I used to do this according to Andrew's solution until I read his note #2, and it reminded me that PGF's keys can do pretty much anything. The key (excuse the pun) is to create a key that processes other keys conditional on the slide number: \tikzset{onslide/.code args={<#1>#2}{% \only<#1>{\pgfkeysalso{#2}} }} Using \pgfkeysalso doesn't ...

The simplest way is to use the onimage package from the From Answers to Packages project, which implements the answer given in Drawing on an image with TikZ. To use the package: Download the file onimage.dtx from bazaar.launchpad.net/~tex-sx/tex-sx/development/files, run pdflatex on it, and move the resulting .sty file to your working directory. Then you ...

Wrap your code fragment inside the overlayarea environment.

This issue is addressed in the beamer manual in section 9.5 Dynamically Changing Text or Images, p.85 for v.3.10. You need to use either the overlayarea environment which is "more flexible but less user friendly" or the overprint environment. \begin{overlayarea}{⟨area width⟩}{⟨area height⟩} ⟨environment contents⟩ \end{overlayarea} ...

23

You can include the picture into a TikZ node and then draw some rectangles over it. For example, \documentclass{beamer} \usepackage[T1]{fontenc} \usepackage{tikz} \begin{document} \begin{frame} \frametitle{ESR1} \begin{center} Functional analysis \end{center} \begin{center} \begin{tikzpicture} ...

22

You can overlay the symbols the following way: Box the wider one and let the other one lap over it (using \rlap or \llap). The correct centering is achieved by placing the second character into a box with the equal width but using \hss to center it. The correct size for the different math modes can be adjusted using \mathchoice. \documentclass{article} ...

21

You could also use the Plain macro \ooalign: \mathrel{\ooalign{\hss?\hss\cr=}}\bye

In short, \only<>{} does not render the braced material at all except on the named slides, while \onslide<> renders the material until the next \onslide, sort of like an \item, but, on the off slides, covers it (according to the preference given in \setbeamercovered; i.e. transparent or invisible). There are other alternatives, for example, ...

Before looking at how . works, I think it's worth a brief look at how + works as in an overlay specification, and to link that to a 'plain' specification containing only explicit numbers. I'll take the offsets last, as they are more complex. For the simple case of just numbers \begin{itemize} \item<1-> From the first slide \item<2-> From ...

Use \layout form the layout package. This produces: and the details on the bottom: \documentclass{article} \usepackage{layout} \begin{document}\layout \end{document}

14

can also be done with a simple tabular \documentclass{article} \usepackage{xcolor,calc} \newcommand\strikeout[2][]{% \begin{tabular}[b]{@{}c@{}} \makebox(0,0)[cb]{\textcolor{blue}{#1}} \\[-0.2\normalbaselineskip] \rlap{\color{red}\rule[0.5ex]{\widthof{#2}}{0.5pt}}#2 \end{tabular}} \begin{document} Now is the the time for all good ...

It is possible to use a {tikzpicture} and overlay it: \documentclass[10pt]{beamer} \usetheme{Szeged} \usecolortheme{dolphin} \usepackage{fontspec} \usepackage{pgf} \usepackage{tikz} \setbeamercovered{transparent=25} %Uncover text transparently \begin{document} \begin{frame} \begin{itemize} \item<1> first item ...

2nd attempt (Warning: TikZ 3.0 is required!) Additional filled requirements (see 1st attempt below for all other filled requirements): Allow for "decay" via special prev styles. Each named keyword (such as kw) must provide three styles: kw, special kw and special prev kw. The names of "program counter" (\pc) and its previous value (\pcprev) can be chosen ...

13

You can use postaction and draw the patterns after filling. \documentclass[tikz,12pt]{standalone} \usetikzlibrary{patterns} \begin{document} \begin{tikzpicture}[line width=1.5pt] \coordinate (A) at (2,2); \coordinate (B) at (2,1.2); \coordinate (C) at (3,2); \coordinate (D) at (3,1.2); \draw[fill=white] (A) circle (0.5); \draw[fill=white, ...

The \caption command is not "overlay specification aware". Instead of \caption<1>{Hallo} \caption<2>{Welt} do \caption{\only<1>{Hallo}\only<2>{Welt}}

13

I can provide you a very basic solution: it is not perfect, but actually does what you wonder. Initially I defined two tikzstyles to characterize whether the block is alerted or not: \tikzset{visib/.style={rectangle,color=blue,fill=blue!10,text=black,draw,text opacity=0.4, text width=#1,align=flush center}} ...

12

Simply write \pause before the itemize environment. This will achieve the effect you want.

12

You can put \pause before the \begin{itemize} line.

Damn you Caramdir, four minutes too late! Anyway, here's what I came up with. Caramdir's is at least as good, but mine is a bit closer to your syntax, maybe... \documentclass[english,ignorenonframetext,table]{beamer} \usepackage[T1]{fontenc} \usepackage[latin9]{inputenc} \setcounter{secnumdepth}{3} \setcounter{tocdepth}{3} \usepackage{graphicx} ...

It's logic, captain, but not as we know it. The crucial fact to remember is that every time beamer sees a + then beamerpauses is incremented. Here's what I see, with the value of beamerpauses (in italics) evaluated at lots of occasions. First, the actual code I ran (beamerpauses coloured to make it stand out). {\color{green}\thebeamerpauses} ...

The <handout:O> syntax tells beamer to remove something from a slide in the handout version. It can also be used to tell beamer to put things on different slides in the handout version. Thus saying <handout:2> says "make sure that there is a second slide in the handout version and put this on it.". Thus: \documentclass[handout]{beamer} ...

Here is another solution using \setbeamercovered{invisible} and \pause \documentclass{beamer} \usepackage{tikz} \usetikzlibrary{positioning} \begin{document} \begin{frame}{Linearity} \setbeamercovered{invisible} \begin{center} \begin{tikzpicture} \node(Ctx){$E$};\pause \node[above left=0.5cm and 0.1cm of Ctx] (gamma) {$\Gamma$};\pause ...

You might be interested in the cancel package. Or something similar can be implemented in TikZ. \documentclass{article} \usepackage{tikz} \newcommand{\strikeout}[2][]{% % usage: \strikeout[bar]{foo} strikes out foo and superimposes bar % \strikeout{foo} strikes out foo. \begin{tikzpicture}[baseline=0] \node[anchor=base,inner ...

Following up the discussion of diabonas answer, here my suggestion. The idea to use phantom boxes seems the way to go. Here the two alternatives are boxed so that they can be measured. The code could be improved to detect the mode (text, math, display math, etc.) by itself and avoid the re-boxing which happens in the phantom commands. \documentclass{beamer} ...

Using atbegshi guarantees that the text block will not be modified in any way, as it acts by "overlaying", so to speak. \documentclass[a4paper]{article} \usepackage{atbegshi,picture} \usepackage{lipsum} \AtBeginShipout{\AtBeginShipoutUpperLeft{% \put(\dimexpr\paperwidth-1cm\relax,-1.5cm){\makebox[0pt][r]{\framebox{Copyright DTV}}}% }} \begin{document} ...

You can add a new plot with a different plot type by using \addplot [<plot type>] ...;. If you want to add a line plot to a column plot, you would use \addplot [sharp plot] ...;. If you want to keep the current color cycle uninterrupted, add a + in front of the options: \addplot +[sharp plot] ...; To calculate the cumulated sums automatically, you ...

Obligatory Unicode answer: With XeLaTeX or LuaLaTeX with the unicode-math package, you can use ⟃ (i.e. U+27C3 OPEN SUBSET) directly (or use the alias \subsetcirc). There is also ⪽ (U+2ABD SUBSET WITH DOT; \subsetdot) and ⫏ (U+2ACF CLOSED SUBSET; \csub). Unicode doesn't seem to contain a subset symbol with a bullet inside.

If you just want the boundaries overlaid on the actual pages, independently of other packages, \usepackage{showframe}
