Convert DWG to PDF with Coordinates

How to convert DWG to PDF with Coordinates

Aspose.CAD provides the feature to load the AutoCAD DWG file and export it to the PDF format by supplying coordinates. For this, the API provides the CadVportTableObject class. The CadVportTableObject class is used to specify the coordinates for convertion.

The code sample below shows how to convert a DWG file to PDF format by providing coordinates using Aspose.CAD for .NET in C#.

// For complete examples and data files, please go to https://github.com/aspose-cad/Aspose.CAD-for-.NET
// The path to the documents directory.
string MyDir = RunExamples.GetDataDir_DWGDrawings();
string sourceFilePath = MyDir + "visualization_-_conference_room.dwg";
using (CadImage cadImage = (CadImage)Image.Load(sourceFilePath))
{
    CadRasterizationOptions rasterizationOptions = new CadRasterizationOptions();
    rasterizationOptions.Layouts = new string[] { "Model" };
    rasterizationOptions.NoScaling = true;

    // note: preserving some empty borders around part of image is the responsibility of customer
    // top left point of region to draw
    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;

    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;
        }
    }

    // Create an instance of PdfOptions
    Aspose.CAD.ImageOptions.PdfOptions pdfOptions = new Aspose.CAD.ImageOptions.PdfOptions();
    // Set the VectorRasterizationOptions property
    pdfOptions.VectorRasterizationOptions = rasterizationOptions;

    MyDir = MyDir + "ConvertDWGToPDFBySupplyingCoordinates_out.pdf";
    //Export the DWG to PDF
    cadImage.Save(MyDir, pdfOptions);                
}
