Description georgaubele 2003-11-10 15:46:49 UTC 
When using brackets in the formula editor, the upper and lower endings are not
displayed.
They are printed quite well, though ...

example:

left[ 2314 - 2342 right]
Comment 1 guido.pinkernell 2003-11-10 17:07:25 UTC 
Can confirm with OOo 1.1.0(en) on Win98.
Duplicate of Issue 16470?
Comment 2 thomas.lange 2003-11-11 09:09:48 UTC 
OK in SRC680 m13 with Win XP.
Only the lower border of the brackets is overwritten by the object
boundary. If one disables the drawing of the object boundary (see
"Tools / Options - StarOffice - Appearance" the checkbox for "Object
boundaries" listed in the "General" section) everything is fine.

TL->MRU: Please have a look if there is a problem with Win98.

In OOo 1.1 both endings can disappear - see attachment (disabled
objekt boundaries)
Comment 5 michael.ruess 2003-11-12 12:53:06 UTC 
MRU->TL: Can reproduce the problem on Win98. There the brackets look
as on Georg's Screenshot (even in the PrintPreview).
Comment 6 thomas.lange 2003-11-12 12:57:57 UTC 
TL->HDU: Please have a look.
Comment 7 hdu@apache.org 2003-11-12 13:04:06 UTC 
HDU->IH: The problem is similar to ones we had with the OpenSymbol
equal or greaterequal signs. The upper angle seems to go higher than
ascent + internal leading. I suggest to move it a bit lower and check
it with different zoom settings on W98.
Comment 8 nospam 2003-11-26 09:23:40 UTC 
IH: I have no time to do anything about that problem at the moment. Sorry.
Comment 9 michael.ruess 2003-11-26 10:35:38 UTC 
Ok, retargeted to OO later.

Can confirm this issue with OOo 1.1.3 under Windows 2000 Pro.

Also, don't forget to checkout the screenshots I present in my comment to issue
31787.

This formula is only correctly displayed at 400% zooming in page preview mode :
http://jmmolina.free.fr/t_30510/issue_22312_page_preview_400.png

So I guess the display problem comes from a line not drawn because its width is
inferior to 1, floating values used by vector graphics but converted, so
truncated, to integer values before display. So for example if the vector width
is 0.5 its rendered width, pixel size, is 0, so not displayed. I'm just
guessing, I have no idea how OOo renders the formula but I experienced the
problem years ago while working on 2D and 3D graphics engines.
