Hi,

right now I use \currentreferencerealpage to detect if I'm on an even or odd page (because my picture placement rules depend on it) like this:

\newcount\bildpage \bildpage=1 % ... \def\bild#1...{% {\global\bildpage=\realpageno}% \ifodd\bildpage \def\eo{o}\else \def\eo{e}\fi % ... \if o\eo odd...\else even...\fi \message{>> bildpage=\the\bildpage \space eo=\eo \space currentreferencerealpage=\currentreferencerealpage \space << }% }

but now I notice that for some pages/pictures the value of \currentreferencerealpage is not correct (only for the first picture on a new page?):-(

To test whether you’re on a left or right page you can use the \signalrightpage and \doifrightpageelse commands

this doesn't seem to work well -- at least not within \placefigure

I've tried this replacement in my \bild macro which should be equivalent (or better?)

% \ifodd\bildpage \def\eo{o}\else \def\eo{e}\fi % \ifodd\bildpage \def\lr{r}\else \def\lr{l}\fi \dontleavehmode\signalrightpage \doifrightpageelse{\def\eo{o}}{\def\eo{e}}% \doifrightpageelse{\def\lr{r}}{\def\lr{r}}%

(with and without \dontleavehmode\signalrightpage) and now I get more wrong picture placements for the first picture on some pages...

you need to make sure that the signal travels with the stuff you're checking btw, if you use side floats, the inner/outer variants do this auto left/right stuff ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | voip: 087 875 68 74 | www.pragma-ade.com | www.pragma-pod.nl -----------------------------------------------------------------
