In my macros from 2015 I’m still using manual right/left page
versions, and I’d like to enhance them.
I need e.g. different \offset values for \externalfigure depending on
right/left page.
normally you will use "inner*" and "outer*" placement there as in other
cases (which uses the same tricks)
I have one macro to place an page-width image with bleed, it uses
\placefigure[top] and then \offset to move the image, so that it starts
with bleed on the top side and with/without on the left side depending
on a parameter that I change manually if the page breaking changes. The
caption must stay within the type area – that works so far.
But it shouldn’t be necessary to define left/right manually, and that’s
my question: if these \doifs work correctly within a float placement.

The rightpage check combined with putting a signal at the spot where
you test will work ok.
The odd/even test works as expected when you're in the page builder
(wrapping up the page).
