Hi,
I ran into a \setlayer problem while including a bitmap graphic from a
figure database. The position of the gfx was slightly shifted to the
right. No problems, if I included the identical graphic from a single file.
\setlayer[foo][x=0pt,y=0pt ]{\externalfigure[gfx_from_a_db.png]}% shift!
\setlayer[foo][x=0pt,y=50pt]{\vbox{\externalfigure[gfx_from_a_db.png]}}% ok
\setlayer[foo][x=0pt,y=100pt]{\externalfigure[gfx.png]}% ok
\setlayer[foo][x=0pt,y=150pt]{\hbox{\externalfigure[gfx.png]}}% shift
The result of \externalfigure differs (mode) for the two inclusion
methods. Also it looks like \setlayer does not ensure, that the content
is in the (position neutral) vertical mode. Is there a reason for this?
Currently I fixed it locally with
\ifhmode\vbox\bgroup#1\egroup\else#1\fi ,
but a more global approach would be prefered.
Any comments welcome.
Greetings, Peter
