ZIPped Impres prezentation and screenprint wtih the problem
Impress presentation for replay to Comment 7 |
||
Running the full screen presentation shows oversized, deformed symbols whenever was may last changes! Run the presentation show! I will have to show it on Monday to the people. How it look like ... :( You have a screenshot of slide 42. It displays ok for me. I also tried editing the formula and then starting slideshow from slide 42, but it was still ok. Win 7 Pro 64-bit, Version: 5.0.2.2 (x64) Build ID: 37b43f919e4de5eeaca9b9755ed688758a8251fe Locale: fi-FI (fi_FI) Please try with LibreOffice 5. If you can't get the slideshow to work before your presentation today, maybe create a PDF of it.. Set to NEEDINFO. Change back to UNCONFIRMED, if the problem persists. Change to RESOLVED WORKSFORME, if the problem went away. Sorry but please look again at the screen shoot "slide 42 - Edited formula symbols geting crayzy.png". I would send it again of it was possible. The marked formula (in orange border) is there compared to the similar formula above; the invalid symbols are linked there by arrows with original, good versions.
You can't miss differences. Especially {%idelta %ikappa} are deformed and %ialphas are also changed. Any formula edited now has "degenerated" symbols.
For today presentation I have've used PDF exported version. it looked fine.
[Maybe it is problem with how the symbols are displayed in The Impress application, taking into consideration its size change, multiple copying and editing.]
When I opened *.odp on computer in my office at work it also looked good, but I haven't tried edition.
Back home there is no improvement but I'm before upgrade of my LOtDF to newer version and PC architecture tough I'm still using x86 version.
The 5.0.2.2 x64 version is being downloaded at the moment.
I Will give You to know about results and change the bug status accordingly.
Kind regards.

I found, that the problem arise when scaling formulas (size change) even thought I used proportional scaling. Program (Impress) seems to change font size to adopt formula better to the scaling, but sometimes it fails to fit the new font proportions to proportions based on initial font size being resized. One can ask way I didn't use font size change inside formula editor that I could. I didn't know where it was and it is simpler to scale outside formula seeing effect shortly without blinking, flashing & jumping when opening and leaving formula editor! I think I can help myself with deformed formula symbols (thought not other letters) under scaling by: 1. Setting default size of the formula - as an object form outside. 2. Editing the formula again and setting symbol size from inside of formula editor basing on the experience what size was doing fine on the page or making 'trial and errors' effort to chose such one (every time living editor). At least It works for me but it doesn't solve the main problem: deformations of symbols in formulas being scaled from outside of the formula editor. I'm changing status to NEW since there are new "discoveries" about the source of the problem. Hopefully this time You will be able to recreate the problem on your computer. Otherwise I don't believe you would help that - thought it will be "user specific". I'm also creating a thread about >Applay< button being needed for settings change and visual control without leaving a tool being utilised. Kind regards M.B. (In reply to prcwnl from comment #4) > > I'm also creating a thread about >Applay< button being needed for settings > change and visual control without leaving a tool being utilised. > It is rather not a 'bug report' but a 'feature request' where I should post it? I lost main forum form my sight ... [ I have many experience with setting properties of lines and other objects in general where there is need for visual checking of the effect. Only 'trial & errors' method seems to work, which includes series of the same: tool opening, tuning, closing, visual checking, and so on ... Here arise following SUGGESTION: Please consider adding <Applay> button wherever any changes are made to apply them without leaving window/tool/editor - if possible and wouldn't create a bunch of new problems. { Imagine You're fitting length of the set of line sections between two other crossing lines, so that ends of every line section would touch the two crossing lines on both sides without gaps. If the line sections are groped together in second level of grouping You can't use right side tools for that to avoid a window with <OK> button being reopened every time You are not satisfied. The same you repeat with every object being fitted... } Many examples of that are in my presentation being already sent to you with bug report: https://bugs.documentfoundation.org/show_bug.cgi?id=95108 ] Never confirmed, so NEW is not correct. For feature requests, change the severity to enhancement. To be clearer: 1/ Did you try LO 5.0 ? 2/ How do you resize your formulas? In current version you can't resize a math formula with the mouse. It was possible in some version 4.x but it was a bug because a Math formula is not a graphic object. Set status to NEEDINFO, set it back to UNCONFIRMED once you have provided requested info, or to WorksForMe if the problem is gone. Best regards. JBF (In reply to Jean-Baptiste Faure from comment #7) Ad. 1) I have just installed LO 5.0 ver. x64, opened presentation with last uncorrected formula: the first formula on the right part of screen 3: color white {{color magenta N} = int from{A} %isigma(y) dA =0} It contains sigma `Symbol` font which is displayed deformed on my screen! I have just found new hint: the sigma symbol displayed deformed changes to normal proportions when I switched LO Impres window from full screen to smaller window using right upper corner icon (on the window bar - next to X). Switching back to full screen again changes the sigma symbol into deformed version. Ad. 2) To resize formulas you just: right click on the formula object from outside and choose from the context menu `Position & size` (not sure about English version of it). In the window that will appear you have to "unlock" size changes and set Width or Height of you preference - remembering to keep "aspect ratio" locked. P.S. The previous hints that I remember ware: a) problem is with symbols (like "sigma" not with normal letters; b) it doesn't meter if you use %isigma or %sigma version; c) it is somehow connected with its size change; d) it was not LO versions specific problem but met earlier - maybe from OOorg times.

Created attachment 121952 [details] Impress presentation for replay to Comment 7 The presentation contains formula with `sigma` symbol displayed deformed if document is being edited in full screen. Please don't change version to newer from original without a reason. Still not reproducible for me. Best regards. JBF (In reply to Jean-Baptiste Faure from comment #12) Must be a user specific or computer specific problem. Let it be as it is. Now I know what to do how if the problem appears somewhere: change the size of the object to original and than set font size from inside of the formula. Those formulas which I have corrected are looking good and cause no further problems - so far. I would say it works for me and there is no need to waste more of your time on the issue. Thank You for help. Kind regards Marek B. (In reply to prcwnl from comment #13) > [...] > I would say it works for me and there is no need to waste more of your time > on the issue. Ok, thank you. Closing as WorksForMe. Best regards. JBF |
Created attachment 119671 [details] ZIPped Impres prezentation and screenprint wtih the problem On the beginning it was working fine. After two weeks working on the presentation often and more often I have problems with edited formulas/equations. I'm changing something in a formula and after closing formula editor I do obtain edited one version but some characters are deformed, oversized. Looks terrible. Example in graphic attached. The only but temporarily (until the next editing) solution is to delete original formula and write new one. When I do mathematical transformation to the formulas (trying to show something that arise from the equations) the easiest way is to copy previous version of it, which is good prepared, worked out (including colours, positioning and size on the page) - just needs some editing - mainly symbols shifting. It saves a lot of time and frustration, especially when everything I have prepared in the previous but now edited (or copied and edited) version of it was fine. The only, but frustrating solution, I found is to copy contents of formula from formula editor and create new formula (pasting copied contents into new editor/formula session), position it, resize it and so on. Stays all the symbols and characters, colours which saves a lot of effort. All editing I do on previous original but broken version that I tan delete and create new formula. It is not the first time I've met the problem. I know it for years now. Met it on different computers (home, work, work laptop) and different OS, and The Office versions (including old OOorg if I can remember). Now it is W7x64 & LOtDF.Impres.4.4.5.2 but seems not specific to this version. Earlier I tought the reason was change between OOorg and LOtDF but hardly! I know the only common element: the user - the frustrated one ;) In attachment Zipped presentation and screenprint for Your investigation. Be aware: presentation is on Polish (!) But formulas are in Universal Math;) kind regards M.B. P.S. Maybe problem was generated when I temporarily copied some equations from Ms Office as an example to write my own formulas? I didn't edit them - thought it looked like blurred pictures without background anyway. Before there was no problems with my formulas in this particular document but could be coincidence.
