如何生成带有绿色复选标记的签名PDF [英] How to generate a signed PDF w/o green checkmark

问题描述

我正在使用iText签署PDF文件。我在签名中加入了一个图形。这样可行，但显示文档验证时的绿色复选标记（或黄色问号）会干扰我插入的图形，使最终结果看起来很难看。

I'm signing PDF's using iText. I'm including a graphic in the signature. This works, but the green checkmark (or yellow question mark) that shows when the document is verified interferes with the graphic I inserted, making the end result look ugly.

它要么显示在签名图形的上方或下方，但是我不能让它消失。

It either shows up above or below the signature graphic, but I can't get it to disappear.

有谁知道如何解决这个问题？

Does anyone know how to fix this?

推荐答案

抱歉，但我不明白这一点。您想要一个有效的签名但不可能看到签名有效吗？对我没有意义。

sorry but I don't understand this. You want a valid signature but no possibility to see that the signature is valid? Doesn't make sense to me.

无论如何，我认为绿色复选标记由Adobe Reader呈现，因此您将无法删除它。

Anyway, I think the green checkmark is rendered by Adobe Reader so you will have no chance to remove it.
