Scaling Rotating Mirroring Clipping (view source)

< [[Graphics]] | [[Using_Graphics]] > In [http://source.contextgarden.net/tex/context/base/core-mis.mkii core-mis.mkii] ([http://source.contextgarden.net/tex /context/base/core-mis.texmkiv core-mis.mkiv] for MkIV) there are some handy command commands for graphical text manipulation defined. This page’s title is misleading, since you can use the commands also for graphics and other “building blocks”.

<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.
\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
You can rotate something by an arbitrary angle by saying something like
<texcodecontext source=yes>
\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
<texcodecontext source=yes>
\setuprotate[rotation=42,location=normal] % normal is the default
\rotate{the ultimate answer}
</texcodecontext> === location parameter ===
An example by Hans Hagen showing the influence of <code>location=</code> argument at different angles:
<texcodecontext source=yes>
\dostepwiserecurse{0}{359}{45}
{\startlinecorrection[blank]
\hbox to .2\hsize{\hss\ruledhbox{\rotate[location=high] {\ruledhbox{\bfb (high)}}}}}
\stoplinecorrection}
</texcodecontext>
You can rotate a long paragraph as well.
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:
<texcodecontext source=yes>
\setuplayout[width=3cm]
\setuprotate[rotation=180,location=broad]
a\rotate{e}i\par
a\rotate{\hbox{e}}i
</context>
=== 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</cmd> command can help:
<texcode>
\rotate[rotation=\doifoddpageelse{90}{270}]{\externalfigure[cow]}
</texcode>
This example is by Wolfgang, from [http://www.ntg.nl/pipermail/ntg-context/2011/059834.html the thread starting here]. The thread contains other solutions to the problem. == \clip == You can adjust the size of an element by cropping/clipping its borders: <contextsource="yes">\setuplayoutclip[widthnx=3,ny=3,x=1,y=3cm1]{\setuprotateexternalfigure[rotation=180,location=broadcow]}</context>
