To Add text into PDF file

Aspose.PDF Product Family
1

Hi Team,

Below is the code snippet wrote to add a simple text to PDF file using Aspose.Pdf contained classes. Though the file is created in the location, there is no content(i.e) assigned text in the output pdf file.


Pdf m_pdf = new Pdf();
Section section = m_pdf.Sections.Add();
Aspose.Pdf.Table pdfTable = new Aspose.Pdf.Table(section);
Aspose.Pdf.Row pdfRow = pdfTable.Rows.Add();
pdfRow.Cells.Add();
Aspose.Pdf.Cell pdfCell = new Aspose.Pdf.Cell(pdfTable);

Text pdfText = new Text();
TextInfo textInfo = pdfText.TextInfo;
Segment segment = pdfText.Segments.Add();
string tempString = "some text";
segment.Content = tempString;
textInfo = segment.TextInfo;
if (pdfText != null) pdfCell.Paragraphs.Add(pdfText);
section.Paragraphs.Add(pdfTable);
MemoryStream stream = new MemoryStream();
m_pdf.Save(@"c:\temp\test.pdf");

Please correct if i am missing any thing here.


Thanks,
Divya

Hi Divya,


Thanks for contacting support.

The reason you are getting blank PDF file is because you have mixed two namespaces i.e. Aspose.Pdf and Aspose.Pdf.Generator. The m_pdf object is created from Aspose.Pdf.Generator.Pdf class, whereas table object is created using Aspose.Pdf.Table class. The Text class is present under Aspose.Pdf.Generator namespace and you have tried adding it to cells objects created using Aspose.Pdf.Cell class. In order to generate correct output, try using either namespace i.e. Aspose.Pdf or Aspose.Pdf.Generator. Please take a look over following code snippet which generates correct output.

See attached sample PDF file.

[C#]

Aspose.Pdf.Document
m_pdf = new Aspose.Pdf.Document();<o:p></o:p>

// Pdf m_pdf = new Pdf();

// Aspose.Pdf.Generator.Section section = m_pdf.Sections.Add();

m_pdf.Pages.Add();

Aspose.Pdf.Table pdfTable = new Aspose.Pdf.Table();

pdfTable.ColumnWidths = "100";

pdfTable.Border = new Aspose.Pdf.BorderInfo(Aspose.Pdf.BorderSide.All, Aspose.Pdf.Color.Blue);

Aspose.Pdf.Row pdfRow = pdfTable.Rows.Add();

Aspose.Pdf.Cell pdfCell = new Aspose.Pdf.Cell();

pdfRow.Cells.Add(pdfCell);

Aspose.Pdf.Text.TextFragment pdfText = new Aspose.Pdf.Text.TextFragment("some text");

// TextInfo textInfo = pdfText.TextInfo;

// Segment segment = pdfText.Segments.Add();

// string tempString = "some text";

// segment.Content = tempString;

// textInfo = segment.TextInfo;

pdfCell.Paragraphs.Add(pdfText);

// section.Paragraphs.Add(pdfTable);

m_pdf.Pages[1].Paragraphs.Add(pdfTable);

// MemoryStream stream = new MemoryStream();

m_pdf.Save(@“c:\pdftest\SampleFile.pdf”);

Hi Nayyer,

The code you gave was useful though we are using Aspose PDF dll V4.0.0.0 and Aspose PDF Kit dll v3.4.0.0. The Classes Document and TextFragment are not available in those version. Could you please give me a sample snippet suporting the version which we are using?

Thanks,
Divya

Hi Divya,


The versions of API’s which you are using are quite old. However you may consider using the following code snippet to generate the correct output.

Please note that the reasons table object is not appearing in PDF document is because you have instantiated pdfCell object and have added the pdfText object to paragraphs collection of pdfCell. But you have not added the cell to cells collection of row object of table. In order to generate correct output, please try using following code snippet.

Also its recommended to set the column width for table object.

[C#]

Pdf m_pdf = new Pdf();<o:p></o:p>

Section section = m_pdf.Sections.Add();

Aspose.Pdf.Generator.Table pdfTable = new Aspose.Pdf.Generator.Table();

pdfTable.ColumnWidths = "60";

pdfTable.Border = new Aspose.Pdf.Generator.BorderInfo((int)Aspose.Pdf.Generator.BorderSide.All, new Aspose.Pdf.Generator.Color("Red"));

Aspose.Pdf.Generator.Row pdfRow = pdfTable.Rows.Add();

Aspose.Pdf.Generator.Cell pdfCell = new Aspose.Pdf.Generator.Cell(pdfRow);

pdfRow.Cells.Add(pdfCell);

Aspose.Pdf.Generator.Text pdfText = new Aspose.Pdf.Generator.Text();

TextInfo textInfo = pdfText.TextInfo;

Segment segment = pdfText.Segments.Add();

string tempString = "some text";

segment.Content = tempString;

textInfo = segment.TextInfo;

pdfCell.Paragraphs.Add(pdfText);

section.Paragraphs.Add(pdfTable);

m_pdf.Save(@"c:\pdftest\LegacyProduct_test.pdf");
