I am working on a presentation in beamer and would like to put a logo in the background of the title page with a gradient fade-out effect, similar to the image below. The logo is in PDF format and is in full-shape.

  • You can achieve a similar effect on your personal logo in application such as Illutrator of Inkscape. This is not done directly within beamer. – pluton Nov 27 '13 at 08:42

    Sure, though I am under impression that it can also be done using TikZ quite simply. – Ali Nov 27 '13 at 08:45

With WriteLaTeX's frog.jpg, also in https://www.writelatex.com/542861kyqykv

\documentclass{beamer}
\usetheme{Warsaw}
\usepackage{tikz}
\usetikzlibrary{fadings}


\setbeamertemplate{background}{%
\begin{tikzpicture}
\path (0,0) rectangle (\paperwidth,\paperheight);
\node[scope fading=west,inner sep=0pt,outer sep=0pt,anchor=north east] at(\paperwidth,\paperheight) {\includegraphics[height=\paperheight]{frog.jpg}};
\end{tikzpicture}
}

  • Your answer reminds of that question: http://tex.stackexchange.com/questions/112538/can-fuzzy-borders-be-added-to-external-pictures-programmatically. Would there be a way of superimposing multiple facings in different directions? – jub0bs Nov 27 '13 at 10:07
  • @Jubobs Should be possible within a transparency group. – percusse Nov 27 '13 at 15:14
  • How do you do the same, but with a fading to the South or, even better South East? With me the image becomes all white when you replace "west" by "south" – Neige Jul 28 '18 at 22:45
  • @percusse, How would you put it only first page? – Alexandre Loures Feb 06 '19 at 23:56
