# How to set the border color in PDF forms to none?

I want to set the color of the border for my text fields to be none. But the parameter doesn't seem to accept none as a value. Here is an example:

\documentclass[12pt]{article}
\usepackage{hyperref}
\usepackage{xcolor}

\begin{document}

\begin{Form}
\TextField[name=formname,bordercolor=none,width=6cm] {\mbox{}}
\end{Form}

\end{document}


Is there a way to make this work?

Also with the backgroundcolor parameter.

I found the solution below by chance. I am posting this since I think this might be useful for others who might face the issue. – Kaveh Dec 6 '13 at 21:22

The solution is to leave the value empty and use bordercolor=. Here is the example:

\documentclass[12pt]{article}
\usepackage{hyperref}
\usepackage{xcolor}

\begin{document}

\begin{Form}
\TextField[name=formname,bordercolor=,width=6cm] {\mbox{}}
\end{Form}

\end{document}

bordercolor={1 1 1} (white) also works, although it is not a documented default. – alfC Sep 9 '15 at 18:46
@alfC, I don't want it to be white, I want it to be none. are you sure the resulting color in the pdf has value none? – Kaveh Sep 9 '15 at 19:36
Sorry, I don't know enough of the PDF format to know if bordercolor= means white or none at the end. What is none supposed to mean? Transparent? I don't know if that is supported. Maybe a true none is simply to set the borderwidth=0pt like the other answer. It cab tested in a colored background. – alfC Sep 9 '15 at 19:45
@alfC, none is a value for color that pdf supports. Yes, the result is transparent (regarding width 0 see my comment below). – Kaveh Sep 9 '15 at 19:52

The standard way is probably to set borderwidth to zero so no border is added. (Leaving bordercolor the empty string doesn't seem to be a supported value as far as I can see, even though it may not give an error message)

\documentclass[12pt]{article}
\usepackage{hyperref}
\usepackage{xcolor}

\begin{document}

\begin{Form}
\TextField[name=formname,borderwidth=0pt,,width=6cm] {\mbox{}}
\end{Form}

\end{document}

Thanks, I thought of this, but this won't work with other parameters like backgroundcolor which I want to set to none. Since PDF files support a none/no color value for these parameters the main point is how to access them from hyperref and leaving the value empty seems to do exactl that. hyperref package is not well-documented AFAIU. – Kaveh Dec 6 '13 at 22:42
How do we apply this solution to all the elements? – 71GA Aug 26 '14 at 23:34
