如何使文本字段被隐藏? [英] How do I make text field to be hidden?

问题描述

我想用不可见的iTextSharp创建一个文本字段.这是我用来创建文本字段的代码:

I'd like to create a text field with iTextSharp that is not visible. Here's code I'm using to create a textfield:

TextField field = new iTextSharp.text.pdf.TextField(writer, new iTextSharp.text.Rectangle(x, y - h, x + w, y), name);
field.BackgroundColor = new BaseColor(bgcolor[0], bgcolor[1], bgcolor[2]);
field.BorderColor = new BaseColor(bordercolor[0], bordercolor[1], bordercolor[2]);
field.BorderWidth = border;
field.BorderStyle = PdfBorderDictionary.STYLE_SOLID;
field.Text = text;
writer.AddAnnotation(field.GetTextField());

推荐答案

在Java中， TextField 类具有名为

In Java, the TextField class has a method named setVisibility() inherited from its parent, the BaseField class. Possible values are:

• BaseField.VISIBLE ，
• BaseField.HIDDEN ，
• BaseField.VISIBLE_BUT_DOES_NOT_PRINT 和
• BaseField.HIDDEN_BUT_PRINTABLE .

在使用iTextSharp时，应查找 SetVisibility()方法或 Visibility 属性.

As you're using iTextSharp, you should look for a SetVisibility() method or a Visibility property.

使用另一个人在回答此问题时建议的渲染模式适用于写入内容流，XObject或外观的内容.您要隐藏一个字段，那是完全不同的.

Using a render mode as suggested by another person in answer to this question applies to content written to a content stream, XObject or appearance. You are asking to hide a field, and that's something completely different.
