# How to achieve specific results

## Preventing hyphenation

One can prevent hyphenation inside a frame by passing nothypenated option to align. It is also a good idea to add verytolerant and strectch options.

\startcombination[2*2]
{\framed
[width=5cm,
align={flushleft}]
{\input ward \endgraf}}
{flushleft}
{\framed
[width=5cm,
align={flushleft,nothyphenated,verytolerant}] % maybe also stretch
{\input ward \endgraf}}
{flushleft,\crlf nothypenated, \crlf verytolerant}
{\framed
[width=5cm,
align={flushright,nothyphenated,verytolerant}] % maybe also stretch
{\input ward \endgraf}}
{flushright,\crlf nothypenated, \crlf verytolerant}
{\framed
[width=5cm,
align={width,nothyphenated,verytolerant}] % maybe also stretch
{\input ward \endgraf}}
{width,\crlf nothypenated, \crlf verytolerant}
\stopcombination


## Specify the width no longer than needed

I want to specify the maximum width of a frame. If the size of the box is smaller than the maximum width, I want a tight box. This can be done using the autowidth=force option to framed.

\defineframed
[tightframed][width=5cm,autowidth=force,align=middle]

\tightframed{Small}

\tightframed{A really really long line that is split at 5cm}



## Ruled Frames

\framed allows you to specify specific edges to be ruled. As an alternative to frame=on (the default), one can specify topframe=on, etc. Note that, as the default is to draw a complete frame, it is necessary to either specify the state (on/off) for all four edges or include the keyword frame=off.

\framed[frame=off,topframe=on,leftframe=on]{A fancy title}


The thickness of the frame rule can be specified using rulethickness=

\framed[frame=off,leftframe=on,rulethickness=2pt]{\tfa\bf A fancy title}


## Rounded Corners

\framed allows you to have round corners with corner=round. There are also other possibilities if you want round corners but not at all places by giving an appropriate number to corner=.... This example is taken from core-rul.tex and each frame is typeset using

 \framed[corner=....,frame=on]{...}


• You can only fill the frame with a background color if the corner shape is closed. Otherwise, the backgroundcolor option will be silently ignored.

## Coloring frame background and framed text

First you have to turn on colors with \setupcolors[state=start]. Then you can define the background and foreground (=text) colors:

\framed[background=color,backgroundcolor=....,foreground=color,foregroundcolor=...]{...}

If you want to make the frame itself disappear, add a frame=off to the setups.

For filling frames with offset you have to add options frameoffset=..., backgroundoffset=...

See the Colors section for more information on available colors and color usage.

## Shaded background for part of a displayed equation

To highlight part of a formula, you can give it a gray background using \framed:

\setupcolors[state=start]
\def\graymath{\mframed[frame=off,
background=color,
backgroundcolor=gray,
backgroundoffset=3pt]}

\startformula
\ln (1+x) =\, \graymath{x - {x^2\over2}} \,+ {x^3\over3}-\cdots.
\stopformula


The \, add a tiny bit of space to prevent the gray background from crowding the equals and plus sign.

## Inline Frames

The command \inframed, similar to \framed, differs in the definition of the baseline:

\framed[frame=off,width=10em,align=width]{%
Notice the difference between
\framed{framed} and \inframed{inframed},
especially considering its effect on linespacing...
