How to center with picture taken into consideration
I keep bugging the list. ;-) I center some text on a place where I also place a picture on the right site. Is it possible to center on the part that is not taken up by the picture? The picture is placed with: \definelayer[picture][ preset=righttop, width=\textwidth, ] \setlayer[picture]{\externalfigure[graphics/pasfoto]} \setupbackgrounds[text][text][background=picture] \setupbackgrounds[state=repeat] To make things a little more complicated, the placing of the picture is conditional. So it is not always done. -- Cecil Westerhof
Hello Cecil, I have a LuaTeX-based start for you, but there is one important thing I do not know: how to obtain the an image's width and/or height from Lua. Although that would also depend on whether you want to resize images to a fixed with, etc. Anyway, now that the typesetting code is Lua-based, working out the conditional stuff you need will hopefully be trivial (for 'if you know Lua or have an hour to learn the basics' values of trivial).
