Itextpdf adding a caption under an image

Is it possible in the same cell to add an image and it's caption ?
I've tried with a paragraph but with no luck.
Image img = null;
try {
img = Image.getInstance(Base64.decode(val));
} catch (Exception e) {
throw new Exception("Problem in decoding image");
}
Paragraph paragraph = new Paragraph("this is a Caption");
valueCell.setImage(img);
valueCell.addElement(paragraph);
Create a subtable with two cell, one with the image and the other one with the caption I think Is gonna mess with some logic used in this table that is composed of key/value pair cells.

I resolved using the addElement method.
PdfPCell valueCell = new PdfPCell();
Paragraph paragraph = new Paragraph("this is a Caption");
valueCell.addElement(img);
valueCell.addElement(paragraph);

OpenPDF: Table not located in footer

When I add a table to the footer of the page, the footer resizes to the right size, however, the table does not stay within this footer, however it locates itself at the top of the page.
I have created a test scenario to illustrate what I mean.
public class TestClass {
public static void main(String[] args) {
try {
Document document = new Document(PageSize.A4);
PdfWriter writer = PdfWriter.getInstance(document, new FileOutputStream("fail.pdf"));
PdfPTable table = new PdfPTable(2);
table.setWidthPercentage(100);
table.addCell(new PdfPCell(new Paragraph("CONTENT")));
table.addCell(new PdfPCell(new Paragraph("CONTENT")));
Paragraph footerParagraph = new Paragraph();
footerParagraph.add(table);
HeaderFooter footer = new HeaderFooter(footerParagraph, false);
footer.setAlignment(Element.ALIGN_CENTER);
document.setFooter(footer);
document.open();
document.add(new Paragraph("Hello World"));
document.close();
} catch (Exception ex) {
System.out.println(ex);
}
}
}
In this example the the footer has the correct size for the table:
However as mentioned the table is not located at the bottom, but at the top:

You need to know the page size and calculate from there.
You can use
showTextAligned(ELEMENT.ALIGN_BOTTOM)

This was a bug with OpenPDF, which should have been fixed now.

how to place text and images in small sized page using iText

I need to make a PDF page that looks something like this:
I'm having problems to make two columns that fit on a small sized page.
This is my code:
public void createSizedPdf(String dest) throws IOException, DocumentException {
Document document = new Document();
PdfWriter writer = PdfWriter.getInstance(document, new FileOutputStream(dest));
document.setMargins(5,5,5,5);
Rectangle one = new Rectangle(290,100);
one.setBackgroundColor(Color.YELLOW);
document.setPageSize(one);
document.open();
Paragraph consigneeName = new Paragraph("Ahmed");
Paragraph address = new Paragraph("Casa ST 121");
String codeBL = "14785236987541";
PdfContentByte cb = writer.getDirectContent();
Barcode128 code128 = new Barcode128();
code128.setBaseline(9);
code128.setSize(9);
code128.setCode(codeBL);
code128.setCodeType(Barcode128.CODE128);
Image code128Image = code128.createImageWithBarcode(cb, null, null);
Paragraph right = new Paragraph();
right.add(consigneeName);
right.add(address);
right.add(code128Image);
Chunk glue = new Chunk(new VerticalPositionMark());
Paragraph p = new Paragraph();
p.add(right);
p.add(new Chunk(glue));
p.add(code128Image);
document.add(p);
document.close();
}

One way to solve your problem, would be to create a template PDF with AcroForm fields. You could create a nice design manually, and then fill out the form programmatically by putting data (text, bar codes) at the appropriate places defined by the fields that act as placeholders.
Another way, is to create the PDF from scratch, which is the approach you seem to have taken, looking at your code.
Your question isn't entirely clear, in the sense that you share your code, but you don't explain the problem you are experiencing. As I already commented:
are you unable to scale images? are you unable to define a smaller
font size? are you unable to create a table with specific dimension?
You say I'm having problems to make two columns that fits in a small
sized page but you forgot to describe the problems.
You didn't give an answer to those questions, and that makes it very hard for someone to answer your question. The only thing a Stack Overflow reader could do, is to do your work in your place. That's not what Stack Overflow is for.
Moreover, the answer to your question is so trivial that it is hard for a Stack Overflow reader to understand why you posted a question.
You say you need to add data (text and bar codes) in two columns, you are actually saying that you want to create a table. This is an example of such a table:
If you look at the SmallTable example, you can see how it's built.
You want a PDF that measures 290 by 100 user units, with a margin of 5 user units on each side. This means that you have space for a table measuring 280 by 90 user units. Looking at your screen shot, I'd say that you have a column of 160 user units with and a column of 120 user units. I'd also say that you have three rows of 30 user units high each.
OK, then why don't you create a table based on those dimensions?
public void createPdf(String dest) throws IOException, DocumentException {
Rectangle small = new Rectangle(290,100);
Font smallfont = new Font(FontFamily.HELVETICA, 10);
Document document = new Document(small, 5, 5, 5, 5);
PdfWriter writer = PdfWriter.getInstance(document, new FileOutputStream(dest));
document.open();
PdfPTable table = new PdfPTable(2);
table.setTotalWidth(new float[]{ 160, 120 });
table.setLockedWidth(true);
PdfContentByte cb = writer.getDirectContent();
// first row
PdfPCell cell = new PdfPCell(new Phrase("Some text here"));
cell.setFixedHeight(30);
cell.setBorder(Rectangle.NO_BORDER);
cell.setColspan(2);
table.addCell(cell);
// second row
cell = new PdfPCell(new Phrase("Some more text", smallfont));
cell.setFixedHeight(30);
cell.setVerticalAlignment(Element.ALIGN_MIDDLE);
cell.setBorder(Rectangle.NO_BORDER);
table.addCell(cell);
Barcode128 code128 = new Barcode128();
code128.setCode("14785236987541");
code128.setCodeType(Barcode128.CODE128);
Image code128Image = code128.createImageWithBarcode(cb, null, null);
cell = new PdfPCell(code128Image, true);
cell.setBorder(Rectangle.NO_BORDER);
cell.setFixedHeight(30);
table.addCell(cell);
// third row
table.addCell(cell);
cell = new PdfPCell(new Phrase("and something else here", smallfont));
cell.setBorder(Rectangle.NO_BORDER);
cell.setHorizontalAlignment(Element.ALIGN_RIGHT);
table.addCell(cell);
document.add(table);
document.close();
}
In this example,
you learn how to change the font of the content in a cell,
you learn how to change horizontal and vertical alignment,
you learn how to scale a bar code so that it fits into a cell,
...
All of this functionality is explained in the official documentation. As I said before: you didn't explain the nature of your problem. What wasn't clear in the documentation for you? What is your question?

Itext PDF Cell rotation loses hyperlink

I am trying to create a lateral table with one of the cells being a hyperlink to a web site with iText 5.5.8. If I create a horizontal table, the result is ok:
File file = new File("c://temp//itext-test.pdf");
FileOutputStream fileout = new FileOutputStream(file);
Document document = new Document();
PdfWriter.getInstance(document, fileout);
document.open();
String stampedURL = "http://test.com";
URL validaURL = new URL(stampedURL);
try {
PdfPTable table = new PdfPTable(3); // 3 columns.
PdfPCell cell1 = new PdfPCell();
Chunk paragr = new Chunk("Click Here!");
PdfAction pdfAct = new PdfAction(validaURL);
paragr.setAction(pdfAct);
paragr.setAnchor(validaURL);
cell1.addElement(paragr);
PdfPCell cell2 = new PdfPCell(new Paragraph("Cell 2"));
PdfPCell cell3 = new PdfPCell(new Paragraph("Cell 3"));
table.addCell(cell1);
table.addCell(cell2);
table.addCell(cell3);
document.add(table);
document.close();
} catch(Exception e){
}
This code generates a horizontal table with 3 cells. The first one, contains an anchor and a pdfAction to a certain URL, so it is working fine.
To rotate the table, I simply rotate 90 degrees every cell. So before adding the cells to the table, I do:
cell1.setRotation(90);
cell2.setRotation(90);
cell3.setRotation(90);
Now I have rotated the cells, but the hyperlink has disappeared. I have been trying with several combinations, but with no luck.
Just to see if it was possible, I created a Word Document with rotated hyperlink in a cell, and then converted to PDF, and the link works... I know it is not a very helpful test, but just to try.
Any hint will be appreciated.
Thanks in advanced,
Xisco.

iText cell borders cutting through text

I am writing a program that generates a pdf or rtf file with a table in it, using iText. I used the iText class table and cell, rather than the more specific RtfTable or pdfTable so that either file can be generated at the end. I needed to set the cell padding to a value of -1, or else there was too much space between each row of data on the printed sheet. However, I am now trying to add borders (specifically to the pdf file), and the cells are not lining up with the text. The bottom border of each cell cuts directly through the text. It only actually surrounds the text when the cell padding is set to 2 or higher. Below is a sample of what I am doing:
Document document = new Document();
Paragraph paragraph = new Paragraph();
Font iTextFont = new Font(Font.TIMES_ROMAN, 9, Font.NORMAL);
try{
PdfWriter.getInstance(document, new FileOutputStream("C:/datafiles/TestiText.pdf"));
document.open();
Table table = new Table(3);
table.setPadding(-1);
table.setWidth(90);
Cell cell1 = new Cell();
cell1.setBorder(Rectangle.BOX);
cell1.setVerticalAlignment(ElementTags.ALIGN_TOP);
table.setDefaultCell(cell1);
paragraph = new Paragraph("header", iTextFont);
Cell cell = new Cell(paragraph);
cell.setHeader(true);
cell.setColspan(3);
table.addCell(cell);
paragraph = new Paragraph("example cell", iTextFont);
table.addCell(paragraph);
paragraph = new Paragraph("one", iTextFont);
table.addCell(cell);
paragraph = new Paragraph("two", iTextFont);
cell = new Cell(paragraph);
table.addCell(paragraph);
paragraph = new Paragraph("Does this start a new row?", iTextFont);
table.addCell(paragraph);
paragraph = new Paragraph("Four", iTextFont);
table.addCell(paragraph);
paragraph = new Paragraph("Five", iTextFont);
table.addCell(paragraph);
document.add(table);
} catch (Exception e) {
//handle exception
}
document.close();
}
Is there a way to resolve this issue either by moving the whole border down a drop (without affecting the text placement), or to get rid of the spaces between each line (spacing appears to only be a problem above the text, not below) without setting the cell padding to -1?

Write a class or common methods to build your table -- whether you're using Table or PdfPTable.
These methods will handle standard alignment, measurement based on ascenders/descenders, etc for you.. They also provide a common place to add a "3pt blank paragraph" or whatever other standard formattings, you may need.
OO software isn't meant to be about clanking out repetitive, and potentially inconsistent, sections of code.
Hope this helps.

you should use PdfPTable it has many method that is useful and well wrapped component
i posted this answer so any one faces the same problem know where to start
it might not be the typical answer to the question but here it comes...
