The lowercase letters seem bold compared to lowercase. -- Configure bugmail: http://bugs.winehq.org/userprefs.cgi?tab=email Do not reply to this email, post in Bugzilla using the above URL to reply. ------- You are receiving this mail because: ------- You are watching all bug changes.

However, I have explained in comment #3 that doing so is pointless in my view because the error lies elsewhere than with rendering of that font. Indeed, running Notepad in Japanese locale and using System font results in this error (uppercase letters thin, lowercase thick) but using Kochi Gothic results in all letters being thin (and somewhat smaller). If you have some insight into the problem that suggests the results of your proposed tests are still useful then stating why it is so would convince me to perform the tests. Also doing so might give the people reading this report more insight into that part of Wine resulting in more accurate future reports. -- Configure bugmail: http://bugs.winehq.org/userprefs.cgi?tab=email Do not reply to this email, post in Bugzilla using the above URL to reply. ------- You are receiving this mail because: ------- You are watching all bug changes.

So the problem with fonts quality is outside of Wine. Both using Freetype with enabled TT bytecode interpreter, and installing Windows CJK fonts will get that 2 things more close to Windows. Although as I said many times even Freetype with enabled TT bytecode interpreter doesn't work very well sometimes, especially with so complex fonts as the CJK ones are. -- Configure bugmail: http://bugs.winehq.org/userprefs.cgi?tab=email Do not reply to this email, post in Bugzilla using the above URL to reply. ------- You are receiving this mail because: ------- You are watching all bug changes.

The latin characters in jvgasys.fon actually look like that, with thick lowercase and thin uppercase letters, with font linking disabled. jvgasys.fon is used as the System font in ja_JP.utf8 locale, in en_* locale vgasys.fon is used as the System font. Wine's built-in System font-linking links System to Tahoma and its fontlinks, but that doesn't override glyphs that appear in the base font. So if you remove all the entries in your FontLinks registry key (eg added by attach 20749) you'll see that the latin characters stay the same, but the Japanese-range characters are reduced to boxes. The actual font appearance difference is due to the ppem value used for jvgasys.fon compared to vgasys.fon. vgasys.fon has a ppem of 16, jvgasys.fon has a ppem of 18. (I don't know what ppem is, see the source of tools/sfnt2fnt for details, and tools/Makefile.in is the file that controls the ppem values used for generating the various .fon files) The ugliness of the font is stated in comment 9 to not be the issue of this bug, but rather the choice of font to use the glyphs from. And that's working correctly. -- Configure bugmail: http://bugs.winehq.org/userprefs.cgi?tab=email Do not reply to this email, post in Bugzilla using the above URL to reply. ------- You are receiving this mail because: ------- You are watching all bug changes.

jvgasys.fon in Wine matches what Windows has. We have a test case in gdi32 which confirms that. As a general rule don't blame Wine if don't have hard facts, do your home work with testing first. -- Configure bugmail: http://bugs.winehq.org/userprefs.cgi?tab=email Do not reply to this email, post in Bugzilla using the above URL to reply. ------- You are receiving this mail because: ------- You are watching all bug changes.

http://bugs.winehq.org/show_bug.cgi?id=18349 --- Comment #14 from Paul "TBBle" Hampson <Paul.Hampson(a)Pobox.com> 2009-05-10 03:55:36 --- "LC_CTYPE=ja_JP.utf8 make font.ok" in build/dlls/gdi32/tests barfs quite badly, while without LC_CTYPE set it passes fine. I guess you mean test_bitmap_font_metrics? It passes with the wine jvgasys.fon, but fails with "font.c:810: Test failed: System(18): tm.tmWeight 400 != 700" with the _Windows_ jvgasys.fon (sourced from Windows XP x64). That's to be expected though, as a comment in the test notes that Wine's Japanese System font has the wrong weight (BOLD instead of NORMAL). And certainly comparing WINEDEBUG=+font for notepad with Wine and Windows jvgasys.fon, I see the following differences: Wine: trace:font:AddFontToList pix_h 18 charset 128 dpi 96x96 pt 14 trace:font:AddFontToList Adding bitmap size h 20 w 8 size 13 x_ppem 18 y_ppem 18 trace:font:OpenFontFace "/home/tbble/code/wine/wine/build-18044/loader/../fonts/jvgasys.fon"/(nil), 0, 18 x 18 trace:font:GetTextMetricsW text metrics: Weight = 700 FirstChar = 32 AveCharWidth = 7 Italic = 0 LastChar = 255 MaxCharWidth = 14 UnderLined = 0 DefaultChar = 128 Overhang = 0 StruckOut = 0 BreakChar = 32 CharSet = 128 PitchAndFamily = 21 -------------------- InternalLeading = 0 Ascent = 16 Descent = 2 Height = 18 Windows: trace:font:AddFontToList pix_h 18 charset 128 dpi 96x96 pt 12 trace:font:AddFontToList Adding bitmap size h 20 w 8 size 12 x_ppem 16 y_ppem 16 trace:font:OpenFontFace "/home/tbble/code/wine/wine/build-18044/loader/../fonts/jvgasys.fon"/(nil), 0, 16 x 16 trace:font:GetTextMetricsW text metrics: Weight = 400 FirstChar = 32 AveCharWidth = 7 Italic = 0 LastChar = 255 MaxCharWidth = 14 UnderLined = 0 DefaultChar = 128 Overhang = 0 StruckOut = 0 BreakChar = 32 CharSet = 128 PitchAndFamily = 01 -------------------- InternalLeading = 0 Ascent = 16 Descent = 2 Height = 18 Note that _both_ log: trace:font:WineEngCreateFontInstance L"System", h=16, it=0, weight=400, PandF=22, charset=128 orient 0 escapement 0 Which suggests at first glance to me that Wine is having to rescale the Wine-built 18pt jvgasys.fon file down to 16pt, while the Windows-source 16pt jvgasys.fon is fine. As to what this means (is jvgasys.fon being generated wrong? Should Wine insist that it's actually 18pt, even if Windows applications expect 16pt System? Something else?) I'm not sure at this point. Interestingly, changing ppem from 18 to 16 in fonts/Makefile.in for jvgasys.fon produces the following: trace:font:AddFontToList pix_h 16 charset 128 dpi 96x96 pt 12 trace:font:AddFontToList Adding bitmap size h 18 w 8 size 12 x_ppem 16 y_ppem 16 and identical trace:font:OpenFontFace and trace:font:GetTextMetricsW results to the Windows jvgasys.fon. It also looks reasonable (although maybe slight small...) Long story short, workaround for this bug is to replace Wine's jvgasys.fon with one from Windows, or one generated with 16ppem instead of 18ppem. They're not fixes though, since although Windows uses 16ppem for its font, its pix_h is the same as Wine's when Wine is at 18ppem. So possibly the font generation or conversion has issues, or some of the mismatched values are due to extra characters in Wine's jvgasys.fon compared to Windows (as mentioned in the gdi32 font.c unit test) -- Configure bugmail: http://bugs.winehq.org/userprefs.cgi?tab=email Do not reply to this email, post in Bugzilla using the above URL to reply. ------- You are receiving this mail because: ------- You are watching all bug changes.
