Export CAD Layouts to Raster Image Formats in Aspose.CAD for .NET

Introduction

Are you looking to efficiently convert CAD layouts to raster image formats using Aspose.CAD for .NET? This step-by-step guide will walk you through the process, providing detailed instructions and code snippets to make the task seamless. Whether you’re a seasoned developer or a newcomer to Aspose.CAD, this tutorial caters to all levels of expertise.

Prerequisites

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

• Aspose.CAD for .NET Library: Ensure that you have the Aspose.CAD library installed. If not, you can download it from the Aspose.CAD website.

• CAD Drawing File: Prepare a CAD drawing file (e.g., conic_pyramid.dxf) that you want to convert to raster image formats.

Import Namespaces

In your .NET project, import the necessary namespaces to leverage Aspose.CAD functionalities. Include the following namespaces at the beginning of your code:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using Aspose.CAD;

Step 1: Load CAD Drawing

string MyDir = "Your Document Directory";
string sourceFilePath = MyDir + "conic_pyramid.dxf";

// Load a CAD drawing in an instance of Image
using (var image = Image.Load(sourceFilePath))
{
    // Your code for loading the CAD drawing goes here
}

Step 2: Create CadRasterizationOptions

// Create an instance of CadRasterizationOptions
var rasterizationOptions = new CadRasterizationOptions();
rasterizationOptions.PageWidth = 500;
rasterizationOptions.PageHeight = 500;

Step 3: Specify Layers

// Add the layer name to the CadRasterizationOptions's layer list
rasterizationOptions.Layers = new string[] { "LayerA" };

Step 4: Create JpegOptions

// Create an instance of JpegOptions (or any ImageOptions for raster formats)
var options = new JpegOptions();
options.VectorRasterizationOptions = rasterizationOptions;

Step 5: Export to Jpeg Format

// Export each layer to Jpeg format
MyDir = MyDir + "CADLayersToRasterImageFormats_out.jpg";
image.Save(MyDir, options);

Additional Step: Convert All Layers

If you want to convert all layers, use the following method:

ConvertAllLayersToRasterImageFormats();

This method iterates over all layers in the CAD drawing, exporting each layer to a separate Jpeg file.

Conclusion

Congratulations! You’ve successfully learned how to export CAD layouts to raster image formats using Aspose.CAD for .NET. This tutorial provides a comprehensive guide for developers seeking efficient and reliable solutions for CAD conversion.
