float combinations

float combinations

[Robert Blackstone]

Dear all,

I would like to have in my document floats, i.c. musical examples, that basically have the same  number, for example, Ex. 3a and Ex. 3b, with text in between and possibly not even on the same page. 

It seems that it can be done (Wiki-page Command/setupfloatsplitting) but I have no idea how to to accomplish it for figures.

Alternatively can one create a combination of two figures but separate the two elements spatially? And if so, how?
Thanks in advance for any advice.

Best regards,

Robert Blackstone

Of course, thank you!

However, there is another problem with this second solution as it
shares the same counter with figure, rather than its own. This can be
corrected by *not* inheriting from [figure], as in
    \definefloat [figureitem] [figureitems]
Still, there needs to be some mechanism to automatically reset the
counter, for example via a "way=" keyword,...

Hans will surely be dreaming up a combinationitem scheme...

Ah, more undocumented features... :)

\definefloat  [figureitem] [figureitems] [figure]
\setupcaption [figureitem] [numberconversion=character]
\startplacefigure [title=Cows]
     \startfloatcombination[2*2]
         \startplacefigureitem [title=alpha] \externalfigure [cow] [width=1cm] \stopplacefigureitem
         \startplacefigureitem [title=beta]  \externalfigure [cow] [width=2cm] \stopplacefigureitem
         \startplacefigureitem [title=gamma] \externalfigure [cow] [width=3cm] \stopplacefigureitem
         \startplacefigureitem [title=delta] \externalfigure [cow] [width=4cm] \stopplacefigureitem
    \stopfloatcombination
\stopplacefigure

Two problems, though:
1. I tried "label=" in \setupcaption to suppress "Figure ". This does not work,
   and looking at the source I do not see how to do this...
2. Missing is some way to reset the figureitem counter automatically with each \startfloatcombination.
   It looks as if it could be a nice feature to add new keywords like "before=" and "after=".
   Maybe "beforeall=" and "afterall=", "beforefirst=" and "afterlast=", ... 

I suppose that the above brings little advantage over the \definelabel solution previously suggested.

Thank you, Marco, and Alan, for  your suggestions.

As I wrote, wherever possible I use combinations for related examples, and they only give problems when the examples are too large to fit on the same page. 
The solution with itemize does not help here. With small enough figures the results seems not too different from that with Combinations. With large figures stacked vertically the lower one still gets cut off (and with it also the caption when it is placed underneath the figure). If somehow a pagebreak could be inserted between the two items, then this solution would probably work. 
But I have no idea how to achieve this. Inserting \page between " \startitem A cow\stopitem"   and  "\startitem A mill \stopitem" changes nothing.

Best regards
Robert

Thank you very much, Hans. This is really perfect for my purpose.

sure, but then it's nice to have it as option of the combination command

anyway, there's also (we've always needed such things in projects):

\starttext

\startplacefigure[location={here,none}]
     \startfloatcombination[2*2]
         \placefigure{alpha}{\externalfigure[cow.pdf][width=1cm]}
         \placefigure{beta} {\externalfigure[cow.pdf][width=2cm]}
         \placefigure{gamma}{\externalfigure[cow.pdf][width=3cm]}
         \placefigure{delta}{\externalfigure[cow.pdf][width=4cm]}
     \stopfloatcombination
\stopplacefigure

\stoptext

as that started out as experiment and was used in specific styles it was 
never documented (example from source)

(mayb i'll add \startplacefigurecombination some day)

Re: float combinations

Hans, you forgot to define a \testitem...

\starttext

\definelabel[test][text=,numberconversion=character,stopper=!]

 \define[1]\testitem{{#1} {\test}}

\resetcounter[test]

\startcombination[2*2]
    \testitem{first}
    \testitem{second}
    \testitem{third}
    \testitem{fourth}
\stopcombination

\stoptext

Now, adding
\setupcombinations [before={\resetcounter[test]}]
would be incorrect as the counter would get reset for each row...

I cooked up something experimental ... after several variants i ended up 
with a solution that is only available in the keyword variant:

\useMPlibrary[dum]

\starttext

First line.

\startplacefigure[location=here,reference=first,title=first]
     \externalfigure[dummy][height=2cm]
\stopplacefigure

Second line.

\startplacefigure[location=here,reference=second,title=second,group=alpha,groupsuffix=.a]
     \externalfigure[dummy][height=2cm]
\stopplacefigure

Third line.

\startplacefigure[location=here,reference=third,title=third]
     \externalfigure[dummy][height=2cm]
\stopplacefigure

Fourth line.

\startplacefigure[location=here,reference=fourth,title=fourth,group=alpha,groupsuffix=.b]
     \externalfigure[dummy][height=2cm]
\stopplacefigure

Fifth line.

\startplacefigure[location=here,reference=fifth,title=fifth,group=alpha,groupsuffix=.c]
     \externalfigure[dummy][height=2cm]
\stopplacefigure

Last line: \in[first] / \in[second] / \in[third] / \in[fourth] / \in[fifth].

\page

\placelist[figure]

\stoptext

(beware: it's groupsuffix, and not suffix as that will add another one 
not tracked in the lists)

He's missing a closing bracket on the \externalfigure[mill] line.
Here's a complete example:

\setupexternalfigures [location=default]

\defineitemgroup [subfigure] [lefttext=, stopper=]
\setupitemgroup  [subfigure] [a, text]

\starttext

\startbuffer
  Dutch scenery
  \startsubfigure

A cow is shown in \in{figure}{a}[fig:scenery] and a mill in

Hi Alan, 
Thank you for your reaction and your suggestions.
Indeed, it is not exactly what I envisaged. I would be happiest if there were a way to add a and b as a suffix to the number, like Figure 2a.
With combinations it is easy to have a general Caption and specific captions for the components of the combination. But for the List of Figures I see no other possibility than, for instance "2   Dutch scenery. a. Cow, b. Mill". 
In fact I have no problems when I can make use of a combination, but, as I wrote, sometimes combinations are impossible for lack of space on the page.

What you describe as a challenge for Hans could be perfect, I think, provided an itemization can be interrupted and continued on next page. (I tried your liitle code snippet but ConText would not have it.) 
Splitting a float combination might turn out to be simpler. Only I have no clue as to how to achieve that.

Thanks again.

Best regards,

I think this could be a useful feature.

It's not that simple. You need other itemgroup settings as well,
otherwise you don't know the lefttext, righttext, stopper, etc.
options which are required for consistency, the sole purpose of this
feature.

Re: float combinations

This is probably not exactly what you want, however, one can use list=
in \startplacefigure\stopplacefigure to differentiate between the
figure caption and its listing in the list of figures.



\startplacefigure [title={Dutch scenery.
    \startitemize [n]
    \startitem A cow. \stopitem
    \startitem A mill. \stopitem
    \stopitemize},
    list=Figure title,
    reference=fig:scenery]

    \startcombination [2]
        {\externalfigure [cow]  [width=.5\textwidth]} {a}
        {\externalfigure [mill] [width=.45\textwidth} {b}
    \stopcombination
\stopplacefigure

A cow is shown in \in{figure} [fig:scenery]a.




The above example raises the following (low priority) feature
suggestion: How about some way of automatically numbering/labeling
combinations just like item lists? Sort-of a hybrid between
combination and itemize. Say,
\startcombination [r*c] [item=a]
    \startitem \externalfigure [cow] \stopitem
    \startitem \externalfigure [mill] \stopitem
\stopcombination

Hmm. A challenge for Hans (as if he is not busy enough).

(However, I am sure that Wolfgang can suggest an obvious solution that
is already available, that I overlook... :)

float combinations

[Robert Blackstone]

[-- Attachment #1.1: Type: text/plain, Size: 2293 bytes --]

Dear all,
A few days ago (10 April 2013, Vol.106, Issue 25) I posted a question about giving related but not necessarily adjacent floats the same number, as for example Fig. 2a and Fig. 2b.
In the meantime I found a, not very elegant, solution that only partly satisfies me.
Here is a working example: (I trust the cow and the mill can be found).
 %---------------------------------------------------
\useexternalfigure[SmallCow][cow.pdf][height=2cm] 
\useexternalfigure[MediumCow][cow.pdf][height=3cm] 
\useexternalfigure[Mill][mill.png][height=3cm] 
\definelist[figure]
\setuplist[figure][prefix=yes,label=yes,alternative=c]

\starttext
This file is for testing the possibility of giving two related musical examples (in old and modern notation respectively) the same figure number with a. and b. as suffixes to the number proper. 

\placefigure[here][SmallCow1]{A small cow.}
{\externalfigure[SmallCow]}  

A cow again, in two sizes.

\in{Figure}[SmallCow2]a shows the same cow as \in{Figure}[SmallCow1]. 
\placefigure[here][SmallCow2]{{\bf a}. Another small cow.}
{\externalfigure[SmallCow]} 
And here a larger cow (\in{Figure}[MediumCow1]b).

\setnumber[figure][1]
\placefigure[here][MediumCow1]{{\bf b}. A larger  cow.}
{\externalfigure[MediumCow]} 

And here comes a mill.
\placefigure[here][Mill1]{A mill.}
{\externalfigure[Mill]}  

\page
{\bf List of Figures}
\placelist[figure]
\completecontent
\stoptext 

%----------------------------------------------------
This way "a" and "b" become part of the caption text, resulting in: Figure 2     a  A small ….. etc., and: Figure 2     b  A larger …etc. Likewise in the List of Figures. This is not what I would like.

Is there a possibility, when not using Combinations, to get: Figure 2a    A small …..  etc?

Wherever possible I use Combinations but in some cases examples to be combined are very different in size and shape and/or too large to fit on one page together, so that one of them gets cut off.
Is there a possibility, when using a combination of figures, to split it, in other words, to separate the figures spatially, to allow them to appear on consecutive pages, and maybe even allowing some text in between?

Thanks in advance.

Best regards, 

Robert Blackstone
