Position of the exported region

Aspose.CAD Product Family
1

Hello there,
I am trying to convert a DXF to PDF with AsposeCAD for .NET, ver 21.4.0. I want to convert a layout to PDF, but my issue is that the exported region is not centered in the PDF created with Aspose.
How can I set the position of the exported region?

Here is the zip archive with the DXF, the PDF from Aspose, and a desired PDF.

Can you please share the sample code that you have used on your end so that I may investigate that on my end to help you further.

Hello, here is my code

using (CadImage image = (CadImage)Image.Load(sourceFilePath))
			{
				CadRasterizationOptions rasterizationOptions = new CadRasterizationOptions();
				rasterizationOptions.UnitType = UnitType.Millimeter;
				
				//A3
				rasterizationOptions.PageWidth = 420;
				rasterizationOptions.PageHeight = 297;

				rasterizationOptions.Layouts = new string[] {"Layout1" };

				rasterizationOptions.DrawType = CadDrawTypeMode.UseObjectColor;

				PdfOptions pdfOptions = new PdfOptions();

				pdfOptions.VectorRasterizationOptions = rasterizationOptions;

				string fileName = Path.GetFileName(sourceFilePath);
				string outputDir = Path.GetDirectoryName(sourceFilePath);
				string outputFileName = fileName.Replace(".dxf", ".pdf");
				string savePDFfilePath = outputDir + @"\" + outputFileName;
				image.Save(savePDFfilePath, pdfOptions);
			}

Please try using following sample code on your end.

    public static void TestPDFExport()
    {
        String sourceFilePath = @"/Users/mudassirkhan/Downloads/forum_request/";
        using (CadImage image = (CadImage)Image.Load(sourceFilePath+ "A3_PAPER.dxf"))
        {
            CadRasterizationOptions rasterizationOptions = new CadRasterizationOptions();
            rasterizationOptions.UnitType = UnitType.Millimeter;

            //A3
            rasterizationOptions.PageWidth = 1600;
            rasterizationOptions.PageHeight = 1600;

            rasterizationOptions.Layouts = new string[] { "Layout1" };

            rasterizationOptions.DrawType = CadDrawTypeMode.UseObjectColor;

            PdfOptions pdfOptions = new PdfOptions();

            pdfOptions.VectorRasterizationOptions = rasterizationOptions;

            string fileName = Path.GetFileName(sourceFilePath);
            string outputDir = Path.GetDirectoryName(sourceFilePath);
            string outputFileName = "2.pdf";
            string savePDFfilePath = outputDir + @"/" + outputFileName;
            image.Save(savePDFfilePath, pdfOptions);
        }


    }

Thanks for your reply.

In your code, the only difference is on page width and height, that are bigger than the ones on my end.

Is it possible to export a PDF with the same width and height of the layout of the DXF?
Or, at least, is it possible to export a PDF with the same aspect ratio of the layout of the DXF?

You may try that on your end but you still need to have a considerable size to avoid truncating of information in output.
