[Tex/LaTex] How to draw frame with rounded corners around box

boxesframedrounded-corners

Is it possible to simply draw a frame around a box which has rounded corners, and be able to control frame width, frame color, frame radius, box background colour
(preferably without having to use the complex TikZ package)

eg. (this produces a framed box, but without the required rounded corners)

\documentclass{article}
\usepackage{graphicx}
\usepackage{color}
\usepackage{fancybox}
\begin{document}

\fboxsep=3pt
\fboxrule=2pt
\def\bordercolor{red}
\def\backgroundcolor{white}
\cornersize{0.9}
\fcolorbox{\bordercolor}{\backgroundcolor} {Here is some text}%

\end{document}

Here's a method that doesn't require loading TikZ explicitly. (Although mdframed uses tikz behind the scenes. This is, however, the package for framing boxes.

\documentclass{article}
\usepackage[framemethod=TikZ]{mdframed}
\usepackage{lipsum}
\begin{document}
\begin{mdframed}[roundcorner=10pt]
  \lipsum[1]
\end{mdframed}
\end{document}

If you don't even want to use TikZ as a backend, you could use PSTricks:

\documentclass{article}
\usepackage[framemethod=PStricks]{mdframed}
\usepackage{lipsum}
\begin{document}
\begin{mdframed}[roundcorner=10pt]
  \lipsum[1]
\end{mdframed}
\end{document}

[Note this doesn't seem to be working for me at the moment.]

Have a look at the mdframed package:

\documentclass{article}
\usepackage[framemethod=tikz]{mdframed}
\usepackage{lipsum}

\definecolor{mycolor}{rgb}{0.122, 0.435, 0.698}

\newmdenv[innerlinewidth=0.5pt, roundcorner=4pt,linecolor=mycolor,innerleftmargin=6pt,
innerrightmargin=6pt,innertopmargin=6pt,innerbottommargin=6pt]{mybox}

\begin{document}

\lipsum[2]
\begin{mybox}
\lipsum[4]
\end{mybox}
\lipsum[2]

\end{document}

A solution with hf-tikz (requires two compilation runs):

\documentclass[dvipsnames]{article}
\usepackage{amsmath}
\usepackage[customcolors]{hf-tikz}
\definecolor{My}{RGB}{0,31,63}
\definecolor{MyConst}{RGB}{128,128,128}
\definecolor{MyFunc}{RGB}{0,75,107}
\definecolor{MyIndep}{RGB}{127,55,0}
\definecolor{MySubst}{RGB}{250,230,230}
\newcommand{\const}[1]{{\color{MyConst}\mathrm{#1}}}     % normal constant
\newcommand{\uconst}[1]{\mathrm{#1}}                     % universal mathematical constant
\newcommand{\var}[1]{{\color{MyIndep}#1}}                % independent variable
\newcommand{\subst}[1]{{\colorbox{MySubst}#1}}           % substitution

\hfsetfillcolor{Lavender!50}
\hfsetbordercolor{white}

\begin{document}
\[
\color{My}
{\color{MyFunc}\Psi} =
\const{\Psi_{_0}}\;
\uconst{e}^{\uconst{i} \left(   
    \tikzmarkin{a}(0.01,-0.175)(-0.015,0.3)\frac{p}{\const{\hbar}}\tikzmarkend{a}
    \var{x} - \tikzmarkin{b}(0.01,-0.175)(-0.015,0.3)\frac{E}{\const{\hbar}}\tikzmarkend{b}\var{t} \right) }
\]
\end{document}

The result:

enter image description here

Remarks:

it is better to use \[ \] rather than $$ $$;
the package allows you to not set in math mode the text inside a \colorbox: one just have to declare where the delimiters of the box should be positioned.

From version 0.3 of the package, things are a bit more user-friendly as shown in hf-tikz doesn't box around equation. The above code can be written thanks to styles as:

\documentclass[dvipsnames]{article}
\usepackage{amsmath}
\usepackage[customcolors]{hf-tikz}
\definecolor{My}{RGB}{0,31,63}
\definecolor{MyConst}{RGB}{128,128,128}
\definecolor{MyFunc}{RGB}{0,75,107}
\definecolor{MyIndep}{RGB}{127,55,0}
\definecolor{MySubst}{RGB}{250,230,230}
\newcommand{\const}[1]{{\color{MyConst}\mathrm{#1}}}     % normal constant
\newcommand{\uconst}[1]{\mathrm{#1}}                     % universal mathematical constant
\newcommand{\var}[1]{{\color{MyIndep}#1}}                % independent variable
\newcommand{\subst}[1]{{\colorbox{MySubst}#1}}           % substitution

% available from version 0.3
\tikzset{offset def/.style={
    above left offset={-0.015,0.3},
    below right offset={0.01,-0.175},
  },
  hl/.style={
    offset def,
    set fill color=Lavender!50,
    set border color=white,
  }
}

\begin{document}
\[
\color{My}
{\color{MyFunc}\Psi} =
\const{\Psi_{_0}}\;
\uconst{e}^{\uconst{i} \left(   
    \tikzmarkin[hl]{a}\frac{p}{\const{\hbar}}\tikzmarkend{a}
    \var{x} - \tikzmarkin[hl]{b}\frac{E}{\const{\hbar}}\tikzmarkend{b}\var{t} \right) }
\]
\end{document}

Procedure to get .png output

After reading the comments below, here is a way to get a .png. The standalone class here really helps since it has a png class option.

Save as test.tex:

\documentclass[dvipsnames,png, border=2pt]{standalone}
\usepackage{amsmath}
\usepackage[customcolors]{hf-tikz}
\definecolor{My}{RGB}{0,31,63}
\definecolor{MyConst}{RGB}{128,128,128}
\definecolor{MyFunc}{RGB}{0,75,107}
\definecolor{MyIndep}{RGB}{127,55,0}
\definecolor{MySubst}{RGB}{250,230,230}
\newcommand{\const}[1]{{\color{MyConst}\mathrm{#1}}}     % normal constant
\newcommand{\uconst}[1]{\mathrm{#1}}                     % universal mathematical constant
\newcommand{\var}[1]{{\color{MyIndep}#1}}                % independent variable
\newcommand{\subst}[1]{{\colorbox{MySubst}#1}}           % substitution

\hfsetfillcolor{Lavender!50}
\hfsetbordercolor{white}

\begin{document}
$
\color{My}
{\color{MyFunc}\Psi} =
\const{\Psi_{_0}}\;
\uconst{e}^{\uconst{i} \left(   
    \tikzmarkin{a}(0.01,-0.175)(-0.015,0.3)\frac{p}{\const{\hbar}}\tikzmarkend{a}
    \var{x} - \tikzmarkin{b}(0.01,-0.175)(-0.015,0.3)\frac{E}{\const{\hbar}}\tikzmarkend{b}\var{t} \right) }
$
\end{document}

and compile with:

pdflatex -shell-escape test.tex

This will create

test.pdf
test.png

perfectly cropped.
