Convert PostScript to PDF with Aspose.Page for .NET

Introduction

In the ever-evolving landscape of software development, Aspose.Page for .NET stands out as a powerful tool for seamless PostScript to PDF conversion. This tutorial will guide you through the process of using Aspose.Page for .NET to efficiently convert PostScript files to PDF format. Whether you are a seasoned developer or just getting started, this step-by-step guide will help you harness the capabilities of Aspose.Page.

Prerequisites

Before diving into the tutorial, make sure you have the following prerequisites in place:

1. Aspose.Page for .NET Library: Ensure that you have the Aspose.Page for .NET library installed in your development environment. You can download it from here.

2. Development Environment: Set up a working development environment with Visual Studio or any other compatible IDE.

Now that you have the prerequisites covered, let’s explore the steps to convert PostScript to PDF using Aspose.Page for .NET.

Import Namespaces

In the beginning, you need to import the necessary namespaces to access the functionality provided by Aspose.Page for .NET. Place the following code at the beginning of your C# file:

using Aspose.Page.EPS;
using Aspose.Page.EPS.Device;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

Step 1: Initialize Streams

Start by initializing the input and output streams for the PostScript and PDF files. Ensure you replace “Your Document Directory” with the actual path to your document directory.

// The path to the documents directory.
string dataDir = "Your Document Directory";
// Initialize PDF output stream
System.IO.FileStream pdfStream = new System.IO.FileStream(dataDir + "outputPDF_out.pdf", System.IO.FileMode.Create, System.IO.FileAccess.Write);
// Initialize PostScript input stream
System.IO.FileStream psStream = new System.IO.FileStream(dataDir + "input.ps", System.IO.FileMode.Open, System.IO.FileAccess.Read);
PsDocument document = new PsDocument(psStream);

Step 2: Set Conversion Options

To control the conversion process, initialize the options object with necessary parameters. In this example, you can set a flag to suppress minor errors during the conversion.

// If you want to convert Postscript file despite of minor errors set this flag
bool suppressErrors = true;
// Initialize options object with necessary parameters.
PdfSaveOptions options = new PdfSaveOptions(suppressErrors);
// If you want to add a special folder where fonts are stored. Default fonts folder in OS is always included.
options.AdditionalFontsFolders = new string[] { @"{FONT_FOLDER}" };

Step 3: Initialize PDF Device

Create a PDF device to handle the conversion process. You can specify the page size and image format if needed.

// Default page size is 595x842 and it is not mandatory to set it in PdfDevice
Aspose.Page.EPS.Device.PdfDevice device = new Aspose.Page.EPS.Device.PdfDevice(pdfStream);
// But if you need to specify size and image format use the following line
//Aspose.Page.EPS.Device.PdfDevice device = new Aspose.Page.EPS.Device.PdfDevice(pdfStream, new System.Drawing.Size(595, 842));

Step 4: Save the Document

Attempt to save the document using the specified device and options.

try
{
    document.Save(device, options);
}
finally
{
    psStream.Close();
    pdfStream.Close();
}

Step 5: Review Errors

After the conversion, it’s crucial to review any potential errors. If the suppressErrors flag is set, iterate through the exceptions and print error messages.

// Review errors
if (suppressErrors)
{
    foreach (Exception ex in options.Exceptions)
    {
        Console.WriteLine(ex.Message);
    }
}

This comprehensive tutorial guides you through the entire process of using Aspose.Page for .NET to convert PostScript to PDF. Make sure to integrate these steps into your application and explore the vast capabilities of this powerful library.
