Add Rectangle to PostScript (PS) with Aspose.Page for .NET

Introduction

If you’re looking to enhance your document creation capabilities in .NET, Aspose.Page provides a powerful solution for handling PostScript documents. In this tutorial, we will guide you through the process of adding rectangles to a PostScript document using Aspose.Page for .NET.

Prerequisites

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

• Aspose.Page for .NET Library: Download and install the Aspose.Page for .NET library from here.

• Development Environment: Make sure you have a .NET development environment set up on your machine.

Import Namespaces

Before you start coding, make sure to import the necessary namespaces to access the required classes and methods:

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 up Your Document Directory

// ExStart:1
// The path to the documents directory.
string dataDir = "Your Document Directory";

In this step, replace “Your Document Directory” with the path where you want to save your PostScript document.

Step 2: Create Output Stream for PostScript Document

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

Here, we create an output stream for the PostScript document and specify the file name (“AddRectangle_outPS.ps”). Adjust the file name and location according to your preferences.

Step 3: Set Save Options and Create PS Document

//Create save options with A4 size
PsSaveOptions options = new PsSaveOptions();

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

Set the save options, specifying the desired page size (A4 in this case). Then, create a new single-paged PostScript document.

Step 4: Add Rectangle and Fill

//Create graphics path from the first rectangle
System.Drawing.Drawing2D.GraphicsPath path = new System.Drawing.Drawing2D.GraphicsPath();
path.AddRectangle(new System.Drawing.RectangleF(250, 100, 150, 100));

//Set paint
document.SetPaint(new System.Drawing.SolidBrush(Color.Orange));

//Fill the rectangle
document.Fill(path);

Here, we create a graphics path representing the first rectangle, set the paint color (in this case, orange), and fill the rectangle.

Step 5: Add Another Rectangle and Stroke

//Create graphics path from the second rectangle
path = new System.Drawing.Drawing2D.GraphicsPath();
path.AddRectangle(new System.Drawing.RectangleF(250, 300, 150, 100));

//Set stroke
document.SetStroke(new System.Drawing.Pen(new System.Drawing.SolidBrush(Color.Red), 3));

//Stroke (outline) the rectangle
document.Draw(path);

Similar to the previous step, we create a graphics path for the second rectangle, set the stroke color (red with a thickness of 3), and outline the rectangle.

Step 6: Close the Page and Save the Document

//Close current page
document.ClosePage();

//Save the document
document.Save();

Finally, close the current page and save the entire document.

Conclusion

Congratulations! You’ve successfully added rectangles to a PostScript document using Aspose.Page for .NET. This tutorial covered the essential steps, from setting up your development environment to saving the final document.
