iText7: Adding a PDF inside a Cell (cutoff at end of page)-CodePudding

We are creating a PDF, it contains a large table, with headers (bold), sub-headers (non bold), rows and cells.

One of the requirements is to add an already existing PDF (can be multiple pages) inside the cell (under the sub-header). And this is where we are struggling. What we have tried so far:

Converting the PDF to a FormXObject, and adding that into the cell.

FontProvider fontProvider = new FontProvider();
ConverterProperties props = new ConverterProperties();
props.SetFontProvider(fontProvider);

var historyId = text.Replace("=Spectec_template", "");

var pdfTemplate = templateToPdfClient.GetPdf(historyId, "HI").Result;
PdfDocument srcDoc = new PdfDocument(new PdfReader(pdfTemplate.FileStream));
for (int i = 1; i < srcDoc.GetNumberOfPages()   1; i  )
{
    Cell newCell = new Cell(1, columnInfo.ColumnSpan).SetFont(PdfFontFactory.CreateFont(_fontName));
    PdfPage origPage = srcDoc.GetPage(i);

    Rectangle rect = origPage.GetPageSize();
    PdfFormXObject pageCopy = origPage.CopyAsFormXObject(pdf);
    Image image = new Image(pageCopy);
    image.SetBorder(Border.NO_BORDER);
    image.SetMaxWidth(UnitValue.CreatePercentValue(100));
    image.SetMaxHeight(UnitValue.CreatePercentValue(50));

    Div div = new Div();
    div.Add(image.SetMaxWidth(UnitValue.CreatePercentValue(100)));

    newCell.Add(div);
    newCell = ApplyLayoutsToCell(newCell, cellStyles);
    table.AddCell(newCell);
}

But the end result is that we only see 1 page and it's completely overlapping at the end of the page.

When we set image.SetAutoScale(true); the PDF is visible but it's extremely small. When adding the Image to a Paragraph instead of a DIV the PDF pages display next to each other.

Any ideas, suggestions?

Thank you

Thanks to @mkl and @KJ I figured this out.

I ended up adding each PDF page in a new Cell, and setting the scaling of image to 0.6f.

for (int i = 1; i < srcDoc.GetNumberOfPages()   1; i  )
{
    newCell = new Cell(1, columnInfo.ColumnSpan).SetFont(PdfFontFactory.CreateFont(_fontName));

    PdfPage origPage = srcDoc.GetPage(i);

    PdfFormXObject pageCopy = origPage.CopyAsFormXObject(pdf);
    Image image = new Image(pageCopy);
    image.SetBorder(Border.NO_BORDER);
    image.Scale(0.6f, 0.6f);

    newCell.Add(image);
    newCell = ApplyLayoutsToCell(newCell, cellStyles);

    table.AddCell(newCell);
}
