Clipping PS with Aspose.Page for .NET

Introduction

Welcome to the comprehensive tutorial on utilizing Aspose.Page for .NET to implement clipping in PostScript (PS) documents. This tutorial will guide you through the process of clipping PS documents using Aspose.Page, a powerful library for working with various document formats in .NET applications.

Prerequisites

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

  • A working knowledge of C# programming language.
  • Aspose.Page for .NET library installed. You can download it here.
  • An integrated development environment (IDE) such as Visual Studio.

Import Namespaces

Begin by importing the necessary namespaces in your C# code:

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

Now, let’s break down the example into multiple steps:

Step 1: Set Document Directory

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

Step 2: Create Output Stream for PostScript Document

// Create output stream for PostScript document
using (Stream outPsStream = new FileStream(dataDir + "Clipping_outPS.ps", FileMode.Create))

Step 3: Create Save Options

// Create save options with default values
PsSaveOptions options = new PsSaveOptions();

Step 4: Create a New 1-Paged PS Document

// Create new 1-paged PS Document
PsDocument document = new PsDocument(outPsStream, options, false);

Step 5: Create Graphics Path from the Rectangle

// Create graphics path from the rectangle
GraphicsPath rectanglePath = new GraphicsPath();
rectanglePath.AddRectangle(new RectangleF(0, 0, 300, 200));

Step 6: Clipping by Shape

// Save graphics state in order to return back to this state after transformation
document.WriteGraphicsSave();

// Displace current graphics state on 100 points to the right and 100 points to the bottom.
document.Translate(100, 100);

// Create graphics path from the circle
GraphicsPath circlePath = new GraphicsPath();
circlePath.AddEllipse(new RectangleF(50, 0, 200, 200));

// Add clipping by circle to the current graphics state
document.Clip(circlePath);

// Set paint in the current graphics state
document.SetPaint(new SolidBrush(Color.Blue));

// Fill the rectangle in the current graphics state (with clipping)
document.Fill(rectanglePath);

// Restore graphics state to the previous (upper) level
document.WriteGraphicsRestore();

Step 7: Displace Upper Level Graphics State

// Displace upper-level graphics state on 100 points to the right and 100 points to the bottom.
document.Translate(100, 100);

Pen pen = new Pen(new SolidBrush(Color.Blue), 2);
pen.DashStyle = DashStyle.Dash;

document.SetStroke(pen);

// Draw the rectangle in the current graphics state (has no clipping) above the clipped rectangle
document.Draw(rectanglePath);

Step 8: Close and Save Document

// Close current page
document.ClosePage();

// Save the document
document.Save();

Now, you have successfully implemented clipping in a PostScript document using Aspose.Page for .NET.

Conclusion

In this tutorial, you learned how to utilize Aspose.Page for .NET to implement clipping in PostScript documents. This powerful library provides a seamless and efficient way to handle various document formats in your .NET applications.
