Is it possible to print all the views from a 3D PDF viewer, using Aspose.PDF or another Aspose product?

Cause

Currently, Aspose.PDF does not provide a direct method to print all views from a 3D PDF viewer. However, you can implement custom printing functionality using the PdfViewer class, which allows you to handle printing events and customize the print job.

Solution

To print a 3D PDF, you can set up a custom print handler using the CustomPrint event of the PdfViewer class. This allows you to define how the printing should be executed, including specifying the printer settings and handling the print job.

Code

Here’s a basic example of how to set up a custom print handler for a PDF document:

using Aspose.Pdf.Facades;
using System.Diagnostics;
using System.Text;

public void Print3DPDF(string pdfPath)
{
    var viewer = new PdfViewer();
    viewer.BindPdf(pdfPath);

    // Set a custom printing handler
    viewer.CustomPrint += ViewerOnCustomPrint;

    var ps = new PrinterSettings
    {
        PrinterName = "YourPrinterName"
    };
    var pgs = ps.DefaultPageSettings;
    pgs.PaperSize = PaperSizes.A4;

    // Print the document
    viewer.PrintDocumentWithSettings(pgs, ps);
    viewer.Close();
}

private void ViewerOnCustomPrint(object sender, CustomPrintEventArgs e)
{
    var command = new StringBuilder("lp ");
    command.AppendFormat("-d {0} ", e.PrinterSettings.PrinterName);
    
    // Additional settings can be added here
    command.AppendFormat("-- {0} ", e.FileName);

    var psi = new ProcessStartInfo
    {
        FileName = "/bin/bash",
        Arguments = string.Format("-c \"{0}\"", command.ToString()),
        RedirectStandardOutput = true,
        UseShellExecute = false,
        CreateNoWindow = true
    };

    using (var process = Process.Start(psi))
    {
        process.WaitForExit();
    }
}

Next Steps

  1. Replace "YourPrinterName" with the actual name of your printer.
  2. Customize the ViewerOnCustomPrint method to include any additional print settings you may need.
  3. Test the implementation to ensure it meets your requirements for printing 3D views.
