增加AcroFields的宽度（iTextSharp） [英] increase width of AcroFields(iTextSharp)

问题描述

我正在使用iTextSharp将数据填充到PDF模板，这是在OpenOffice中创建的。它填充得很好，我得到了正确的PDF，但有些我想增加AcroField的宽度。

我做了以下代码。它正在增加宽度，但文本没有显示。

  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））; 
} 
  

在下图中突出显示了一个。实际字符串是 10000 SUPERIOROPTICAL 123 4567 89

请帮助。

谢谢。

解决方案

我无法重现这个问题。我已经制作了这个POC：。

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.

解决方案

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.
