CadImage header data is not saved

Aspose.CAD Product Family

Hello,

I try to save some data in CadImage header. CustomProperties should allow me to do this, but when I try to read the header, it turns out that the CustomProperties are empty. My testing code is shown below. Screenshoot added. Maybe I am doing something wrong? I would be grateful for any help.

using (Image img = Image.Load("C://input.dwg"))
        {
            CadImage cad = img as CadImage;

            cad.Header.CustomProperties.Add("test", "testingValue");

            cad.Save("C://save.dxf", new DxfOptions()
            {
                VectorRasterizationOptions = new CadRasterizationOptions()
                {
                    DrawType = CadDrawTypeMode.UseObjectColor,
                    PageHeight = 1600,
                    PageWidth = 1600
                }
            });
        }

        using (Image img = Image.Load("C://save.dxf"))
        {
            CadImage cad = img as CadImage;

            string value = string.Empty;

            Console.WriteLine(cad.Header.CustomProperties.Count);
            if(cad.Header.CustomProperties.TryGetValue("test", out value))
            {
                Console.WriteLine(value);
            }
        }

Can you please share the source DWG/DXF along with generated output. We will investigate the issue on our end to help you out.

Of course, thank you for reply. Files are attached. I also found out one interesting thing. If I save my file without any options, just using this construction: cad.Save("C://save.dxf"); in output I’ll have damaged file that cannot be opened with AutoCAD or any other CAD viewing tool. But this corrupted file contains all my custom headers. Otherwise, by saving file with DxfOptions (as shown in my first message) I have correct output .dxf file that is readeable by AutoCAD. But the correct file does not containt any custom headers. The best scenario would be receiving readable file with all my headers inside :slight_smile:

Hello,

I was notified that issue CADNET-1362 has been fixed, but using newest version (21.5) of Aspose.CAD library I still cannot run my testing example. Same code as above:

using (Image img = Image.Load("C://input.dwg"))
{
     CadImage cad = img as CadImage;
     cad.Header.CustomProperties.Add("test", "testingValue");
     cad.Save("C://save.dxf", new DxfOptions()
     {
         VectorRasterizationOptions = new CadRasterizationOptions()
         {
             DrawType = CadDrawTypeMode.UseObjectColor,
             PageHeight = 1600,
             PageWidth = 1600
         }
     });
}

using (Image img = Image.Load("C://save.dxf"))
{
    CadImage cad = img as CadImage;
    string value = string.Empty;

    Console.WriteLine(cad.Header.CustomProperties.Count);
    if (cad.Header.CustomProperties.TryGetValue("test", out value))
    {
        Console.WriteLine(value);
    }
}

Maybe I am missing some options params?
