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 scale by factors or to a defined size. As a special case, you can insert symbols at a reduced size in the text flowusing {{cmd|getscaledglyph}}.

= Mirroring =<texcodecontext source=yes>There is a \mirror{\sl mirorred} word in this sentence.</texcode> <context>There is a \mirror{\sl mirorredword} word in this sentence.

<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.

<texcodecontext source=yes>

once or twice she had peeped into the book her sister was reading, but it had no pictures or conversations in it, `\quote{and what is the use of a book,' } thought Alice `\quote{without pictures or conversation?'}}}</texcodecontext>

<context>\mirrorYou can {\vbox{Alice was beginning to get very tired of sitting by her sister on the bank, and of having nothing to do: once or twice she had peeped into the book her sister was reading, but it had no pictures or conversations in it, `and what is the use of a book,' thought Alice `without pictures or conversation?'cmd|rotate}}</context> == \rotate ==something by an arbitrary angle like

An example by Hans Hagen showing the <context source=yes>\ss Next generation L\rotate{m}\rotate{m}TSP\mirror{3}Al\rotate[rotation=270,location=high]{v}?</context> You can rotate a long paragraph as well. ==Location parameter== The influence of <code>location=</code> argument at different angles:

You can The following code shows how the location parameter influences rotation with a frame: <texcode>\setupbodyfont[sans, 30pt]\setuppagenumbering[location=,]\showframe \starttext \topskip4cm \dostepwiserecurse{0}{360}{10}{\doloopoverlist{normal,default,depth,fit,broad,high,middle}{\ruledhbox{\rotate[rotation=\recurselevel, location=\recursestring]{%\framed [width=\textheight, height=\textwidth, rulethickness=5pt, depth=0cm, foregroundstyle=\bfd] {\recursestring, \recurselevel°} } } }}\stoptext</texcode> or, even nicer: <context source="yes">\useMPlibrary[dum]\setupexternalfigures[width=4em,height=3em,frame=on,]\dostepwiserecurse{0}{359}{45}{{\bf\recurselevel˚}\quad \doloopoverlist{normal,depth,fit,broad,high,middle}{ \dontleavehmode\ruledhbox{% \rotate [rotation=\recurselevel, location=\recursestring]{% \externalfigure[\recursestring] }% }% }\par}</context> ==In a long paragraph as well.box==

== Page dependent landscape figures== Sometimes, in a double-sided portrait document, you may wish to rotate a landscape figure so that the top is towards the spine of the book – no matter whether it’s on an odd or even page. In this case the {{cmd|doifoddpageelse}} command can help: <texcode>\clip =rotate[rotation=\doifoddpageelse{90}{270}]{\externalfigure[cow]}</texcode> (This example is not just about text manipulationby Wolfgang, from [http://www.ntg.nl/pipermail/ntg-context/2011/059834.html the thread starting here].)The thread contains other solutions to the problem. =Clipping= You can adjust the size of an element by cropping/clipping its borders:

\clip[ny=3,y=1]{\color[yellow]{\MyLogo}}\clip[ny=3,y=2]{\color[orange]{\MyLogo}}\clip[ny=3,y=3]{\color[red]{\MyLogo}}</context> And here’s how to cut out a piece by measures (see also {{cmd|setupclipping}} and {{cmd|clip}}): <context source="yes">\clip[width=3cm, height=1cm, hoffset=1cm, voffset=5mm]{\externalfigure[cow][width=5cm]}
