Itext Table Row , Table Header , Table cell - itext

I have a requirement to generated the PDF using itext in java
Need to generate the table with 3 rows and 2 columns , able to create the table.
Country Langugage
USA English
Canada French
When I was trying to read the pdf VIA NVDA Desktop App , the table is not reading the cells properly , say when I want to focus the pointer on Canada , it should the Country - Canada
Following is the code
public class Test {
public static final String CSS = "tr { text-align: center; } th { background-color: lightgreen; padding: 3px; } td {background-color: lightblue; padding: 3px; }";
public static void main(String sunil[])
{
String pFileName = "Test.pdf";
String pFilePath = "C:/local/home/dna/pushlive/" + pFileName;
try {
FileOutputStream baosPDF = new FileOutputStream(pFilePath);
com.itextpdf.text.Rectangle pageSize = new com.itextpdf.text.Rectangle(1836, 2376);
com.itextpdf.text.Document document = new com.itextpdf.text.Document(pageSize, 36, 36, 36, 36);
PdfWriter writer = PdfWriter.getInstance(document, baosPDF);
writer.setTagged();
document.open();
PdfPTable bannerTable = new PdfPTable(4);
document.add(createFirstTable());
document.close();
} catch (FileNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (DocumentException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
public static PdfPTable createFirstTable() {
// a table with three columns
PdfPTable table = new PdfPTable(2);
// the cell object
PdfPCell cell;
// we add a cell with colspan 3
//create header cell for first row
// now we add a cell with rowspan 2
//add metadata for each cell in the body.
// we add the four remaining cells with addCell()
cell = new PdfPCell(new Phrase("Country"));
table.addCell(cell);
cell = new PdfPCell(new Phrase("Language"));
table.addCell(cell);
cell = new PdfPCell(new Phrase("USA"));
table.addCell(cell);
cell = new PdfPCell(new Phrase("English"));
table.addCell(cell);
cell = new PdfPCell(new Phrase("Canada"));
table.addCell(cell);
cell = new PdfPCell(new Phrase("French"));
table.addCell(cell);
//set header row for the table
table.setHeaderRows(1);
return table;

iText PDF/A-2 Java add total page count in footer

I need to add the total page count to a PDF/A-2 document created using iText in Java. The following code is being used:
public class HeaderFooterPageEvent extends PdfPageEventHelper {
Font fontHEADER = null;
/** The template with the total number of pages. */
PdfTemplate total;
public HeaderFooterPageEvent() {
try {
fontHEADER = new Font(BaseFont.createFont("OpenSans-Regular.ttf", BaseFont.IDENTITY_H, BaseFont.EMBEDDED), 8, Font.BOLD);
} catch (DocumentException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
}
#Override
public void onOpenDocument(PdfWriter writer, Document document) {
total = writer.getDirectContent().createTemplate(30, 16);
super.onOpenDocument(writer, document);
}
#Override
public void onCloseDocument(PdfWriter writer, Document document) {
PdfContentByte cb = writer.getDirectContent();
ColumnText.showTextAligned(total, Element.ALIGN_RIGHT,
new Phrase(String.valueOf(writer.getPageNumber() - 1)),fontHEADER),
document.right() - document.rightMargin()+5,
document.bottom() - 10, 0);
super.onCloseDocument(writer, document);
}
}
And when creating the PDF the following code is called:
Document document = new Document(PageSize.A4, 15, 15, 30, 20);
PdfAWriter writer = PdfAWriter.getInstance(document, new FileOutputStream(dest), PdfAConformanceLevel.PDF_A_2A);
writer.createXmpMetadata();
writer.setTagged();
// add header and footer
HeaderFooterPageEvent event = new HeaderFooterPageEvent();
writer.setPageEvent(event);
document.open();
document.addLanguage("en-us");
File file = new File("sRGB_CS_profile.icm");
ICC_Profile icc = ICC_Profile
.getInstance(new FileInputStream(file));
writer.setOutputIntents("Custom", "", "http://www.color.org", "sRGB IEC61966-2.1", icc);
Paragraph p=new Paragraph("Page 1 content",fontEmbedded); //setting an embedded font
p.setSpacingBefore(30f);
document.add(p);
document.newPage();
document.add(new Paragraph("Content of next page goes here",fontEmbedded));
document.close();
Now when we add content on 2 pages and use document.newPage() to add the new page, runtime exception is generated The page 3 was requested but the document has only 2 pages. What is a solution to this problem?

iText 5 Add a text field under a paragraph

I'm using iText to create a PDF in my java spring mvc web project. I'm new to iText 5. Could anyone tell me how to add a text field under a paragraph? Based on my current code, the text field is not displayed under the paragraph. I may add more questions to the PDF so I want to display each text field under the paragraph.
try {
List<FormQuestionBean> questions = formBuilderBean.getQuestions();
MyHeaderAndFooter event = new MyHeaderAndFooter();
Document pdfDocument = new Document(PageSize.A4);
pdfDocument.setMargins(20, 20, 20, 30);
ByteArrayOutputStream pdfBaos = new ByteArrayOutputStream();
PdfWriter writer = PdfWriter.getInstance(pdfDocument, pdfBaos);
writer.setPageEvent(event);
pdfDocument.open();
Paragraph paragraph1 = new Paragraph(FORM_NAME + " : " + formBuilderBean.getName(), HEADING);
paragraph1.setSpacingAfter(20);
pdfDocument.add(paragraph1);
for (FormQuestionBean formQuestionBean: questions) {
if (formQuestionBean.getFieldImplementation().contentEquals("Text Field")) {
Paragraph p = new Paragraph(formQuestionBean.getName());
pdfDocument.add(p);
TextField text = new TextField(writer, new Rectangle(36, 788, 559, 806), "text" );
text.setBackgroundColor(BaseColor.WHITE);
PdfFormField field = text.getTextField();
writer.addAnnotation(field);
}
}
pdfDocument.close();
response.reset();
response.setHeader("Content-Length", String.valueOf(pdfBaos.size()));
response.setContentType("application/pdf");
response.setContentLength(pdfBaos.size());
String downloadName = getFormFileName(".pdf");
response.setHeader("Content-Disposition", "attachment; filename=\"" + downloadName + "\"");
OutputStream outputStream = response.getOutputStream();
pdfBaos.writeTo(outputStream);
outputStream.flush();
outputStream.close();
return true;
} catch (Exception e) {
logger.error(e);
e.printStackTrace();
return false;
}
I figured out using table and cell. Below is the code:
try {
List<FormQuestionBean> questions = formBuilderBean.getQuestions();
MyHeaderAndFooter event = new MyHeaderAndFooter();
Document pdfDocument = new Document(PageSize.A4);
pdfDocument.setMargins(20, 20, 20, 30);
ByteArrayOutputStream pdfBaos = new ByteArrayOutputStream();
PdfWriter writer = PdfWriter.getInstance(pdfDocument, pdfBaos);
writer.setPageEvent(event);
pdfDocument.open();
Paragraph paragraph1 = new Paragraph(FORM_NAME + " : " + formBuilderBean.getName(), HEADING);
paragraph1.setSpacingAfter(20);
pdfDocument.add(paragraph1);
for (FormQuestionBean formQuestionBean: questions) {
if (formQuestionBean.getFieldImplementation().contentEquals("Text Field")) {
PdfPTable table = new PdfPTable(1);
table.getDefaultCell().setBorder(Rectangle.NO_BORDER);
PdfPCell c1 = new PdfPCell(new Phrase(formQuestionBean.getName()));
c1.setFixedHeight(30);
table.addCell(c1);
PdfPCell c2 = new PdfPCell();
TextField text = new TextField(writer, c2, "text" );
text.setBackgroundColor(BaseColor.WHITE);
FieldPositioningEvents events = new FieldPositioningEvents(writer, text.getTextField());
c2.setCellEvent(events);
c2.setFixedHeight(30);
table.addCell(c2);
pdfDocument.add(table);
}
}
pdfDocument.close();
response.reset();
response.setHeader("Content-Length", String.valueOf(pdfBaos.size()));
response.setContentType("application/pdf");
response.setContentLength(pdfBaos.size());
String downloadName = getFormFileName(".pdf");
response.setHeader("Content-Disposition", "attachment; filename=\"" + downloadName + "\"");
OutputStream outputStream = response.getOutputStream();
pdfBaos.writeTo(outputStream);
outputStream.flush();
outputStream.close();
return true;
} catch (Exception e) {
logger.error(e);
e.printStackTrace();
return false;
}

Header and footer with content, itextpdf

My problem is when I try to add the content in the pdf, my table appears from the beginning and not below the header, my table with content has an incorrect height
The code is something long and I can not upload images, but I have a header and footer with pagination
It looks like it's just adding a space to my table with content but I do not know how to do it, I think my problem is in the summary method
private void addHeader(PdfWriter writer) {
PdfPTable tableHeader = new PdfPTable(2);
try {
// set default
tableHeader.setWidths(new int[] { 2, 24 });
tableHeader.setTotalWidth(527);
tableHeader.setLockedWidth(true);
tableHeader.getDefaultCell().setFixedHeight(40);
tableHeader.getDefaultCell().setBorder(Rectangle.BOTTOM);
tableHeader.getDefaultCell().setBorderColor(BaseColor.LIGHT_GRAY);
// addImage
Image img = Image.getInstance(getClass().getClassLoader().getResource("imgPDF/logo.png"));
tableHeader.addCell(img);
// addText
PdfPCell text = new PdfPCell();
text.setPaddingBottom(15);
text.setPaddingLeft(10);
text.setBorder(Rectangle.BOTTOM);
text.setBorderColor(BaseColor.LIGHT_GRAY);
text.addElement(new Phrase(cve.getId(), new Font(Font.FontFamily.HELVETICA, 13)));
text.addElement(new Phrase("https://myapp.com", new Font(Font.FontFamily.HELVETICA, 10)));
tableHeader.addCell(text);
// write content
tableHeader.writeSelectedRows(0, -1, 34, 803, writer.getDirectContent());
} catch (DocumentException e) {
throw new ExceptionConverter(e);
} catch (MalformedURLException e) {
throw new ExceptionConverter(e);
} catch (IOException e) {
throw new ExceptionConverter(e);
}
private void summary() throws IOException, DocumentException {
PdfPTable table = new PdfPTable(2);
table.setHeaderRows(0);
table.setWidthPercentage(100);
table.setSpacingBefore(15);
table.setTotalWidth(100);
// Add headers
table.addCell(createHeaderCellWithColor("Summary"));
table.addCell(createHeaderCellWithColor("ACCESS"));
table.addCell(createCell("row 1"));
table.addCell(createCell("row 2"));
table.addCell(createCell("row 3"));
PdfPTable table3 = new PdfPTable(3);
PdfPCell cell = new PdfPCell(new Phrase("aaa"));
cell.setColspan(3);
table3.addCell(cell);
table.addCell(createHeaderCellWithColor("IMPACT"));
document.add(table);
With this I largely resolve,
document = new Document (PageSize.A4, 36, 36, 90, 36);
Although I would like to download more content, and that is not so close to the header
Previously had this method with a parameter equal to 15, making the content below the header, this more separate ,,, simply equals the fill
solved with
text.setPaddingBottom(8);

Unable to left-align nested tables inside a cell

the following code does produce the table and the nested table.
However, the nested table is always aligned in the middle.
I have no clue how to achieve horizontal alignment properly.
The following method is simply looping through a list.
when it's a simple question, I will add an TextField.
if it's a question containing multiple answers, i will inject a nested table with the checkboxes and the values.
private PdfPTable CreateQuestionTable(RLQuestionRecordList questions)
{
PdfPCell cell;
PdfPTable table = new PdfPTable(2);
//table.SetWidths(new int[]{ 50, 50 });
table.WidthPercentage = 100;
table.SpacingBefore = 20;
table.SpacingAfter = 20;
table.DefaultCell.HorizontalAlignment = Element.ALIGN_LEFT;
foreach (RCQuestionRecord q in questions)
{
//add question to the table
cell = new PdfPCell(new Phrase(q.ssSTQuestion.ssName, _Normal));
cell.Border = Rectangle.NO_BORDER;
cell.Padding = 5.0f;
table.AddCell(cell);
//add answer to the table.
//add generate time we don;t know where the table will be,
//hence textfields will be generated after the pdf has been generated..
if (q.ssSTQuestion.ssListOfAnswers.Length > 0)
{
// we have radiobuttons, so we add a table inside the cell
cell = new PdfPCell();
cell.Border = Rectangle.NO_BORDER;
cell.Padding = 5.0f;
//we cannot align the table to the left in the cell for some weird reason...
cell.HorizontalAlignment = Element.ALIGN_LEFT;
cell.AddElement(CreateCheckboxTable(q));
table.AddCell(cell);
}
else
{
// we have simple textfield, so add that to the cell
cell = new PdfPCell();
cell.Border = Rectangle.NO_BORDER;
cell.Padding = 5.0f;
cell.HorizontalAlignment = Element.ALIGN_LEFT;
//simple textfield
cell.CellEvent = new OOMTextField(string.Format("question_{0}", q.ssSTQuestion.ssQuestionId), q.ssSTQuestion.ssLength, q.ssSTQuestion.ssValue, bf);
table.AddCell(cell);
}
}
return table;
}
This is the nested table I want to insert into the cell above.
/// <summary>
///
/// </summary>
/// <param name="question"></param>
/// <returns></returns>
private PdfPTable CreateCheckboxTable(RCQuestionRecord question)
{
PdfPCell cell;
int numCells = question.ssSTQuestion.ssListOfAnswers.Length;
PdfPTable table = new PdfPTable(numCells);
float[] widths = new float[numCells];
int currentColumn = 0;
//table.SetWidths(new int[]{ 50, 50 });
foreach (RCAnswerRecord a in question.ssSTQuestion.ssListOfAnswers) {
//checkbox
cell = new PdfPCell(new Phrase(a.ssSTAnswer.ssLabel, _Normal));
cell.Border = Rectangle.NO_BORDER;
cell.Padding = 0.0f;
cell.PaddingLeft = 20.0f;
cell.HorizontalAlignment = Element.ALIGN_LEFT;
cell.VerticalAlignment = Element.ALIGN_CENTER;
cell.CellEvent = new OOMCheckBox(string.Format("question_{0}", question.ssSTQuestion.ssQuestionId), a.ssSTAnswer.ssIsSelected, a.ssSTAnswer.ssLabel, bf);
//checkbox
table.AddCell(cell);
widths[currentColumn++] = 20.0f + bf.GetWidthPoint(a.ssSTAnswer.ssLabel, 11);
}
table.SetTotalWidth(widths);
table.LockedWidth = true;
table.SpacingBefore = 0;
return table;
}
What am I missing to align the nested tables totally to the left inside the cell?
Please take a look at the PDF document named nested_tables_aligned.pdf:
The outer table in this example has three columns and one row. Each cell in this outer table contains an inner table. The first inner table is left aligned, the second one is center aligned, the third one is right aligned.
This PDF was created with the Java example named NestedTablesAligned:
public void createPdf(String dest) throws IOException, DocumentException {
Document document = new Document(PageSize.A4.rotate());
PdfWriter.getInstance(document, new FileOutputStream(dest));
document.open();
float[] columnWidths = {200f, 200f, 200f};
PdfPTable table = new PdfPTable(columnWidths);
table.setTotalWidth(600f);
table.setLockedWidth(true);
buildNestedTables(table);
document.add(table);
document.close();
}
private void buildNestedTables(PdfPTable outerTable) {
PdfPTable innerTable1 = new PdfPTable(1);
innerTable1.setTotalWidth(100f);
innerTable1.setLockedWidth(true);
innerTable1.setHorizontalAlignment(Element.ALIGN_LEFT);
innerTable1.addCell("Cell 1");
innerTable1.addCell("Cell 2");
outerTable.addCell(innerTable1);
PdfPTable innerTable2 = new PdfPTable(2);
innerTable2.setTotalWidth(100f);
innerTable2.setLockedWidth(true);
innerTable2.setHorizontalAlignment(Element.ALIGN_CENTER);
innerTable2.addCell("Cell 3");
innerTable2.addCell("Cell 4");
outerTable.addCell(innerTable2);
PdfPTable innerTable3 = new PdfPTable(2);
innerTable3.setTotalWidth(100f);
innerTable3.setLockedWidth(true);
innerTable3.setHorizontalAlignment(Element.ALIGN_RIGHT);
innerTable3.addCell("Cell 5");
innerTable3.addCell("Cell 6");
outerTable.addCell(innerTable3);
}
As you can see, I define the alignment of the table at the level of the table, not at the level of the cell. The sample principle applies to iTextSharp. In you C# example, you define the aligned for the PdfPCell instead of for the PdfPTable. Change this and your problem will be solved.

How to insert blank lines in PDF?

I am creating a PDF using iText. I want to insert blank lines between paragraphs and tables.
How can I achieve this?
You can trigger a newline by inserting Chunk.NEWLINE into your document. Here's an example.
public static void main(String args[]) {
try {
// create a new document
Document document = new Document( PageSize.A4, 20, 20, 20, 20 );
PdfWriter.getInstance( document, new FileOutputStream( "HelloWorld.pdf" ) );
document.open();
document.add( new Paragraph( "Hello, World!" ) );
document.add( new Paragraph( "Hello, World!" ) );
// add a couple of blank lines
document.add( Chunk.NEWLINE );
document.add( Chunk.NEWLINE );
// add one more line with text
document.add( new Paragraph( "Hello, World!" ) );
document.close();
}
catch (Exception e) {
e.printStackTrace();
}
}
Below is a screen shot showing part of the PDF that the code above produces.
And to insert blank line between tables you can use these both methods
table.setSpacingBefore();
table.setSpacingAfter();
You can use "\n" in Paragraph
document.add(new Paragraph("\n\n"));
You can try a blank phrase:
document.add(new Phrase("\n"));
You can add Blank Line throw PdfContentByte class in itextPdf. As shown below:
package com.pdf.test;

}
document.add(new Paragraph(""))
It is ineffective above,must add a blank string, like this:
document.add(new Paragraph(" "));
You can add empty line ;
Paragraph p = new Paragraph();
// add one empty line
addEmptyLine(p, 1);
// add 3 empty line
addEmptyLine(p, 3);
private static void addEmptyLine(Paragraph paragraph, int number) {
for (int i = 0; i < number; i++) {
paragraph.add(new Paragraph(" "));
}
}
You can also use
document.add(new Paragraph());
document.add(new Paragraph());
before seperator if you are using either it is fine.
Instead of using:
document.add( Chunk.NEWLINE );
use this:
document.add(new Paragraph(""));
it makes small space
directly use
paragraph.add("\n");
to add an empty line.
I posted this in another question, but I find using tables with iTextSharp offers a great level of precision.
document.Add(BlankLineDoc(16));
public static PdfPTable BlankLineDoc(int height)
{
var table = new PdfPTable(1) {WidthPercentage = 100};
table = BlankLineTable(table, height);
return table;
}
public static PdfPTable BlankLineTable(PdfPTable table, int height, int border = Rectangle.NO_BORDER)
{
var cell = new PdfPCell(new Phrase(" "))
{
Border = border,
Colspan = table.NumberOfColumns,
FixedHeight = height
};
table.AddCell(cell);
return table;
}
BlankLineTable can be used directly when working with tables
I had to add blank lines after a table and I manage it adding many divs as I need it with a css style with padding-top set it up, like this. I've used a template engine (underscore) to loop through the number of lines I need to add.
<% var maxRow = 30; var pos = items.models.length; %>
<% for( pos; pos < maxRow; pos++ ){ %>
<div class="blankRow"></div>
<% }; %>
My css file:
.blankRow:{ padding-top: 15px;}
