Apache OpenOffice (AOO) Bugzilla – Issue 110223
impress displays bold font as too bold
Last modified: 2017-05-20 11:33:26 UTC
I found impress in OOo 3.2 doesn't show bold font. I've tested with Debian unstable, Fedora 13 alpha and Windows XP. I saw this issue on Linux, not Windows. more detail and test case, see my post on Debian BTS http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=573622
Sorry, not reproducible on linux. This seems to be a font problem. Sure you have the used fonts installed?
Well, I can confirm this with some Japanese and Chinese fonts. And yes, it does not reproduce with other fonts. I've tested with - VL Gothic/VL P Gothic (it's default font in Japanese Linux desktop) - IPA P Gothic/Gothic/P Mincho/Mincho/UI Gothic - AR PL KaitiM Big5/AR PL KaitiM Big5 - etc... Could you test with above fonts?
we discovered kind of the same issue before and it resolved as follows: depending on the size of the font on screen, the system will use a different rendering method. For nearly identical screen sizes the rendering will look the same. For some descrete pixel values the rendering will then change which may look as if the font a now a little more bold when compared with the only 1 pixel smaller version. So for example a X with 10 pixel high might look nearly identical with an X 9 pixel hight but the same X 11 pixel high may look different as the system switched the rendering. To verify this, please make sure your text has the same size on screen in pixel (not same logical size) by making the document window (not including the toolbars, docking windows, e.t.c) the same size as in both versions.
>To verify this, please make sure your text has the same size on screen in pixel >(not same logical size) by making the document window (not including the >toolbars, docking windows, e.t.c) the same size as in both versions. I can confirm this with Debian i386, amd64 and fresh virtual machine (fedora 13 alpha) on KVM by newly created impress document. Can't you reproduce this, folks? If so, please tell me what should I give more to you.
Created attachment 68442 [details] test this with slide show
hdu: could you please comment on this issue? I guess this is an "embolden" issue of freetype library. Usually CJK fonts do not provide "bold" fonts. Cf. http://www.mail-archive.com/freetype-devel@nongnu.org/msg00050.html Note that I cannot reproduce on FreeBSD 8.0 of my vanilla ja build. it uses freetype come from the distribution. thanks
henrich_d: could you please attach the png version of http://www.openoffice.org/nonav/issues/showattachment.cgi/68442/boldfont-with-japanese-font.odp ?
Created attachment 68601 [details] OOo3.2.0 Impress in Debian unstable
Created attachment 68628 [details] OK with OOo 3.2.0 JA/DEB on Ubuntu 9.10 i386
henrich_d: ok to me...please see the screen shot I attached. I installed OOo_3.2.0_LinuxIntel_install_ja_deb.tar.gz on Ubuntu 9.10 i386. . thanks
maho, did you test it with slideshow? Just show it is okay to me with Debian unstable, Fedora 13 alpha and Ubuntu 10.04 beta but slideshow is wrong.
1) open boldfont-with-japanese-font.odp with Impress 2) press F5 key 3) I see this issue
maho is right, I'm wrong. OOo_3.2.0_LinuxIntel_install_ja_deb.tar.gz works fine, so it's distros' package issue.
Ok, thanks. Then I will close it as works for me...
Closed. Thanks everyone for helping.
I also checked the slideshow. I cannot reproduce.
it seems a bit complicated problem. cf. http://lists.freedesktop.org/archives/ooo-build/2010-April/000781.html and thorsten's reply would be informative. http://lists.freedesktop.org/archives/ooo-build/2010-April/000787.html ------------------------------------------- Kohei Yoshida wrote: > As it turns out, the bold VL Gothic font gets multiplied as in the above > screenshot (look closely at the "Testcase" text) *only when* the > hardware acceleration is turned on, and it happens *only when* the font > is VL Gothic and you are in slideshow mode. > > Looks like it's your area, Thorsten? :-) > Yep, seems cairocanvas is causing this. We're directly using cairo to render the glyphs there, seems there's a bug. For quickest processing, would be good to have this filed on bugzilla.novell.com.

Work around for this CJK "double bold" in slideview mode problem happened on 003.2 on Ubuntu 10.04 is to uncheck the "hardware acceleration" (tools->option->view) https://bugs.launchpad.net/openoffice/+bug/585910
Upstream OOo does not use cairo canvas as default but this can easily change -> reopening
and reassigning
Reset assigne to the default "issues@openoffice.apache.org".
