Question

我使用itextSharp 4.1.6将AcroFields添加到现有PDF中，然后在第二步中使用内容填充这些字段。当我在Adobe Reader中打开这些文档时，我可以看到内容。当我尝试打印文档时，所有填充的字段都是空的。

可编辑和平展的PDF都会发生这种情况。＆＃39; GenerateAppearances＆＃39;设置为True。由于当前的许可证概念，我无法升级到另一个版本。我的代码：

var dlg = new OpenFileDialog
{
    FileName = "",
    Filter = @"pdf|*.pdf"
};
if (dlg.ShowDialog() != DialogResult.OK) return;

// first step: create field
var outputpath1 = Path.Combine(Path.GetTempPath(), string.Format("{0}.pdf", Guid.NewGuid().ToString("N")));
var pdfReader1 = new PdfReader(dlg.FileName);
var output1 = new FileStream(outputpath1, FileMode.Create, FileAccess.Write);
var stamper1 = new PdfStamper(pdfReader1, output1);
InsertTextfield(stamper1, 1, 20, 500, 150, 100, "test");
stamper1.Close();
pdfReader1.Close();

// second step: insert some text
var outputpath2 = Path.Combine(Path.GetTempPath(), string.Format("{0}.pdf", Guid.NewGuid().ToString("N")));
var pdfReader2 = new PdfReader(outputpath1);
var output2 = new FileStream(outputpath2, FileMode.Create, FileAccess.Write);
var stamper2 = new PdfStamper(pdfReader2, output2);
stamper2.AcroFields.GenerateAppearances = true;
var formData = stamper2.AcroFields;
formData.SetField("test", "Lorem ipsum dolor sit amet, consectetur adipiscing elit. ");
stamper2.Close();
pdfReader2.Close();

Process.Start(outputpath2);

InsertTextField：

private static void InsertTextfield(PdfStamper stamper, int page, float x, float y, float width, float height, string fieldname)
{
    var field = PdfFormField.CreateTextField(stamper.Writer, true, false, 500);
    field.SetWidget(new Rectangle(x, y, x + width, y + height), PdfAnnotation.HIGHLIGHT_INVERT);
    field.SetFieldFlags(PdfAnnotation.FLAGS_PRINT);
    field.FieldName = fieldname;
    stamper.AddAnnotation(field, page);
}

对于文档，只需创建一个新的word文档，添加一些文本并另存为PDF。选择此文档开始。

那么，我怎样才能将我提交的内容显示在印刷品中？

编辑：添加了代码

您应该通过TextField构造函数创建TextField 适用于iTextSharp 4.1.6

private static void InsertTextfield(PdfStamper stamper, int page, float x, float y, float width, float height, string fieldname)
{
    var field = new TextField(stamper.Writer, new Rectangle(x, y, x + width, y + height), fieldname);
    field.Options = TextField.MULTILINE;
    stamper.AddAnnotation(field.GetTextField(), page);
}

印刷的Pdf显示没有填充的AcroForms的内容
