itext7 + pdfHtml: how set portrait orientation and fit content on ConvertToPdf - itext

Question

I did a simple html to pdf conversion getting a landscape orientation.
In the pdfHtml release notes I see that the default orientation should be portrait but I got a landscape.
I'm not able to find the option/parameter/setting to do it.
Probably it is in the ConverterProperties object hidden to my eyes :-(
Any suggestion?
Here is my very simple code
public byte[] HtmlToPdf(string html)
{
using (Stream htmlSource = new MemoryStream(Encoding.UTF8.GetBytes(html)))
using (MemoryStream pdfDest = new MemoryStream())
{
ConverterProperties converterProperties = new ConverterProperties();
HtmlConverter.ConvertToPdf(htmlSource, pdfDest, converterProperties);
return pdfDest.ToArray();
}
}
EDIT after answers (I got the right orientation!):
Now I have to find a way to scale down the content in order to fit the content and have the right margins without cutting the image.
public static byte[] HtmlToPdf(string html)
{
using (Stream htmlSource = new MemoryStream(Encoding.UTF8.GetBytes(html)))
using (MemoryStream pdfDest = new MemoryStream())
{
PdfDocument pdfDocument = new PdfDocument(new PdfWriter(pdfDest));
pdfDocument.SetDefaultPageSize(PageSize.A4.Rotate());
ConverterProperties converterProperties = new ConverterProperties();
HtmlConverter.ConvertToPdf(htmlSource, pdfDocument, converterProperties);
return pdfDest.ToArray();
}
}

Answer 1

I solved changing the library from itext7 to DinkToPdf. I found it very simple to use and enough to my needs.
The MVC controller after changing the library to DinkToPdf
public byte[] PdfCreatorController(IConverter converter)
string html = await reader.ReadToEndAsync();
var globalSettings = new GlobalSettings
{
ColorMode = ColorMode.Color,
Orientation = Orientation.Portrait,
PaperSize = PaperKind.A4,
Margins = new MarginSettings { Top = 10 },
DocumentTitle = "Report",
Out = string.Empty,
};
var objectSettings = new ObjectSettings
{
PagesCount = true,
HtmlContent = html,
WebSettings = { DefaultEncoding = "utf-8", UserStyleSheet = Path.Combine(Directory.GetCurrentDirectory(), "assets", "styles.css") },
};
var pdf = new HtmlToPdfDocument()
{
GlobalSettings = globalSettings,
Objects = { objectSettings }
};
return = _converter.Convert(pdf);
}
