Skipped figure numbers
by Aidan Nichol 30 Mar '16

30 Mar '16

I have been looking at various options for controlling how figures are placed on a page and based on answers to similar questions in this mailing list I tried various options. The most flexible one seems to be using tables e.g. \setupexternalfigures[location={default}] \starttext \placefigure[]{}{\externalfigure[hacker][height=1in]} \startxtable[frame=off,align=low] \startxrow \startxcell[ny=2] \placefigure[force][]{left twoup}{\externalfigure[mill][height=4in]} \stopxcell \startxcell \placefigure[force][]{the first}{\externalfigure[spider][height=1.5in]} \stopxcell \stopxrow \startxrow \startxcell \placefigure[force][]{the second}{\externalfigure[cow][height=1.5in]} \stopxcell \stopxrow \stopxtable It seems to work well except that figure numbers are being skipped. In this example hacker=1 mill=8, spider=9 and cow=10. Varying the contents of the table reveals that It is skipping two times the number of figures in the table. Is this an invalid combination of features I’m using or am I doing something wrong?

Dear List, please help me with my problem here ....

Nested floatcombinations
by Aidan Nichol 30 Mar '16

30 Mar '16

Based on answers to previous questions the easiest way to arrange figures on a page in a simple tabular arrangement is to use \startfloatcombination etc. and indeed works well I wanted to get a single tall figure on the left and two on the right above one another. I tried nesting i.e. \setupexternalfigures[location={default}] \definefloat[floatA][floatAs] \definefloat[floatB][floatBs] \setupcaption[floatA][number=yes,location=top] \setupcaption[floatB][number=no] \starttext \startplacefloatA[title={Using figures in nested float combinations}] \startfloatcombination[nx=2,ny=1] \startplacefigure[title={left two rows}] \externalfigure[mill][height=4in] \stopplacefigure \startplacefloatB \startfloatcombination[nx=1,ny=2] \startplacefigure[title={right top}] \externalfigure[spider][height=1.5in] \stopplacefigure \startplacefigure[title={right bot}] \externalfigure[cow][height=1.5in] \stopplacefigure \stopfloatcombination \stopplacefloatB \stopfloatcombination \stopplacefloatA \stoptext This just gave the three figures in a sort of single column down the page. Are nested floatcombinations not allowed or have I done it wrong?

adding font feature tnum in the TOC
by Willi Egger 30 Mar '16

30 Mar '16

Hi, hm, I am a little puzzled… If I am correct then one should be able to enable the font feature tnum for the page-numbers with “pagecommand=“. I have \setuphead [section] [aftersection=\page, textstyle=\bfd, numberstyle=\bfd, align=middle, after={\godown[-1\lineheight]}, number=no] \setuplist[section][pagecommand={\addfeature[tnum]#1\subtractfeature[tnum]}] However if I do this then I get the pagenumber prefixed with ‘section’ e.g. bbb bar buch bühne section3 What am I doing in the wrong way? Kind regards Willi
