Bug ID: 104749
Summary: poor formatting of a very simple formula
Product: LibreOffice
Version: 5.1.6.2 release
Hardware: All
OS: Linux (All)
Status: UNCONFIRMED
Severity: normal
Priority: medium
Component: Formula Editor
Assignee: libreoffice-bugs@lists.freedesktop.org
Reporter: j...@curioussymbols.com
Description:
The following formula renders very poorly in a standard installation of
LibreOffice:
1 over {2 %sigma} + 1 over a + 1 over %sigma
This problem was reported previously in bug 52225, but that bug was closed due
to one narrow part of the problem being solved, but not the whole problem.
The problem here consists of the default symbol font (FONTNAME_MATH) being set
to OpenSymbol. This is a crappy font that lacks proper font metric information
about the size of its symbols, and the result is that the %sigma in the last
term of the above equation hits its head on the division line, rather than
lining up with the denominators in the other equations.
Another problem here is the greek symbols still default to italics in all
equations. This default behaviour needs to be changed. Use of non-italic Greek
symbols is not consistent with other word processing programs (Latex, Word) nor
with conventional publishing (textbooks, journal papers).
Another problem here is that there is not even any manual way to override the
symbol font used in LibreOffice. It is hard-coded and can only be manually
changed one symbol at a time (and even then, it seems that LibreOffice reverts
the changes in some caseS).
In summary, these issues are quite a major barrier to the comfortable use of
current versions of LibreOffice for mathematical/technical publishing, and I
believe should be given quite high p
Steps to Reproduce:
Type the equation:
1 over {2 %sigma} + 1 over a + 1 over %sigma
Actual Results:
The '%sigma' from the last term is (1) not lined up with the other denominators
and (2) is not in italics as it should be, to match the 'a' of the second term.
Expected Results:
(1) all denominators should line up and (2) the font of %sigma should be
italic.
I should be able ot manually change the font/style of my greek symbols, but
there is nowhere I can do that.
Reproducible: Always
User Profile Reset: I have seen this issue on multiple LO versions and on
multiple machines. The crappy 'OpenSymbol' font is mostly to blame, as well as
the default non-italic form of most symbols, and the hard-wired symbol catalog.
