I want to have some text appear semi-transparent, but not in an overlay fashion (where it eventually becomes solid) just permanently semi-transparent. To complicate matters, the text in question is part of a matrix:

$\begin{matrix} & \{-2,3,5,0,8\} & \\ \{-2,3,5,0\} & & \{-2,3,5,8\} \\ & \{-2,3,5\} & \end{matrix}$


I want the third line in the matrix to be semi-transparent. Is there a way to do this?

Edit: improved the solution by turning it into a command with an optional argument.

Okay, discovered how to do it:

\newcommand{\semitransp}[2][35]{\color{fg!#1}#2}

...

$\begin{matrix} & \{-2,3,5,0,8\} & \\ \{-2,3,5,0\} & & \{-2,3,5,8\} \\ & \semitransp{\{-2,3,5\}} & \end{matrix}$


The optional parameter controls the transparency. So \semitransp[20]{text} is lighter, and \semitransp[60]{text} is heavier. The default value 35 looks good on my computer screen. It is yet to be seen how it looks projected on a wall.

How do I get transparent text? - TeX, Here is a non-TikZ solution. We specify the transparency using \transparent{<​value>} , where the value is from 0-1. Adjust the values to suit. If you want to break a line in the middle of a paragraph using the \linebreak command and if LaTeX thinks that is there is too little text left on the line to stretch it to full width, we receive a message like Underfull \hbox (badness 4328) in paragraph at lines 8—12. The variants of the command \\ are given below:

Ari's answer may work for him (and in 2010), but the given command will make all following text transparent, not only the given text.

An improved solution for making only the given text transparent:

\newcommand{\semitransp}[2][35]{\textcolor{fg!#1}{#2}}
% Swap \color with \textcolor and add another curly brackets pair.

...

$\begin{matrix} & \{-2,3,5,0,8\} & \\ \{-2,3,5,0\} & & \{-2,3,5,8\} \\ & \semitransp{\{-2,3,5\}} & \end{matrix}$


Partially transparent text box - TeX, The following was taken verbatim from the PGF documentation (section 20 Transparency, p 234):. enter image description here \documentclass{article}  I'm using beamer with xelatex to prepare a talk. If I switch on notes on right I'm experiencing strange behaviour: When using csqoutes in the title, all normal text afterwards becomes invisible (or white). The text selectable in the output pdf. Note that the text is also visible in the small preview on the note page.

To get real semi-transparency, one can use \pgfsetfillopacity. The advantage compared to faking the opacity by mixing the foreground colour with the background is, that this will also work if the there is a background image or some other coloured element.

I want to run this animation from he pdf file in a single beamer frame and run the animation with a gap of 1 second between each page of the pdf. How do I go about doing this? I use pdflatex. Let us say the pdf file has 100 pages and each page contains the image sequentially for the animation and the name of the pdf file is animation.pdf.
