Convert PDF Documents to Markdown Files

With the Spire.PDF for .NET library, developers can easily load any PDF file using the PdfDocument.LoadFromFile(string filename) method and then save the document in the desired format by calling the PdfDocument.SaveToFile(string filename, FileFormat fileFormat) method. To convert a PDF to Markdown format, simply specify the FileFormat.Markdown enumeration as a parameter when invoking the method.

The detailed steps for converting PDF documents to Markdown files are as follows:

• Create an instance of PdfDocument class.
• Load a PDF document using PdfDocument.LoadFromFile(string filename) method.
• Convert the document to a Markdown file using PdfDocument.SaveToFile(string filename, FileFormat.Markdown) method.

using Spire.Pdf;

namespace PDFToMarkdown
{
    class Program
    {
        static void Main(string[] args)
        {
            // Create an instance of PdfDocument class
            PdfDocument pdf = new PdfDocument();

            // Load a PDF document
            pdf.LoadFromFile("Sample.pdf");

            // Convert the document to Markdown file
            pdf.SaveToFile("output/PDFToMarkdown.md", FileFormat.Markdown);

            // Release resources
            pdf.Close();
        }
    }
}

Convert PDF to Markdown by Streams

In addition to directly reading files for manipulation, Spire.PDF for .NET also supports loading a PDF document from a stream using PdfDocument.LoadFromStream() method and converting it to a Markdown file stream using PdfDocument.SaveToStream() method. Using streams reduces memory usage, supports large files, enables real-time data transfer, and simplifies data exchange with other systems.

The detailed steps for converting PDF documents to Markdown files by streams are as follows:

• Create a Stream object of PDF documents by downloading from the web or reading from a file.
• Load the PDF document from the stream using PdfDocument.LoadFromStream(Stream stream) method.
• Create another Stream object to store the converted Markdown file.
• Convert the PDF document to a Markdown file stream using PdfDocument.SaveToStream(Stream stream, FileFormat.Markdown) method.

using Spire.Pdf;
using System.IO;
using System.Net.Http;

namespace PDFToMarkdownByStream
{
    class Program
    {
        static async Task Main(string[] args)
        {
            // Create an instance of PdfDocument class
            PdfDocument pdf = new PdfDocument();

            // Download a PDF document from a url as bytes
            using (HttpClient client = new HttpClient())
            {
                byte[] pdfBytes = await client.GetByteArrayAsync("http://example.com/Sample.pdf");

                // Create a MemoryStream using the bytes
                using (MemoryStream inputStream = new MemoryStream(pdfBytes))
                {
                    // Load the PDF document from the stream
                    pdf.LoadFromStream(inputStream);

                    // Create another MemoryStream object to store the Markdown file
                    using (MemoryStream outputStream = new MemoryStream())
                    {
                        // Convert the PDF document to a Markdown file stream
                        pdf.SaveToStream(outputStream, FileFormat.Markdown);
                        outputStream.Position = 0; // Reset the position of the stream for subsequent reads

                        // Upload the result stream or write it to a file
                        await client.PostAsync("http://example.com/upload", new StreamContent(outputStream));
                        File.WriteAllBytes("output.md", outputStream.ToArray());
                    }
                }
            }

            // Release resources
            pdf.Close();
        }
    }

PostScript was developed by Adobe Systems in the 1980s as a way of turning digital graphics or text files into a fixed format ready for printing. With the passage time, although the PostScript (PS) file format is no longer as popular as it once was, now it is still supported by most printers. In this article, you will learn how to how to programmatically convert a PDF file to a PostScript (PS) file using Spire.PDF for .NET.

Install Spire.PDF for .NET

To begin with, you need to add the DLL files included in the Spire.PDF for.NET package as references in your .NET project. The DLL files can be either downloaded from this link or installed via NuGet.

PM> Install-Package Spire.PDF 

Convert PDF to PostScript in C# and VB.NET

Converting PDF to PS can improve the quality of the printed output. With Spire.PDF for .NET, you can complete the conversion with only three lines of code. The following are the detailed steps.

• Create a PdfDocument instance.
• Load a sample PDF file using PdfDocument.LoadFromFile() method.
• Save the PDF file as a PS file using PdfDocument.SaveToFile(string filename, FileFormat.POSTSCRIPT) method.

using Spire.Pdf;

namespace PDFtoPS
{
    class Program
    {
        static void Main(string[] args)
        {
            //Create a PdfDocument instance
            PdfDocument document = new PdfDocument();

            //Load a sample PDF file
            document.LoadFromFile("Test.pdf");

            //Save the PDF file as a PS file
            document.SaveToFile("toPostScript.ps", FileFormat.POSTSCRIPT);
        }
    }
}

Imports Spire.PDF

Namespace PDFtoPS
    Class Program
        Private Shared Sub Main(ByVal args() As String)

            'Create a PdfDocument instance
            Dim document As PdfDocument = New PdfDocument

            'Load a sample PDF file
            document.LoadFromFile("Test.pdf")

            'Save the PDF file as a PS file
            document.SaveToFile("toPostScript.ps", FileFormat.POSTSCRIPT)
        End Sub
    End Class
End Namespace

A PCL file is a Printer Command Language document. Printer Command Language is a page description language developed by HP as a printer protocol and has been widely supported in many printers now. Start from version 5.2.3, Spire.PDF supports converting PDF file to PCL format. There are six major levels of PCL, the PCL here refers to PCL 6 (PCL 6 Enhanced or PCL XL).

Example code

using Spire.Pdf;

namespace PDFtoPCL
{
    class Program
    {
        static void Main(string[] args)
        {
            //Create a PdfDocument instance
            PdfDocument pdf = new PdfDocument();
            //Load the PDF file
            pdf.LoadFromFile("Input.pdf");
            //Save to PCL format
            pdf.SaveToFile("ToPCL.pcl", FileFormat.PCL);
        }
    }
}

Imports Spire.Pdf

Namespace PDFtoPCL
	Class Program
		Private Shared Sub Main(args As String())
			Dim pdf As PdfDocument = New PdfDocument()
    pdf.LoadFromFile("Input.pdf")
    pdf.SaveToFile("ToPCL.pcl", FileFormat.PCL)
		End Sub
	End Class
End Namespace

This article we will demonstrate how to convert the PDF pages to HTML, Word, SVG, XPS, PDF and save them to stream by calling the method PdfDocument.SaveToStream() offered by Spire.PDF. And starts from Spire.PDF version 4.3, it newly supports to convert the defined range of PDF pages and save them to stream.

Save the PDF to stream

Step 1: Create a new PdfDocument instance and load the sample document from file.

PdfDocument pdf = new PdfDocument();
pdf.LoadFromFile("Sample.pdf");

Step 2: Save the document to stream.

MemoryStream ms=new MemoryStream ();
pdf.SaveToStream(ms);

Save the PDF to stream and defined the file format to HTML, Word, SVG, XPS and PDF

Step 1: Create a new PdfDocument instance and load the sample document from file.

PdfDocument pdf = new PdfDocument();
pdf.LoadFromFile("Sample.pdf");

Step 2: Save the document to stream and use FileFormat format to define the format.

MemoryStream ms=new MemoryStream ();
pdf.SaveToStream(ms, FileFormat.HTML);

Convert the defined range of PDF pages to HTML, word, SVG, XPS and save them to stream

Step 1: Create a new PdfDocument instance and load the sample document from file.

PdfDocument pdf = new PdfDocument();
pdf.LoadFromFile("Sample.pdf"); 

Step 2: Only save some PDF pages to stream by using pdf.SaveToStream(int startIndex, int endIndex, FileFormat format) method; and FileFormat.PDF is not supported.

pdf.SaveToStream(1, 2, FileFormat.SVG);

Full codes of save PDF to stream:

using Spire.Pdf;
using System.IO;


namespace SavePDFToStream
{
    class Program
    {
        static void Main(string[] args)
        {
            PdfDocument pdf = new PdfDocument();

            pdf.LoadFromFile("Sample.pdf");

            MemoryStream ms = new MemoryStream();
            pdf.SaveToStream(ms);
            pdf.SaveToStream(ms, FileFormat.HTML);

            pdf.SaveToStream(1, 2, FileFormat.SVG);
        }
    }
}
