RE: [iText-questions] Text Overflow

float[] position = form.getFieldPositions(name);
   ColumnText text = new ColumnText(writer.getDirectContent());
   text.setSimpleColumn(position[1], position[2], position[3], position[4]);

text.setLeading(0, 1);
   text.addText(new Phrase(value));
  
   if ((text.go(true) & ColumnText.NO_MORE_TEXT) == 0)
       System.out.println("overflow");~

 

There are other factors like the font size and the font but this will get you going. I'll put in my to-do list direct support for this.

Hi Paulo,

 

I wrote the following code to do this.

 

    float[] position = form.getFieldPositions(name);
  
   float[] left = {position[1], position[2], position[3], position[2]};
   float[] right = {position[1], position[4], position[3], position[4]};

 

  PdfWriter writer = stamper.getWriter();
   
   ColumnText text = new ColumnText(writer.getDirectContent());
   text.setColumns(left, right);
   text.addText(new Phrase(value));
  
   if (text.go(true) == ColumnText.NO_MORE_COLUMN)
       System.out.println("overflow");

 

I get the following exception:

 

java.lang.RuntimeException: No valid column line found.

at com.lowagie.text.pdf.ColumnText.convertColumn(Unknown Source)

at com.lowagie.text.pdf.ColumnText.setColumns(Unknown Source)

I am just trying to simulate the creation of  a coulmn same size as that of the text field and see whether the data fits into it. 

I have no idea what I am doing wrong.

Another question : what is 'leading' in the method setSimpleColumn()? Javadoc does not say anything.

Thank you very much for your time.

Merlyn.

You have iText examples in the main site and in itextpdf.sf.net. See AcroFields.getFieldPositions() and the javadocs for ColumnText.

Hi,

 

Thank you so much for the reply. I am new to itext and I could not find it on the web. It would be very helpful if you could send me an example of how to get the field dimensions from pdfstamper object and to use columntext.

 

Thanks again

Merlyn.
