问题

I'm using iTextSharp to populate the data to PDF Templates, which is created in OpenOffice. it populating fine, I'm getting proper PDF, but some where i want to increase the width of the AcroField.

I did below code. it is increasing the width but text is not displaying.

AcroFields.Item fldItem = fields.getFieldItem(fieldName);
for (int i =0; i < fldItem.size(); ++i) {
  PdfDictionary widgetDict = fldItem.getWidget(0);
  PdfArray rectArr = widgetDict.getAsArray(PdfName.RECT); 
  float origX = rectArr.getAsNumber(0).floatValue();
  rectArr.set( 2, new PdfNumber( origX + 12 + 60 ) );
}  

in the below image highlighted one. actual string is 10000 SUPERIOROPTICAL 123 4567 89

please help.
thanks.

I can't reproduce the problem. I've made this POC: ChangeFieldSize

In this example, I take a form with three fields, among others a "Name" and a "Company" field. I first change the size of the "Name" field, the same way you change the field. Then I fill out the "Name" field and the "Company" field. Note that the order in which I perform these operations is important. Maybe you're doing it the other way round.

The result looks like this:

As you can see, the text isn't truncated the way it is in your screen shot.

So there are two things you can try:

• change the order in which you change the field rectangle and fill out the field.
• upgrade to the most recent version of iTextSharp.

If that doesn't help, post a SSCCE.
