I made a screenshot to show the issue, here a minus sign is missing an the doublearrows are wrong
I cannot reproduce this on WinXP. Maybe you have an older "OpenSymbol" font on your system from a previous OO 2.x installation? Current version is 1.11, please check - for this version the display of "equal" and "minus" signs has been improved... I checked it, the version of the opensymbol font in windows font folder is 1.11. MRU->HDU: could you please have a look? I will attach a sample formula, where the described problems will be shown. E.g. in a 2^-t the minus is not displayed or only one line of a double line arrow. This happens only under Win Vista. Created attachment 60399 [details]
Sample formula; problem is in active OLE mode AND metafile
@ih: this problem is exactly the same problem as in issue 82685 (and indirectly issue 87901) which are both supposed to be fixed with OpenSymbol 1.11. The problem still happens with exactly that version of OpenSymbol though, so I guess OpenSymbol needs to be reworked again. As the minus sign is just a rectangle adding the hints should be rather trivial for any reasonable font-editor. starting to create TT-Hints for the font... Created attachment 60785 [details]
OpenSymbol 1.12
please check Version 1.12 of the font - but this is just a first release with hinting - more will follow *** Issue 84297 has been marked as a duplicate of this issue. *** due to some tests, set to Windows all problems will be fixed by adding TT-Hinting to the font (outline base will be 1.11 without extra thick strokes for = and - and some other chars...) so we get better results after all @all: please test the attached OpenSymbol Font (with Hinting) on VISTA! Does it fix our problems? Created attachment 64032 [details]
Version 1.21 of OpenSymbol Font with Hinting
@all: Anybody out there for testing this on VISTA? I will take a look... I already had a look on it with my Vista Notebook. Looks good until now. Is it also of interest to test this on Win 7? I could do that on my Home-PC where I have inatalled the Win 7 RC. Windows 7 might be interesting: We should check this on as much platforms as possible, because I want to put this new version of OpenSymbol (1.21- with hinting) into the OOo 3.2 release. Some bugs are duplicate to this and all have to do with the disappearing of tiny parts of some symbols - so hinting should fix them all. On Mac the new font is OK, even on 45% Zoom-Rate. ->ih 1.21 looks great but it still shows the "asymetric" equal symbol rendering at some zoom levels. I mean when the upper or the lower bar of the equal symbol is rendered as thicker than the other one - see the attached screenshot. In Math, I see the problem at zoom levels between 147% and 165% with the default font settings. 1280x800, Windows Vista SP1, subpixel rendering on. Created attachment 64104 [details]
Screeshot of bad equal symbol rendering. OpenSymbol v 1.21 with subpixel rendering on.
Another issue: the lower part of the gamma symbol (%gamma) is missing at zoom levels >115% in the same conditions as specified in desc19. You can see that too in the screenshot I attached. This issue was also present in previous versions of the font (and least in 1.10 and 1.11). On the Mac Platform both parts of the equal sign are rendered in the same size - I think it no such big problem if on some platforms the parts have different sizes. I is only a problem if one part completely disappears. The "disappearing lower part"-problem of the gamma symbol can not be fixed in the font itself it is due to the rendering in writer or/and formula editor. This new version of the font with Hinting does fix a lot of our disappearing problems and so I think we should put this version into OOo3.2 - It is of course better than the old one @troodon: can you please attach the document of your sample formula It looks like there are some other fixes in Office that improve the quality of the rendering. I have attached a screenshot of 99047.odt made on Mac with DEV300m52. Created attachment 64107 [details]

Screeshot of bad box brackets rendering. OpenSymbol v 1.21 with subpixel rendering on, 105% zoom level.
->ih In desc25 I've attached the Math document showed in desc20. In desc26 I've attached a Writer document with many formulas you can test with too. In desc27 I've attached the same Math document as in issue 85391 and I've done so because at zoom levels between 105% and 114% and around 85% to upper part of the box backets is not shown, as you can see in the screeshot from desc30. 1280x800, Windows Vista SP1, subpixel rendering on. If forgot to add that the documents from desc26 and desc27 use the DejaVu Serif font for text. Also, if you compare the screenshot from desc30 with the one from issue 85931, you can see the symbol rendering has improved a lot! @troodon: so if you also think that the quality of the font has improved a lot - do I have your OK to put this version into OOo3.2? I think the initial problem of this bug is fixed. If we have additional problems we should file new bugs. I want to use this bug and it's dependencies to check in Version 1.21 of the font. Some of the new problems that have come up here can not be fixed in the font itself. @all: is it OK for all of you, that I set this bug to fixed and check in the new font? ->ih Not so fast! :-) Tested the document from desc27 with OpenSymbol 1.21 in Windows XP SP2 (1024x768) and the results are not so good: at 70% zoom level + is rendered as | and = is renderes as -. See the attached screenshots Should I open new issues for the gamma and the box brackets problem? Created attachment 64145 [details]

Screenshot of tescase from desc27. Windows XP SP2, 1024x768, subpixel rendering off, zoom level 70%
->ih Plase ignore what I said in desc34 about Windows XP because the font wasn't properly updated and the screenshots show an older version. Now you have my ok ;-)! Even if there are some little problems, v 1.21 is much better than older versions. Created attachment 64148 [details]
Screenshot of tescase from desc27. OpenSymbol 1.21, Windows XP SP2, 1024x768, subpixel rendering off, zoom level 70%
MRU->troodon: what you described in desc34 ("at 70% zoom level + is
rendered as | and = is renderes as -") - are these regressions to openSymbol 1.11?
From my Point of view I cannot complain about the quality of OpenSymbol 1.21 (an
indeen, it is my job to complain ;-) ).

Another good test document
@mru: Thanks for the great test document. It looks okay on WinXP SP3. @all: To make a long story short: It is time to mark this issue as "fixed". @ih: Please proceed. @mru: troodon said in his last comment that he had regressions the new testdoc also looks ok on Mac - we never had such a great qualitiy of the font and a lot of all our old problems about disappearing parts of some glyphs are fixed so everybody is satisfied and I set this to fixed - the new version will make it's way into OOo3.2 in CWS Extras320 @troodon: please file bugs for the other last minor problems I have checked v1.21 now on WinVista, Win7 and Ubuntu 64bit. I agree with all of you that this is definitely the best OpenSymbol font we ever had. ->mru See desc37 :-) ->ih I've filled issue 104239 (gamma issue) and 104240 (brackets issue). Should I fill another one for the "small" problem (desc22) of one bar of the equal sign being rendered as thicker as the other one (desc19 and desc20) or is a "wontfix" case? Thank you for your great work! ->troodon: thanks for your help - please file another issue for the problem with the bars of the euqual sign ->ih Filled issue 104299 for the equal sign bars problem. Thank you! Verified in CWS extras320. |
It happens, that when i insert a Formula into a textfile, that certain signs in the formula are not shown, or shown incorrectly. mainly this happened with vector arrows, and minus signs in a x^{-y} like expression. If i export the file as pdf or print it the signs are correct.
