How to move drawing down to add title

Issue: How to move drawing down to add title (CADNET-980).

Tips: To do this, create a CadText object with parameters, add this block to the drawing, then update the drawing with the new dimensions with UpdateSize, add a polyline that is a frame around the drawing, add the polyline to BlockEntities["*Model_Space"] and update again with UpdateSize.

Example:

using (CadImage cadImage = (CadImage)Image.Load(GetPath(fileName)))
{
    CadText text = new CadText();
    text.DefaultValue = "CAD Drawing";
    text.TextHeight = 5;

    // second alignment point is required in case text is aligned (first alignment point is ignored)
    text.SecondAlignmentPoint = new Cad3DPoint(cadImage.Width / 2, cadImage.Height - text.TextHeight);
    
    text.HorizontalJustification = 1;
    text.ObjectHandle = "bebebebe";//Guid.NewGuid().ToString();
    text.LayerName = "0";
    text.SoftOwner = cadImage.Layouts["Model"].BlockTableRecordHandle;
    cadImage.BlockEntities["*Model_Space"].AddEntity(text);


    // should be called because we need to add one more entity using new size of image
    cadImage.UpdateSize();

    // add polyline that is a border around the drawing
    CadLwPolyline lwPolyline = new CadLwPolyline();
    lwPolyline.Coordinates = new List<Cad2DPoint>();
    lwPolyline.Coordinates.Add(new Cad2DPoint(cadImage.MinPoint.X - 20, cadImage.MinPoint.Y - 20));
    lwPolyline.Coordinates.Add(new Cad2DPoint(cadImage.MinPoint.X - 20, cadImage.MaxPoint.Y + 20));
    lwPolyline.Coordinates.Add(new Cad2DPoint(cadImage.MaxPoint.X + 20, cadImage.MaxPoint.Y + 20));
    lwPolyline.Coordinates.Add(new Cad2DPoint(cadImage.MaxPoint.X + 20, cadImage.MinPoint.Y - 20));


    cadImage.BlockEntities["*Model_Space"].AddEntity(lwPolyline);

    // should be called because adding of new entity may change size of drawing
    cadImage.UpdateSize();

   // remove border polyline after drawing is updated
    cadImage.RemoveEntity(lwPolyline);

    CadRasterizationOptions rasterizationOptions = new CadRasterizationOptions();

    PdfOptions pdfOptions = new PdfOptions();
    pdfOptions.VectorRasterizationOptions = rasterizationOptions;

    cadImage.Save(outPath, pdfOptions);
}
