I can't get references to work -- maybe I'm making some beginner's mistake. Anyway, the output from the following file contains "??" where the page numbers should have been: %%%%%%%%%%%%%%%%%%%%%%%%%%%% \starttext \title [pointer1] {The title} Some text. \subject [pointer2] {A subject} Some more text. Bla, bla \at{page}[pointer1] bla bla bla \at{page}[pointer2]. \stoptext %%%%%%%%%%%%%%%%%%%%%%%%%%%% Note: I'm using the latest stable release (March 3, 2003). Best regards Stefan
Hi, I have several small figures and want to place them in two columns as follows: ___________ __________ | | | | | | | | | Figure | | Figure | | | | | |__________| |__________| Fig 1. blabla Fig 2. blabla I tried use columns \startcolumns[n=2] \placefigure[here][fig:1]{blabla}{\externalfigure[fig1]} \columns \placefigure[here][fig:2]{blabla}{\externalfigure[fig2]} \stopcolumns It seems work depend on the pagebreak and not works all time. If there are a pagebreak before or after the block of these figures, it not works well. The \placesidebyside and use combinations will give one float Figure with the two pictures as subfigures. But what I want is two figure. thanks Wang

I find floats difficult. They do weird things. I tried to create a minimum file that shows your columns of figures behaving badly -- I didn't succeed. Here is the test file I created: ----- \setupcolors [state=start] \startuseMPgraphic{fig1} w := 4cm ; h := 2cm ; ww := 1cm ; hh := 1.5cm ; fill (0,0)--(0,h)--(w,h)--(w,0)--(ww,0)--(w,hh)--(ww,hh)--(ww,0)--cycle ; \stopuseMPgraphic \starttext \input tufte \startcolumns[n=2] \placefigure[here]{blabla}{\useMPgraphic{fig1}} \column \placefigure[here]{blabla}{\useMPgraphic{fig1}} \stopcolumns \page \startcolumns[n=2] \placefigure[here]{blabla}{\useMPgraphic{fig1}} \column \placefigure[here]{blabla}{\useMPgraphic{fig1}} \stopcolumns \input tufte \stoptext %%% Local Variables: %%% mode:context %%% End: ----- You may have to post a more complete example that demonstrates where ConTeXt is behaving badly.
I also think the problem is caused by placing the floats to the nofloat cloumns block. Is there another way to this?

Hi Lei Wang,
I have several small figures and want to place them in two columns as follows: ___________ __________ | | | | | | | | | Figure | | Figure | | | | | |__________| |__________|
Fig 1. blabla Fig 2. blabla
I tried use columns \startcolumns[n=2] \placefigure[here][fig:1]{blabla}{\externalfigure[fig1]} \columns \placefigure[here][fig:2]{blabla}{\externalfigure[fig2]} \stopcolumns
It seems work depend on the pagebreak and not works all time. If there are a pagebreak before or after the block of these figures, it not works well.
The \placesidebyside and use combinations will give one float Figure with the two pictures as subfigures. But what I want is two figure.
The normal double column mechanism tries to place a graphic, stores it when there is no place, and flushes it as soon as possible. The \startcolumns mechanism works well intermixed with the standard one column mode. In your case, esp for vertical chinese, use columnsets: \startcolumnset \placefigure[tblr:1]{}{} \placefigure[tblr:2]{}{} \input tufte \stopcolumnset This will place the floats on top of the first and second column; an alternative usage is: \placefigure[tblr]{}{} \placefigure[tbrl]{}{} Think of tb meaning flush from top to bottom, and lr to mean from left to right; so, there are quite some ways to place/flush a graphic. (also play with: \placefigure[fxtb:2*3] and [fxbt:1*18] which gives you absolute placement; big floats will span columns, so something: \definecolumnset[chinese][n=10] \startcolumnset[chinese] \placefigure{}{} \stopcolumnset should work ok Hans ------------------------------------------------------------------------- Hans Hagen | PRAGMA ADE | pragma@wxs.nl Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: +31 (0)38 477 53 69 | fax: +31 (0)38 477 53 74 | www.pragma-ade.com ------------------------------------------------------------------------- information: http://www.pragma-ade.com/roadmap.pdf documentation: http://www.pragma-ade.com/showcase.pdf -------------------------------------------------------------------------

Thanks. It place the figures side by side correctly. But, there is another problem. After the two figures, it force a page break and leave a large blank even though the blank area can accommodate the next paragraph. I attached the test file and waht I really want is: One column texts two figures sidebyside One column texts Thanks. Wang

Well, here you run into the difference between columns and columnsets. Columnsets can be mixed with one column mode, but you need to balance (automatic balancing is pretty hard for complex columnsets, so this is not yet in the kernel, but manual balancing is (one can set the number of lines per column). However, it seems that you want something: \starttext \startbuffer \startcombination {\externalfigure[cow][frame=on, width=3cm]} {\placefloatcaption[figure]{x}} {\externalfigure[cow][frame=on, width=3cm]} {\placefloatcaption[figure]{y}} \stopcombination \stopbuffer \placefigure{none}{\getbuffer} \stoptext This special feature (separate captions) was introduced quite some time ago for Karel W so you should buy him a beer. When testing this i foun dout that there is an error in the macro. A few days ago i added the 'distance' key to caption setups, and (of course) i didn't test that with free floating captions (unresolved intermediate macro). So, in page-flt you need to replace the following bit of trivial code: \def\dodosetfloatcaption[#1][#2]#3% to do namespace for number/ascii {\ifnofloatnumber % also handle trialtypesetting \letgvalue{@fl@r@#1}\relax \letgvalue{@fl@t@#1}\relax \else \verhoognummer[#1]% \maakhetnummer[#1]% \globallet\flhetnummer\hetnummer \setgvalue{@fl@r@#1}% {\dofloatreference \redofloatorder{#1}% \doschrijfnaarlijst{#1}{\flhetnummer}{#3}{#1}% \doglobal\convertargument#3\to\flasciititle % \asciititle is global \doifsomething{#2} {\rawreference\s!flt{#2}{{\flhetnummer}{\flasciititle}}}% \letgvalue{@fl@r@#1}\relax}% nills \setgvalue{@fl@t@#1}% {\preparethenumber{\??kj#1}\flhetnummer\preparednumber \doattributes{\??kj#1}\c!letter\c!kleur {\doattributes{\??kj#1}\c!kopletter\c!kopkleur {\labeltexts{#1}{\preparednumber}}% \doattributes{\??kj#1}\c!tekstletter\c!tekstkleur {\dotfskip{\getvalue{\??kj#1\c!afstand}}#3}}}% THIS LINE WAS WRONG \fi} Hans ------------------------------------------------------------------------- Hans Hagen | PRAGMA ADE | pragma@wxs.nl Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: +31 (0)38 477 53 69 | fax: +31 (0)38 477 53 74 | www.pragma-ade.com ------------------------------------------------------------------------- information: http://www.pragma-ade.com/roadmap.pdf documentation: http://www.pragma-ade.com/showcase.pdf -------------------------------------------------------------------------

Hey, I thought it was me who requested this feature? (I remember needing it for side by side floating tables when it still wasn't implemented ...)
actually, that was the moment it was cleaned up and moved from the particular style to the core files; the reason for decoupling them was in a special kind of float where clicking on the caption brought up a big float in a widget (whichin turn was based on the widget based help system) -) [this is why in page-flt there is still the mapping to old names used in 'uguide']
BTW, AFAICS there is no way to make a reference (à la \infigure) to a single element in a /combination/ ... can this be done?
there is a trick for that, but i cannot find it right now; however, the floatcaption command accepts a second optional arg being the ref.

Well, here you run into the difference between columns and columnsets. Columnsets can be mixed with one column mode, but you need to balance (automatic balancing is pretty hard for complex columnsets, so this is not yet in the kernel, but manual balancing is (one can set the number of lines per column).

Dear Lei, It's silly, all I did was ask a question. Then Hans starts working on answering it and takes care via you to send me beer. It's generosity to the limit. Don't. We all owe context to hans and to his able debuggers and enjoy using it. For me he has made typesetting documents easier and funnier and beautifullier too. Next time I visit Hasselt I'll bring him a reward. Karel W. On 11 Mar 2003, at 14:48, Lei Wang wrote:
