You can use the commands for text, but also for graphics or other “building blocks”.
Contents
Scaling
You can insert symbols at a reduced size in the text flow.
\getscaledglyph{.5}{Serif}{a} a \getscaledglyph{2}{Serif}{a}
Mirroring
There is a \mirror{\sl mirorred} {\sl word} in this sentence.
\mirror makes a \hbox and mirrors the contents. If you want to have a longer paragraph mirrored, you have to make a \vbox manually.
\mirror{\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?'}}
Rotating
You can rotate something by an arbitrary angle by saying something like
\rotate[rotation=42]{the ultimate answer}
The rotation angle and the location (which determines around which point the content is rotated) are optional and can also be set by
\setuprotate[rotation=42,location=normal] % normal is the default \rotate{the ultimate answer}
Location parameter
An example by Hans Hagen showing the influence of location= argument at different angles:
\dostepwiserecurse{0}{359}{45} {\startlinecorrection[blank] \hbox {\expanded{\setuprotate[rotation=\recurselevel]}% \traceboxplacementtrue \hbox to .2\hsize{\hss\ruledhbox{\rotate[location=depth] {\ruledhbox{\bfb (depth)}}}}% \hbox to .2\hsize{\hss\ruledhbox{\rotate[location=fit] {\ruledhbox{\bfb (fit)}}}}% \hbox to .2\hsize{\hss\ruledhbox{\rotate[location=broad] {\ruledhbox{\bfb (broad)}}}}% \hbox to .2\hsize{\hss\ruledhbox{\rotate[location=normal]{\ruledhbox{\bfb (normal)}}}}% \hbox to .2\hsize{\hss\ruledhbox{\rotate[location=high] {\ruledhbox{\bfb (high)}}}}} \stoplinecorrection}
You can rotate a long paragraph as well.
In a box
Depending on the usage you will sometimes probably want to include the content of what you wish to rotate into a box. Compare the following two examples:
\setuplayout[width=3cm] \setuprotate[rotation=180,location=broad] a\rotate{e}i\par a\rotate{\hbox{e}}i
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 \doifoddpageelse command can help:
\rotate[rotation=\doifoddpageelse{90}{270}]{\externalfigure[cow]}
This example is by Wolfgang, from 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[nx=3,ny=3,x=1,y=1]{\externalfigure[cow]}
\setupcolors[state=start] \definedfont[SansBold at 20mm] \baselineskip 0pt % switch off the space between the stripes \lineskip 0pt \def\MyLogo{\vbox{\hbox{\CONTEXT}\null}} % null is necessary for the whole bounding box \clip[ny=3,y=1]{\color[yellow]\MyLogo} \clip[ny=3,y=2]{\color[orange]\MyLogo} \clip[ny=3,y=3]{\color[red]\MyLogo}
see also \setupclipping and \clip

In core-mis.mkii (for MkII), there are some handy commands for graphical text manipulation defined.
