Embed Standard Type 1Fonts In PDF File

This tutorial will guide you through the process of embedding standard Type 1 fonts in PDF file using Aspose.PDF for .NET. The provided C# source code demonstrates the necessary steps.

Requirements

Before you begin, ensure that you have the following:

  • Visual Studio or any other C# compiler installed on your machine.
  • Aspose.PDF for .NET library. You can download it from the official Aspose website or use a package manager like NuGet to install it.

Step 1: Set up the project

  1. Create a new C# project in your preferred development environment.
  2. Add a reference to the Aspose.PDF for .NET library.

Step 2: Import required namespaces

In the code file where you want to embed standard Type 1 fonts, add the following using directive at the top of the file:

using Aspose.Pdf;

Step 3: Set the document directory

In the code, locate the line that says string dataDir = "YOUR DOCUMENT DIRECTORY"; and replace "YOUR DOCUMENT DIRECTORY" with the path to the directory where your documents are stored.

Step 4: Load the existing PDF document

Load an existing PDF document using the Document constructor and passing the path to the input PDF file.

Document pdfDocument = new Document(dataDir + "input.pdf");

Step 5: Set the EmbedStandardFonts property

Set the EmbedStandardFonts property of the document to true in order to enable embedding standard Type 1 fonts.

pdfDocument.EmbedStandardFonts = true;

Step 6: Embed fonts in each page

Loop through each page of the PDF document and check if the fonts are already embedded. If not, set the IsEmbedded property to true to embed the font.

foreach(Page page in pdfDocument.Pages)
{
     if (page.Resources.Fonts != null)
     {
         foreach(Aspose.Pdf.Text.Font pageFont in page.Resources.Fonts)
         {
             if (!pageFont.IsEmbedded)
             {
                 pageFont.IsEmbedded = true;
             }
         }
     }
}

Step 7: Save the updated PDF document

Save the updated PDF document using the Save method of the Document object, specifying the output file path.

pdfDocument.Save(dataDir + "EmbeddedFonts-updated_out.pdf");

Sample source code for Embed Standard Type 1Fonts using Aspose.PDF for .NET

// The path to the documents directory.
string dataDir = "YOUR DOCUMENT DIRECTORY";
// Load an existing PDF Document
Document pdfDocument = new Document(dataDir + "input.pdf");
// Set EmbedStandardFonts property of document
pdfDocument.EmbedStandardFonts = true;
foreach (Aspose.Pdf.Page page in pdfDocument.Pages)
{
	if (page.Resources.Fonts != null)
	{
		foreach (Aspose.Pdf.Text.Font pageFont in page.Resources.Fonts)
		{
			// Check if font is already embedded
			if (!pageFont.IsEmbedded)
			{
				pageFont.IsEmbedded = true;
			}
		}
	}
}
pdfDocument.Save(dataDir + "EmbeddedFonts-updated_out.pdf");

Conclusion

You have successfully embedded standard Type 1 fonts in a PDF document using Aspose.PDF for .NET. The updated PDF file with embedded fonts has been saved at the specified output file path.
