Graphics, Figures & Tables ⇒ Text selectable in Output after clipping

[hkyz]

I have a TikZ figure whose code I don't want to modify. I want some parts of this figure not to be displayed. So, I add a clipping code at the beginning. However, the texts in the clipped sections are still visible in the produced PDF if selected by mouse.

Consider the following minimal code:

Code: Select all

\documentclass{article}
\usepackage{tikz}

\begin{document}
  \begin{tikzpicture}
    \clip (0,0) rectangle (2,2);
    % Untouchable code begins
    \node at (1,1) {A};
    \node at (3,1) {B};
    % Untouchable code ends
  \end{tikzpicture}
\end{document}

The intention of the code is to clip off B. However, in the produced PDF, one can still select B with mouse.

How can I make sure that B is completely removed?

Thanks.
