Changes

== Combinations are ConTeXt's way to align several pictures (preferrably at same size):==

<pretexcode>\startcombination[x*y]%% x=columns, y=rows

</pretexcode> or using the newer interface: <texcode>\startcombination [nx=3, ny=2] %% 3 columns, 2 rows \startcontent something \stopcontent \startcaption caption \stopcaption \startcontent something \stopcontent \startcaption caption \stopcaption \startcontent something \stopcontent \startcaption caption \stopcaption \startcontent something \stopcontent \startcaption caption \stopcaption \startcontent something \stopcontent \startcaption caption \stopcaption \startcontent something \stopcontent \startcaption caption \stopcaption\stopcombination </texcode> 

You must provide one "figure something" (e.g. an <tt>\{{cmd|externalfigure</tt>}}) and a caption for every "cell". The sample, from the manual, shows how to define a caption for the whole group and use it as float (see [[Floating Objects]]): <context source=yes>\useMPlibrary [dum] %% sample images \startplacefigure [title=An example of a combination] \startcombination [nx=3, ny=2] \startcontent \externalfigure [dummy] \stopcontent \startcaption a \stopcaption \startcontent \externalfigure [dummy] \stopcontent \startcaption b \stopcaption \startcontent \externalfigure [dummy] \stopcontent \startcaption c \stopcaption \startcontent \externalfigure [dummy] \stopcontent \startcaption d \stopcaption \startcontent \externalfigure [dummy] \stopcontent \startcaption e \stopcaption \startcontent \externalfigure [dummy] \stopcontent \startcaption f \stopcaption \stopcombination\stopplacefigure</context> === Image Width === The image widths aren’t calculated automatically: <context source="yes">\startcombination[3*1] {\externalfigure[cow]}{cow} {\externalfigure[mill]}{mill} {\externalfigure[hacker]}{hacker}\stopcombination</context> You could define them on your own: <texcode>\startcombination[3*1] {\externalfigure[cow] [width=.3\textwidth]}{cow} {\externalfigure[mill] [width=.3\textwidth]}{mill} {\externalfigure[hacker][width=.3\textwidth]}{hacker}\stopcombination</texcode> But that’s ugly and tedious. Hans did it for you in {{src|grph-inc.mkxl}}: <texcode>\definemeasure[combination][ (\textwidth -\effectiveleftskip -\effectiverightskip -\numexpr\combinationparameter\nx-\plusone\relax\dimexpr\combinationparameter\distance\relax )/\combinationparameter]</texcode> So you can say: <texcode>\startcombination[3*1] {\externalfigure[cow] [width=\measure{combination}]}{cow} {\externalfigure[mill] [width=\measure{combination}]}{mill} {\externalfigure[hacker][width=\measure{combination}]}{hacker}\stopcombination</texcode> But that’s still tedious. With the power of {{cmd|defineexternalfigure}}: <texcode>\defineexternalfigure[combination][width=\measure{combination}]</texcode>(That’s predefined, no need to copy!)

The sample from the manual:<precontext source="yes">\placefigure[here] % placement[fig:combinations] % reference{An example of combination} % caption for whole group{\startcombination[3*21] % 3 columns, 2 rows {\externalfigure[lb00220cow]} {a} {\externalfigure [lb00221combination]} {bcow} % picture and caption for two figures in first row {\externalfigure[lb00222mill]} {c} {\externalfigure [lb00223combination]} {dmill} {\externalfigure[lb00225hacker]} {e} {\externalfigure[lb00226combination]} {fhacker}

</context> Beautiful. ;) == Floatcombinations == When combination contain floats, the command {{cmd|startfloatcombination}} is used. Here an example using float combinations as well as subfloatnumbering that creates subfigures sharing a mutual figure prefix and an individual subfigure designator (e.g. figure 1a), figure 1b, etc.). <context source=yes>\useMPlibrary [dum] \startplacefigure [location=none] \startfloatcombination [nx=2] \startplacefigure [title=Left, reference=ref:left, group=one, groupsuffix=a] \externalfigure \stopplacefigure \startplacefigure [title=Right, reference=ref:right, group=one, groupsuffix=b] \externalfigure \stopplacefigure \stopfloatcombination\stopplacefigure See \in{image} % whole combination [ref:right] (right) and \in braces of placefigure{image}[ref:left] (left).</precontext>shows how to define == Setup == There is the {{cmd|setupcombinations}} command. == Referencing == To reference a subfigure you can provide the subfigure's caption for as a second parameter to the whole group and use it as float (see {{cmd|in}} command. To reference the subfigure with the caption d you would write: <texcode>\in{figure}{d}[fig:combinations]</texcode> This would produce something like 'figure 2.4d'. The content of the second parameter simply gets appended to the end of the figure's reference-number, thus the example above would still work even if the caption would be 'd) An awesome subfigure'. == See also ==[[Floating_Objects#Subfloats]], {{cmd|startfloatcombination}}, {{cmd|startsubfloatnumbering}} [[Floating ObjectsCategory:Graphics]]).
