figure placement

figure placement

I am typesetting a small book and have run into two difficulties placing
figures, which are constrained to even, i.e. left hand, blank, pages.

The first place figures appear are opposite each new section. I coerce
this with the following commands:

\page[left]
\noheaderorfooter
\placefigure
\page
\section

This scheme works when the previous section ends on an odd page, but when
the section ends on an even page, \page[left] correctly inserts two blank
pages, but the first, instead of being blank, retains a \vrule\pagenumber
in the running head. It is little work to remove these artifacts with
Acrobat, but I prefer these headers were empty.

The second place figures appear is within sections. I use the same set of
commands, which places the figures where I wish, but each figure must be
placed precisely at the bottom of an odd page. This looks OK if the bottom
of the page coincides with the end of a paragraph, but otherwise the last
line is not flush right. I am looking for a solution that says, 'place
this figure on the next blank even page disturbing the text flow as little
as possible.' I have tried postponing, but without success.

The attached archive includes a test file, an empty graphic and the pdf
result. The ninth page shows the recalcitrant \vrule\pagenumber, and the
eleventh page shows the result of splicing a figure in mid-paragraph.

Any suggestions how to resolve these issues would be greatly appreciated.

Cheers,

Michael A. Guravage

I often have a set of macros that does a soemthing like this:

   \def\leftpage
     {\page \ifodd\pagenumber \noheaderandfooter~\page \fi}
   \def\rightpage
     {\page \ifodd\pagenumber \else \noheaderandfooter~\page \fi}

does that help?

Have you tried putting the figure in a footnote yet?

when a float does not fit it's pushed on a stack, and due to the way we 
flush it may end up later in the order (esp when a next float does fit 
on the page); in that case context will renumber the floats

I solved my immediate problem by using a separate layout with a slightly 
bigger text area: the image doesn't float to the next page any longer. 
I'm still curious to know what went wrong, but since my setup is rather 
complicated I need some time to make a good minimal example. (I'll put 
it on my to do list...)

Thanks,

Jelle

Sorry no time now, but I'll try to make an example on Monday.

Please make a example because this works for me:

\setupexternalfigures[location=default]

\define[3]\picturefile
   {\placefigure[force]{none}{\externalfigure[#2] 
[width=#3mm,orientation=#1]}}

\starttext

\input knuth

\picturefile{0}{cow}{100}

\picturefile{180}{cow}{100}

\stoptext

Wolfgang

Hi Hans,

Is there a way to do this [force] with \externalfigure in a macro def like:

\def\picturefile 
#1#2#3{{\rotate[rotation=#1]{\externalfigure[#2][width=#3mm]}}}

When I try to do something with \placefigure I get a "floatblocks : 
order disturbed" error and no figure placed.

Thanks again,

Jelle

\placefigure[force]{}{}

sometimes adding always helps (here,always) or fixed

all have their pro/cons

figure placement

[Jelle Huisman]

Hi again,

I try to get a picture on a page using 
\externalfigure[name.pdf][width=\textwidth] The image is pushed to the 
next page, even though there is no text on the current page and the 
height of the image itself is smaller then \textheight, so it should 
fit. How do I force image placement *here*?

Thanks again,

Jelle
