Add Text with Unicode String to PostScript (PS) with Aspose.Page

Introduction

In the realm of document manipulation, Aspose.Page for .NET stands out as a robust library that empowers developers to create, edit, and convert various document formats. One of its powerful features is the ability to add text using Unicode strings to PostScript (PS) files. In this tutorial, we’ll explore a step-by-step guide on accomplishing this task, providing a seamless experience for developers working with Aspose.Page.

Prerequisites

Before diving into the tutorial, ensure you have the following prerequisites:

• A working knowledge of C# programming language.
• Aspose.Page for .NET library installed. You can download it from the Aspose.Page for .NET documentation.
• A development environment set up with necessary configurations.

Import Namespaces

In your C# code, import the required namespaces for using Aspose.Page for .NET functionalities:

using Aspose.Page;
using Aspose.Page.EPS;
using Aspose.Page.EPS.Device;
using Aspose.Page.Font;
using System.Drawing;
using System.Drawing.Drawing2D;
using System.IO;

Step 1: Set Up Document Directory and Fonts Folder

// The path to the documents directory.
string dataDir = "Your Document Directory";
string FONTS_FOLDER = "Your Fonts Directory";

Step 2: Create Output Stream for PostScript Document

using (Stream outPsStream = new FileStream(dataDir + "AddTextUsingUnocodeString_outPS.ps", FileMode.Create))
{
    // Create save options with A4 size
    PsSaveOptions options = new PsSaveOptions();
    options.AdditionalFontsFolders = new string[] { FONTS_FOLDER };
    // ... (Additional options can be set here)
    
    // Create new 1-paged PS Document
    PsDocument document = new PsDocument(outPsStream, options, false);
    
    // ... (Further steps will be explained below)
    
    // Save the document
    document.Save();
}

Step 3: Add Unicode Text with Custom Font

string str = "試してみます.";  // Unicode text
int fontSize = 48;

// Using custom font for filling text
DrFont drFont = ExternalFontCache.FetchDrFont("Arial Unicode MS", fontSize, FontStyle.Regular);
document.FillText(str, drFont, 50, 200);
document.FillText(str, drFont, 50, 250, new SolidBrush(Color.Blue));

Step 4: Close the Current Page

document.ClosePage();

Step 5: Finalize and Save the Document

document.Save();

Conclusion

In this tutorial, we’ve walked through the process of adding Unicode text to a PostScript document using Aspose.Page for .NET. Leveraging its powerful capabilities, developers can enhance their document manipulation workflows, ensuring flexibility and precision.
