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... I vaguely remember that {\global\bildpage=\currentreferencerealpage}% {\global\bildpage=\realpageno}% was a hack from Hans to work arround "issues" to get the real page number within those floats ?!
