In [http://source.contextgarden.net/tex/context/base/core-mis.mkii core-mis.mkii] ([http://source.contextgarden.net/tex/context/base/core-mis.mkiv core-mis.mkiv] for MkIV) there are some handy You can use the commands for graphical text manipulation defined, but also for graphics or other “building blocks”.

== \scale =Scaling=

You The {{cmd|scale}} command is all-purpose, you can insert symbols at scale by factors or to a reduced defined size in the text flow. This example creates a filled square scaled to .5 ex height

<texcode>\definefontsynonym[Dingbats][uzdr]\definesymbol[filledSq][\getglyphAs a special case, you can insert symbols at a reduced size in the text flow using {Dingbats{cmd|getscaledglyph}{\char110}]\def\FilledSquare% {\dontleavehmode\scale[height=0.5ex]{\symbol[filledSq]}}</texcode>

In TeX terms, \scale creates a <context source=yes>\hboxgetscaledglyph{. If TeX is in vertical mode (as it is when \startlines is in effect, because every lineis 5}{Serif}{a paragraph by itself in the mode), then } a simple \hbox is not getscaledglyph{2}{Serif}{a good enough hint to make it switch to horizontal (paragraph) }mode. </context>

<code>\{{cmd|mirror</code> }} makes a <code>\hbox</code> and mirrors the contents. If you want to have a longer paragraph mirrored, you have to make a <code>\vbox</code> manually.
