missing line space in Text field while merging multiple PDF's using PDFCopy of IText

[shiva nanda]

Hi,

I am using IText to fill the values in Designer created PDF using IText AcroFields along with this I am using PDFCopy of Itext to merge the same pdf file for 3 times with different data. The issue is I am having text field in the pdf where it will accept multiple lines and I had given 8 inches as the line spacing between the lines. When i create a single pdf( i.e. filling values in the form and creating a new file) the line spacing is the same as what I had given but when I try to merge the three files the line spacing in the Text Field is getting increased and my data is over flowing. I am merging the files using PDFCopy.

My code will looks like the following

   

FileOutputStream os = new FileOutputStream("template.pdf");
		Document document = new Document();
		PdfCopy copy = new PdfCopy(document, os);
		document.open();
		
		for (int i =0;i<3;i++) {
			// create the reader by passing the AWB PDF template
			PdfReader reader = new PdfReader("template.pdf");
			FileOutputStream baos = new FileOutputStream("result.pdf");
			// create the stamper
			PdfStamper pdfStamper = new PdfStamper(reader, baos);
			pdfStamper.setFormFlattening(true);
			pdfStamper.setFreeTextFlattening(true);
			pdfStamper.setFullCompression();
			// retrieve the form fields
			AcroFields pdfForm = pdfStamper.getAcroFields();
			// fill the form with the appropriate values
			
			// This method will fill up the form values
			setFormValues(pdfForm);

			pdfStamper.setFormFlattening(true);
			pdfStamper.close();
			reader = new PdfReader("result.pdf");
			// add the first page of the reader to the copy
			copy.addPage(copy.getImportedPage(reader, 1));
			reader.close();
			baos.close();
		}
		copy.flush();
		document.close();
		copy.close();


 

Could any one please tell me what is the reason for increasing line space between the lines in Text fields


Thanks

Hi Shiva and welcome to Javaranch!

Is the PDFCopy a separate tool?

Hi Martijn,

PDFCopy is not a tool. It is a class in IText API. I debugged the issue and found the reason for line space. It is because of turning on PDFStamper and not the PDFCopy. FormFlattening to true. When i turn of the formFlattening the line spacing is appeairing. But not able to find the solution

Thanks,
Shiva

Hi Shiva,

Hmmm, sounds like a tricky internal API issue, have you tried on the iText/JasperReports forums?

Hi Martijn,

Yes. But no solution found . Anyways thanks for having a look into my post. Please let me know if you found any solution/clue.

Thanks,
Shiva
