[Tex/LaTex] How to achieve this Beamer style

beamercolorheader-footerlogos

I think the attached slide used the following beamer settings:

\usetheme[]{Frankfurt}   % or berlin
\usecolortheme{beaver}  % red color

However, I have several questions:

How to customize the foot-line to: Topic + Author (email) + Institute + Page Number?
How to make the background colour of the logo matching the beamer colour theme?

My institute logo is a JPG file and the background colour is white. If the beamer theme colour is NOT white, then an area of white colour will appear in the title.

I think SVG file will solve this problem, but latex does not support this format. If we convert the SVG file to jpg/png format, the white background colour will appear again! How to figure this out?

Update: including logo in pdf format solves the problem 2.

I defined a footline template inspired by the one used by the infolines outer theme, containing the required fields. The new template is called myfootline and you activate it by using

\setbeamertemplate{footline}[myfootline]

The code:

\documentclass{beamer}
\usetheme[]{Berlin}
\usecolortheme{beaver}  % red color

\makeatletter
\defbeamertemplate*{footline}{myfootline}
{
  \leavevmode%
  \hbox{%
  \begin{beamercolorbox}[wd=.333333\paperwidth,ht=2.25ex,dp=1ex,center]{title in head/foot}%
    \usebeamerfont{title in head/foot}\insertshorttitle
  \end{beamercolorbox}%
  \begin{beamercolorbox}[wd=.333333\paperwidth,ht=2.25ex,dp=1ex,center]{title in head/foot}%
    \usebeamerfont{author in head/foot}\insertshortauthor\expandafter\beamer@ifempty\expandafter{\beamer@shortinstitute}{}{~~\insertshortinstitute}
  \end{beamercolorbox}%
  \begin{beamercolorbox}[wd=.333333\paperwidth,ht=2.25ex,dp=1ex,right]{title in head/foot}%
    \usebeamerfont{date in head/foot}\insertshortdate{}\hspace*{2em}
    \insertframenumber{} / \inserttotalframenumber\hspace*{2ex} 
  \end{beamercolorbox}}%
  \vskip0pt%
}
\makeatother
\setbeamertemplate{footline}[myfootline]

\title{The title}
\author[The author (author@tex.sx)]{The author \\\href{mailto:author@tex.sx}{author@tex.sx}}
\institute{The Institution}

\begin{document}

\begin{frame}
\maketitle
\end{frame}

\section{A test section}
\begin{frame}
\frametitle{A test frame title}
test
\end{frame}

\end{document}

And a close-up to the footline:

Since the footline now has too much information, perhaps you'll need to adjust the width of the beamercolorboxes used in the template.

As for question 2, I think it is not really on-topic here since it concerns a problem related to specifics of image formats manipulation and not to (La)TeX itself. However, in our sister site Graphic Design you can find some answers to this question; see, for example Add transparency to an existing PNG or Making the background of an image transparent.

[Tex/LaTex] Change background color in metapost

Here's a receipe for drawing an image whose dimensions aren't known in advance on a background that scales to the image's final bounding box:

Draw the image.
Save the image in a picture variable.
Measure the picture's bounding box.
Draw the background.
Re-draw the original image on top of the background.

Here's an example followed by some random notes:


beginfig(1);
  %
  % Draw random picture.
  %
  pair p,q;
  for i = 1 upto 20:
    p := (uniformdeviate 200, uniformdeviate 200);
    q := (uniformdeviate 200, uniformdeviate 200);
    draw p--q withpen pencircle scaled 2 withcolor red;
  endfor
  %
  % Solution starts here.
  %
  % Save picture in variable pic for later reference.
  picture pic;
  pic := currentpicture;
  % Clear currentpicture to avoid outputting the picture twice.
  currentpicture := nullpicture;
  % Fill a rectangle with pic's bounding box dimensions (plus
  % bboxmargin) with desired background colour.
%  interim bboxmargin := 0;
  fill bbox pic withcolor blue;
  % Draw original picture on top of background.
  draw pic;
endfig;
end

Saving an image in a picture variable can either be done by storing currentpicture in a picture variable or via the image command (see the MetaPost manual for more information). If the currentpicture method is used, like in the example, make sure to clear currentpicture before drawing the background. Otherwise the image is output twice, the first copy being hidden behind the background, bloating the output file.

The bbox command returns a rectangular path corresponding to the bounding box of the picture argument plus a small amount determined by the internal variable bboxmargin (2bp by default).

Internal variables can be modified locally to the current group using the interim statement. That is, if you wrap an assignment to an internal variable in begingroup ... endgroup; the variable's value is restored after the group. Note, beginfig() just starts a group that ends at the corresponding endfig.

[Tex/LaTex] Colour themes in beamer not working for lemma/theorem/definition environments

The Antibes theme calls the orchid color theme. This sets the colors for the block environments (as seen in the beamercolorthemeorchid.sty), but the beaver color theme does not set those colors. So you have to do it by hand. The lines you could add (and edit to your liking) in your themes sections are

\setbeamercolor{block title}{use=structure,fg=white,bg=structure.fg!75!black}
\setbeamercolor{block title alerted}{use=alerted text,fg=white,bg=alerted text.fg!75!black}
\setbeamercolor{block title example}{use=example text,fg=white,bg=example text.fg!75!black}

\setbeamercolor{block body}{parent=normal text,use=block title,bg=block title.bg!10!bg}
\setbeamercolor{block body alerted}{parent=normal text,use=block title alerted,bg=block title alerted.bg!10!bg}
\setbeamercolor{block body example}{parent=normal text,use=block title example,bg=block title example.bg!10!bg}

and the beamercolorthemebeaver.sty might help you to pick the matching colors.

You are probably using the standard block most of the time. Here we see that the orchid theme uses the structure color, which is set by\setbeamercolor{structure}{fg=beamer@blendedblue} in the default color theme.

Long story short: Maybe you can just set the structure color to something that matches the theme. For example

 \setbeamercolor{structure}{fg=darkred}

Note that darkred is a color set within the beaver color theme.

This gives you slides like this:

And if you'd rather have a gray background for the body of the block, add something like:

\setbeamercolor{block body}{bg=gray!10!white}

to get this result:
