Re: [libreoffice-users] How to place subscript indices close to the variable they belong to in the equation editor?

Hi :)
I'm not sure if the guide helps
https://wiki.documentfoundation.org/Documentation/Publications#LibreOffice_Math_Guide
because the bug-report suggests it's a feature that might need rethinking.

It's interesting to see that when there is a superscript it looks
fine.  Can you cheat by adding a 1 as a superscript "for clarity"?
Would they buy that excuse?

Btw  in "Math" (the name of the formula editor) you can use the proper
symbol instead of using "f".  Use keyboard shortcuts or the menus to
copy&paste this into the lower-pane in Math

int _{0}

It might be worth considering writing either just the formulae or the
entire document in something else such as inkscape, scribus or LaTeX.

Apparently with Scribus the best work-flow is to write the text in
Writer and then copy that into Scribus so that Scribus can sort out
the layout.  Scribus is really a desktop publishing program (DTP)
rather than a word-processor.  I'm not sure how fine-grained it can go
so just experiment with a small portion to see if it can handle the
kerning issue, ie allow you to manually adjust the spacing between the
subscript and the "f".

LaTeX is allegedly difficult to learn and you kinda have to stick with
it's default formatting.  However those defaults are likely to be
exactly what you need and if some then you could focus on the writing
and let the LaTeX editor worry about the layout more.

Inkscape really isn't the right tool and might be a bit of a
nightmare.  If you do use it it might be better to save each equation
as a separate file and then bring each equation into the Writer.
Maybe give it a go with 1 simple equation first.  It's more of a
graphics editor and not a word-processor or DTP at all.  However when
you do write it allows you a LOT of control over kerning and all
sorts.  Unfortunately it's tricky trying to use it to create
text-elements that show-up properly in Writer.  Avoid creating a
text-box.  Just click where you are going to start writing and then
start typing.  Let inkscape calculate how the text-box should look.
Then instead of using _ to create a subscript character just type in
whatever is going to be in the subscript and then sdelct that and use
the icons-bar at the top.  The advantage with inkscape is that it lets
you sort out a lot of the kerning issues by selecting the text and
using
Alt keyboard arrows
To get the 'page' size down (or up) so that the text fills the 'page' try
File - "Document Properties" and it's kinda obvious from there
(another 2 clicks)

If you are considering Inkscape then another tool to consider might be
the Gimp or another image editor.  Again it's likely to be a
nightmare.  Again it's just small text-boxes to create graphics
elements.  It's not as good at editing text but you can create
different sized text-boxes and have them overlapping.


So, hopefully someone else has better ideas!

Tom :)
