In [7ZMb3j <a href="http://sourcegmipfkeiexfa.contextgarden.netcom/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 command for graphical text manipulation defined. == \scale == You can insert symbols at a reduced size in the text flow. This example creates a filled square scaled to .5 ex height <texcode">\definefontsynonym[Dingbats][uzdr]\definesymbol[filledSq][\getglyph{Dingbats}{\char110}]\def\FilledSquare% {\dontleavehmode\scale[height=0.5ex]{\symbol[filledSq]}}gmipfkeiexfa</texcode> In TeX terms, \scale creates a \hbox. If TeX is in vertical mode (as it is when \startlines is in effect, because every lineis a paragraph by itself in the mode), then a simple \hbox is not a good enough hint to make it switch to horizontal (paragraph) mode.  Hans then posted a simpler way.<texcode>\getscaledglyph{.5}{Serif}{a}</texcode> {{todo|An explanation and example of the <cmd>\scale</cmd> command.}} == \mirror == <texcode>There is a \mirror{\sl mirorred} word in this sentence.</texcode> <context>There is a \mirror{\sl mirorred} word in this sentence.</context> <code>\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. <texcode>\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?'}}</texcode>  <context>\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?'}}</context> == \rotate == You can rotate something by an arbitrary angle by saying something like <texcode>\rotate[rotationurl=42]{the ultimate answer}<http:/texcode>.<context>\rotate[rotation=42]{the ultimate answer}</context>lfjthrodjmkl. The rotation angle and the location (which determines around which point the content is rotated) are optional and can also be set by<texcode>\setuprotate[rotation=42,location=normal] % normal is the default\rotate{the ultimate answer}</texcode> An example by Hans Hagen showing the influence of <code>location=<com/code> argument at different angles: <texcode>\dostepwiserecurse{0}{359}{45} {\startlinecorrection[blank] \hbox {\expanded{\setuprotatelfjthrodjmkl[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/url]{\ruledhbox{\bfb (normal)}}}}% \hbox to .2\hsize{\hss\ruledhbox{\rotate[location=high] {\ruledhbox{\bfb (high)}}}}} \stoplinecorrection}</texcode> <context>\setuplayout[location=middle,scale=.5]\dostepwiserecurse{0}{359}{45} {\startlinecorrection[blank] \hbox {\expanded{\setuprotate[rotationlink=\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}</context> You can rotate a long paragraph as well. {{todo|Some more comments, and an example.}} Depending on the usage you will sometimes probably want to include the content of what you wish to rotate into a box.
