Create PDF A1 With Aspose Pdf

In this step-by-step guide, we will explain how to use Aspose.PDF for .NET to create a PDF A1 document. We will provide you with the necessary C# source code and instructions to accomplish this task.

Step 1: Define variables and import namespaces

First, define the variable dataDir to represent the directory where your documents are stored. This will be used to specify the output file path.

string dataDir = "YOUR DOCUMENT DIRECTORY";

Next, create a new instance of the Document class from Aspose.PDF.

Aspose.Pdf.Document pdf1 = new Aspose.Pdf.Document();

Step 2: Add content to the PDF

In this step, we will add a page to the PDF document and insert a text fragment containing the text “Hello World!”.

pdf1.Pages.Add().Paragraphs.Add(new TextFragment("Hello World!"));

Step 3: Save the PDF to a memory stream

To convert the PDF to PDF/A1 format, we need to save it to a memory stream.

MemoryStream ms = new MemoryStream();
pdf1.Save(ms);

Step 4: Convert the PDF to PDF/A1 format

Now, we will convert the PDF to PDF/A1 format using the Convert method of the Document class. We pass a new memory stream as the output stream and specify the PdfFormat.PDF_A_1A format.

pdf1.Convert(new MemoryStream(), PdfFormat.PDF_A_1A, ConvertErrorAction.Delete);

Step 5: Save the converted PDF

Finally, save the converted PDF to the specified directory.

pdf1.Save(dataDir + "CreatePdfA1_out.pdf");

Example source code for Create PDF A1 using Aspose.PDF for .NET

// The path to the documents directory.
string dataDir = "YOUR DOCUMENT DIRECTORY";

Aspose.Pdf.Document pdf1 = new Aspose.Pdf.Document();
// Add a page into the pdf document

MemoryStream ms = new MemoryStream();
// Save the document
pdf1.Save(ms);
pdf1.Convert(new MemoryStream(), PdfFormat.PDF_A_1A, ConvertErrorAction.Delete);
pdf1.Save(dataDir + "CreatePdfA1_out.pdf");

By following these steps and using the provided source code, you can create a PDF A1 document using Aspose.PDF for .NET.

Remember to adjust the “YOUR DOCUMENT DIRECTORY” with the appropriate directory path where you want to save the output file.
