Vertical lines don't scale properly

Postby elespinexiste » Tue Mar 22, 2016 11:46 am

Hi! Vertical lines don't scale properly, they are always too short, for instance with:
left lline matrix{1##2##3##4##5} right rline
The lines are centered, they embrace numbers 2, 3 and 4, but they don't reach the end, leaving numbers 1 and 5 uncovered.
Any idea?

Odd. Your formula code gives the correct result for me: the vertical lines extend to the full height of the matrix.

I know there have been some discussions here about problems with OO Math on Win10 but I don't remember the outcome.

I get the same results from that formula

left lline matrix{1##2##3##4##5} right rline also works fine on Mac OS X. I suspect this is a problem with later versions of Windoze, perhaps due to the fonts delivered with that operating system. Read some of the other recent topics in this forum about display problems on Windoze. Perhaps you'll find a solution there.

It might be misinterpreted (or faulty) size/spacing info in the fonts used.

Possible workaround: Add a superscript to the top element and a subscript to the bottom one:

left lline matrix{1^`##2##3##4##5_`} right rline

On my systems it shifts the numbers in question slightly left off center (hardly noticeable unless you know what has been done...), and the surrounding lines are just a tiny bit longer. For some cases of spacing/size error it might work as a quick fix. Font replacement is probably better in the long run.

It seems the Open Symbol font is not totally right.

On my Windows 10 it displayed like for the OP.

After extracting the zip OpenSymbol_V1.7_new6.zip from this message

https://forum.openoffice.org/en/forum/viewtopic.php?f=12&t=67772

into C:\Windows\fonts

Then closing AOO and reopening and again enter the formula from the OP all is well :bravo:

Formula looks now like the one from MrProgrammer :D
