(doc, output_path + "original.xlf", options);
13
14// Save the fielded PDF
15doc.save(output_path + "document-fielded.pdf", SDFDoc.SaveMode.LINEARIZED, null);

Step 2

Do your translation. Here you would send the XLIFF file to your preferred computer assisted software, online or running locally.

Step 3

Reflow Translated Text Back into the fielded PDF

1// Open the fielded PDF generated by ExtractXLIFF
2PDFDoc doc(output_path + "document-fielded.pdf");
3
4// Perform the translation using the pre-prepared translated xliff
5TransPDF::ApplyXLIFF(doc, input_path + "translated_output_(en_to_fr).xlf", options);
6
7// Save the translated PDF
8doc.Save(output_path + "document-fr.pdf", SDFDoc::e_linearized);

1// Open the fielded PDF generated by ExtractXLIFF
2FileStream istm = new FileStream(output_path + "document-fielded.pdf", FileMode.Open, FileAccess.Read);
3
4using (PDFDoc doc = new PDFDoc(istm))
5{
6  // Perform the translation using the pre-prepared translated xliff
7  TransPDF.ApplyXLIFF(doc, input_path + "translated_output_(en_to_fr).xlf", options);
8
9  // Save the translated PDF
10  doc.Save(output_path + "document-fr.pdf", SDFDoc.SaveOptions.e_linearized);
11  doc.Close();
12}

1// Open the fielded PDF generated by ExtractXLIFF
2PDFDoc doc = new PDFDoc(output_path + "document-fielded.pdf")
3
4// Perform the translation using the pre-prepared translated xliff
5TransPDF.applyXLIFF(doc, input_path + "translated_output_(en_to_fr).xlf", options);
6
7// Save the translated PDF
8doc.save(output_path + "document-fr.pdf", SDFDoc.SaveMode.LINEARIZED, null);
9doc.close();
