AcroForm值压扁后失踪 [英] AcroForm values missing after flattening

问题描述

我用的LibreOffice 4.1.3.2产生一个可填写的PDF：

I'm using LibreOffice 4.1.3.2 to produce a fillable PDF:

1. 创建一个Writer文档


2. 设置一些文本和测试领域


3. 导出为PDF

与Acrobar阅读器打开PDF文件显示正确填写的PDF。结果
接下来，我用iTextSharp的5.4.5填写字段并保存扁平文件：

Opening pdf file with Acrobar Reader shows a correct fillable pdf.
Next I use iTextSharp 5.4.5 to fill fields and save flattened document:

var pdf = new PdfReader(srcFilename);
using (var fw = new FileStream(dstFilename, FileMode.Create))
{
    var stamper = new PdfStamper(pdf, fw);
    var f = stamper.AcroFields;

    f.SetField("field1", "John Doe");
    f.SetField("field2", "12/04/2013");
    stamper.FormFlattening = true;
    stamper.Close();
}
pdf.Close();

问题是，填充字段中的值完全新的文件消失！结果
我以为田均未发现或填充，但发现注释 stamper.FormFlattening = TRUE 字段值是否有保存的PDF !!结果
当然，我需要一个扁平的PDF ...

Problem is that filled fields values completely disappear in new document!
I thought fields were not found or filled, but discovered that commenting stamper.FormFlattening = true field values are there in saved pdf!!
Naturally I need a flattened pdf...

有没有解决这个？

推荐答案

在创建使用开放式办公形式，开放式办公室设置一个标志，告诉iText的不是创造亮相。如果你看一下 FillDataSheet 例如，你会看到我们有以下行覆盖此：

When creating a form using Open Office, Open Office sets a flag telling iText not to create appearances. If you look at the FillDataSheet example, you'll see that we override this with the following line:

fields.setGenerateAppearances(true);

在特定的C＃代码段，这将是：

In your specific C# snippet, that would be:

f.GenerateAppearances = true;

设置字段前​​设置此值是非常重要或外观将不会创建。

It's important to set this value before setting the fields or the appearances won't be created.
