Header is only shown on the first page

Aspose.PDF Product Family

Hello, working with aspose.pdf for net, I try to put a header on all the pages of an existing pdf and it only shows in the first one.

Code
byte[] IConversorPdf.CrearEncabezado(byte[] pdf, string html, string numeroDocumento, string secuencia, int margensuperior)
{
Aspose.Pdf.License licensepdf = new Aspose.Pdf.License();
licensepdf.SetLicense(“Aspose.Total.lic”);
licensepdf.Embedded = true;
Stream streamPdf = new MemoryStream();
streamPdf.Write(pdf, 0, pdf.Length);
Aspose.Pdf.Document pdfDocument = new Aspose.Pdf.Document(streamPdf) {OptimizeSize = true};
Aspose.Pdf.HeaderFooter header = new Aspose.Pdf.HeaderFooter();
html = html.Replace("%%NUMERODOCUMENTO%%", numeroDocumento).Replace("%%SECUENCIA%%", secuencia);
HtmlFragment htmlstring = new HtmlFragment(html)
{
Margin = {Top = margensuperior},
HorizontalAlignment = HorizontalAlignment.Center
};
header.Paragraphs.Add(htmlstring);
foreach (Page page in pdfDocument.Pages)
{
page.Header = header;
}
Stream stream = new MemoryStream();
pdfDocument.Save(stream);
return ConvertirStreamAArrayBytes(stream);
}

@acoviant7,

We have tested your scenario with the latest version 18.2 of Aspose.PDF for .NET API and can add HTML header to all pages. Kindly send us your source PDF sample and parameter values which you are using to call CrearEncabezado method. We will investigate your scenario in our environment. Your response is awaited.

Hello, this is the code that we use to convert to pdf and add the headers and footers when they correspond:

private void ProcesarOrdenConversion(OrdenConversion ordenConversion, string pEntorno)
{
Entorno entorno = ManagerEntornosConfig.Instance.GetEntornoByName(pEntorno);

        //Carga el blob original en la orden de conversion
        ordenConversion.Archivo = ServicioBlobProxy.ObtenerDocumentoOriginal(entorno.Servicio, false, ordenConversion.BlobId);

        //convierte a pdf
        ordenConversion.Archivo.ArrayDatos = ConversorPdf.CrearPDF(ordenConversion.Archivo.ArrayDatos,
        , (ordenConversion.AltoCabezal > 0 ? ordenConversion.AltoCabezal : 0) + ordenConversion.MargenSuperior);

        //agrega el cabezal
        if (ordenConversion.AgregarCabezal == Constantes.Verdadero)
        {
            //Obtenemos el archivo original
            Archivo cabezal = ServicioBlobProxy.ObtenerDocumentoOriginal(entorno.Servicio, false, ordenConversion.BlobCabezalId);
            string html = System.Text.Encoding.UTF8.GetString(cabezal.ArrayDatos);
            ordenConversion.Archivo.ArrayDatos = ConversorPdf.CrearEncabezado(ordenConversion.Archivo.ArrayDatos, html, ordenConversion.NumeroDocumento, ordenConversion.NumeroSecuencia.ToString(), ordenConversion.MargenSuperior);
        }
            
        //Graba el archivo convertido a PDF.
        int idBlobPdf = ServicioBlobProxy.GrabarDocumentoPDF(entorno.Servicio, ordenConversion.BlobIndexable == 1, ordenConversion.Archivo, ordenConversion.TipoContenido);
        //setea el ID del nuevo blob
        ordenConversion.CargarBlodPDF(idBlobPdf);

        //Paso la orden a Estado Convertido
        Estado estadoConvertida = ConversionRepositorio.ObtenerEstado(Enumerados.EstadoOrdenConversion.Convertida.ToString());
        ordenConversion.CambiarEstado(estadoConvertida);
        UnitOfWork.Commit();
    }

These are the codes of the main functions that are referenced:

byte[] IConversorPdf.CrearPDF(byte[] documentArray, double margenSuperior)
{
Aspose.Words.License licensewords = new Aspose.Words.License();
licensewords.SetLicense(“Aspose.Total.lic”);
MemoryStream outStream = null;
Stream stream = null;
byte[] retorno;
try
{
stream = new MemoryStream(documentArray);
var doc = new Aspose.Words.Document(stream);
foreach (Aspose.Words.Section sec in doc.Sections)
{
Aspose.Words.PageSetup ps = sec.PageSetup;
ps.TopMargin = margenSuperior;
}
outStream = new MemoryStream();
var so = Aspose.Words.Saving.SaveOptions.CreateSaveOptions(Aspose.Words.SaveFormat.Pdf);
so.MemoryOptimization = true;
doc.Save(outStream, so);
retorno = outStream.ToArray();
}
finally
{
if (outStream != null)
outStream.Close();
if (stream != null)
stream.Close();
GC.Collect();
}
return retorno;
}

@acoviant7,

We have tested your scenario with the latest version of Aspose.PDF for .NET 18.2 and Aspose.Words for .NET 18.3. We can add header on the second page, but the image is missing and the text formatting is also incorrect. We have logged an investigation under the ticket ID PDFNET-44341 in our bug tracking system and will keep you informed regarding any available updates. This is the output PDF: FicheroSalida.pdf (86.1 KB)
