Usage examples:

CADNET-839 - Last Author metadata information failed to get extracted

 using (CadImage image = (CadImage) Image.Load(GetFileFromDesktop(fileName1)))

{

    SummaryInfoData summary = image.Header.SummaryInfo;

    Console.WriteLine(summary.Author);

}

CADNET-769 - Support for OBJ format

 using (Aspose.CAD.Image CADDoc = Aspose.CAD.Image.Load(GetFileFromDesktop("example-580-W.obj")))

{

    Aspose.CAD.ImageOptions.CadRasterizationOptions rasterizationOptions =

        new Aspose.CAD.ImageOptions.CadRasterizationOptions();

    rasterizationOptions.PageWidth = CADDoc.Size.Width;

    rasterizationOptions.PageHeight = CADDoc.Size.Height;

    Aspose.CAD.ImageOptions.PdfOptions CADf = new Aspose.CAD.ImageOptions.PdfOptions();

    CADf.VectorRasterizationOptions = rasterizationOptions;

    CADDoc.Save(GetFileFromDesktop("example-580-W_custom.pdf"), CADf);

}

CADNET-23 - Ability to manipulate hyperlinks in AutoCAD drawings

  using (CadImage cadImage = (CadImage) Image.Load(GetFileFromDesktop("Autocad sample.dwg")))

{

    foreach (CadBaseEntity entity in cadImage.Entities)

    {

        if (entity is CadInsertObject)

        {

            CadBlockEntity block = cadImage.BlockEntities[((CadInsertObject) entity).Name];

            if (!string.IsNullOrEmpty(block.XRefPathName.Value))

            {

                block.XRefPathName.Value = "new file reference.dwg";

            }

        }



		if (entity.Hyperlink == "https://products.aspose.com")

        {

            entity.Hyperlink = "https://www.aspose.com";

        }

    }
