Converting DWG to PDF with Coordinates in C# - Aspose.CAD Tutorial
Introduction
Welcome to this comprehensive tutorial on converting DWG files to PDF with specified coordinates using Aspose.CAD for .NET. Aspose.CAD is a powerful library that allows developers to work with CAD file formats in their .NET applications seamlessly. In this tutorial, we’ll walk you through the process of converting a DWG file to PDF while providing specific coordinates to enhance precision.
Prerequisites
Before we begin, make sure you have the following prerequisites:
Aspose.CAD Library: Download and install the Aspose.CAD library for .NET. You can find the library here.
Development Environment: Ensure that you have a compatible development environment set up, including Visual Studio or any other preferred IDE.
DWG File: Have a DWG file ready for conversion. You can use the provided example file or your custom DWG file.
Import Namespaces
In your C# project, import the necessary namespaces:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using Aspose.CAD;
using Aspose.CAD.FileFormats.Cad;
using Aspose.CAD.FileFormats.Cad.CadParameters;
using Aspose.CAD.FileFormats.Cad.CadTables;
using Aspose.CAD.ImageOptions;
Let’s break down the code into a step-by-step guide for a better understanding:
Step 1: Define the Document Directory
string MyDir = "Your Document Directory";
Step 2: Set the Source DWG File Path
string sourceFilePath = MyDir + "visualization_-_conference_room.dwg";
Step 3: Load DWG File and Configure Rasterization Options
using (CadImage cadImage = (CadImage)Image.Load(sourceFilePath))
{
CadRasterizationOptions rasterizationOptions = new CadRasterizationOptions();
rasterizationOptions.Layouts = new string[] { "Model" };
rasterizationOptions.NoScaling = true;
Step 4: Define Coordinates and Viewport
Point topLeft = new Point(500, 1000);
double width = 3108;
double height = 2489;
CadVportTableObject newView = new CadVportTableObject();
newView.Name = new CadStringParameter();
newView.Name.Init("*Active");
newView.CenterPoint.X = topLeft.X + width / 2f;
newView.CenterPoint.Y = topLeft.Y - height / 2f;
newView.ViewHeight.Value = height;
newView.ViewAspectRatio.Value = width / height;
Step 5: Apply Viewport Settings
for (int i = 0; i < cadImage.ViewPorts.Count; i++)
{
CadVportTableObject currentView = (CadVportTableObject)(cadImage.ViewPorts[i]);
if (cadImage.ViewPorts.Count == 1 || string.Equals(currentView.Name.Value.ToLowerInvariant(), "*active"))
{
cadImage.ViewPorts[i] = newView;
break;
}
}
Step 6: Configure PDF Options and Export
Aspose.CAD.ImageOptions.PdfOptions pdfOptions = new Aspose.CAD.ImageOptions.PdfOptions();
pdfOptions.VectorRasterizationOptions = rasterizationOptions;
MyDir = MyDir + "ConvertDWGToPDFBySupplyingCoordinates_out.pdf";
cadImage.Save(MyDir, pdfOptions);
}
Step 7: Display Success Message
Console.WriteLine("\nThe DWG file exported successfully to PDF.\nFile saved at " + MyDir);
Conclusion
Congratulations! You’ve successfully converted a DWG file to PDF with specified coordinates using Aspose.CAD for .NET. This tutorial covered essential steps and provided a clear guide for developers.
