General Float Placement Question

General Float Placement Question

[Randall Skelton]

[-- Attachment #1.1: Type: text/plain, Size: 877 bytes --]

Hi all,

Is it possible to combine placement attributes when specifying a floating
figure or table?

\placefloat[.1.][ref,..]{.2.}{.3.}
.1. left right here top bottom inleft inright inmargin margin page opposite
always force tall
.2. text
.3. text

In my case, I'd like to ensure that figures in a double-sided document
appear together, with the first on the left page and the second on the
right.  What I have reads:

\placefigure
  [90,opposite]
  [Fig:a]
  {Figure a caption goes here}
  \externalfigure[a][width=0.8\makeupheight]}

\placefigure
  [90]
  [Fig:b]
  {Figure b caption goes here}
  \externalfigure[b][width=0.8\makeupheight]}

For the first figure, will a location of [90,opposite] ensure a rotated
left-page figure?  Likewise, is it possible to ensure that the second figure
is forced to the next right page?

Cheers,
Randall

Many thanks for the reply Hans.  I'm a little puzzled by what happens when I
use \setuppagenumbering[alternative=doublesided].  For example:

\showframe
\setuppapersize[letter][letter]

\setuppagenumbering[alternative=doublesided]

\setuplayout[
    grid=no,              % grids make a mess of complex float placement
    topspace=0.50in,      % the space at the very top of the page
    backspace=1.75in,     % the space for binding gutter
    header=0.40in,        % the space for headers
    footer=0.40in,        % the space for footers
    leftmargin=0.75in,    % the space for margin notes
    rightmargin=1.00in,   % the space for margin notes
    height=fit,
    width=5.25in]

\startspread

\placefigure
 [page]
 [Fig:a]
 {Figure a caption goes here}
 {\externalfigure[a][width=0.8\makeupwidth]}

\placefigure
 [page]
 [Fig:b]
 {Figure b caption goes here}
 {\externalfigure[b][width=0.8\makeupwidth]}

you can also try this:

\startpostponing
\placefigure
  [Fig:a]
  {Figure a caption goes here}
  {\externalfigure[a][width=0.8\makeupwidth]}
\page
\placefigure
  [Fig:b]
  {Figure b caption goes here}
  {\externalfigure[b][width=0.8\makeupwidth]}
\page
\stoppostponing

it's actually trivial to provide: 

\starttext

\dorecurse{10}{\input tufte \par}

\placefigure
  [leftpage]
  [Fig:a]
  {Figure a caption goes here}
  {\externalfigure[a][width=0.8\makeupwidth]}

\placefigure
  [rightpage]
  [Fig:b]
  {Figure b caption goes here}
  {\externalfigure[b][width=0.8\makeupwidth]}

\dorecurse{10}{\input tufte \par}

\stoptext

i'll send you a patch 

Hans
