[Libreoffice-bugs] [Bug 157348] Bad font rendering with 7.5 and higher because freetype interpreter-version is ignored
https://bugs.documentfoundation.org/show_bug.cgi?id=157348 --- Comment #15 from Frank Steiner --- There is no need to do that as the reason for this changed rendering has become clear in the meantime. After asking at the developers list I was pointed to the file vcl/unx/generic/gdi/cairotextrender.cxx After anaylzing the code it is obvious that as long as one cannot disable subpixel positioing in cairo (and there seems to be no way to do that in Linux) the code enforces CAIRO_HINT_STYLE_SLIGHT as hint style if it has been set to MEDIUM or FULL by the user. But for rendering Microsoft fonts like Arial in their thin version one needs either CAIRO_HINT_STYLE_MEDIUM or CAIRO_HINT_STYLE_FULL. This can be set in Linux via ~/.Xresources, using "Xft.hinting: hintmedium/hintfull" (fontconfig will not work for this), but the code in cairotextrender.cxx reverts it to hintslight, and that causes Arial etc. to become bolder. So, either there has to be a way to disable subpixel positioning in Linux, or the LO code must be changed to accept the users choice of hintmedium/hintfull. I asked on the list if devs might consider to change the code accordingly to allow the user to choose the hinting style again (is was before 7.5.x) but didn't get an answer yet. -- You are receiving this mail because: You are the assignee for the bug.

https://bugs.documentfoundation.org/show_bug.cgi?id=157348 --- Comment #11 from Frank Steiner --- Just realized that it also depends on your fontconfig settings. On my system, a file in in /etc/fonts/conf.d set the autohint mode to "false" for Arial. When I change that to true, Arial looks bold even with interpreter-version=35. So, the sharper and leaner display for Arial (and all other MS fonts and Anonymous Pro) is used only with autohinter disabled and interpreter-version=35 Maybe Libreoffice > 7.4.7 has decided to enforce autohinter mode to all truetype fonts no matter what the fontconfig settings are? -- You are receiving this mail because: You are the assignee for the bug.

https://bugs.documentfoundation.org/show_bug.cgi?id=157348 --- Comment #10 from Frank Steiner --- I just tested with the 7.4.7 you can download from https://www.libreoffice.org/download/download-libreoffice/ Anyway, the effect is way more visible with the microsoft fonts, so maybe your distro has a package for fetching those. "fetchmsttfonts" on opensuse or ttf-mscorefonts-installer on ubuntu for example. -- You are receiving this mail because: You are the assignee for the bug.

So I can't compare it with the present state. Hopefully someone else is able to do it. -- You are receiving this mail because: You are the assignee for the bug.

https://bugs.documentfoundation.org/show_bug.cgi?id=157348 --- Comment #6 from Frank Steiner --- It shows with all Microsoft fonts (Andale, Arial, Times New Roman etc.), that we use most of the time due to the exchange of documents with our Windows users. Apart from those I've found only one other font: /usr/share/fonts/truetype/AnonymousPro-Regular.ttf which is from google-anonymouspro-fonts.rpm. This font can be downloaded either from https://www.marksimonson.com/fonts/view/anonymous-pro or from https://fonts.google.com/specimen/Anonymous+Pro, and although the font files are different in both downloads, they look the same. The difference between interpreter version 35 and 40 is not as remarkable as with the Microsoft fonts, but it is visible, see apro.png Hope that helps! -- You are receiving this mail because: You are the assignee for the bug.

https://bugs.documentfoundation.org/show_bug.cgi?id=157348 --- Comment #4 from Frank Steiner --- Sorry, I messed things up trying to attach the first attachment while opening the bug. Please ignore the " Libreoffice 7.4.7, interpreter-version 35" attachment, it shows the wrong file. The three correct attachments are: Libreoffice 7.4.7, interpreter-version 35 (correct version): This shows how arial font looks like with FREETYPE_PROPERTIES="truetype:interpreter-version=35". You can see that the font is slim and that's how it used to be in all versions before 7.5.6. Libreoffice 7.4.7, interpreter-version 40: That's how aria looks like with FREETYPE_PROPERTIES="truetype:interpreter-version=40". Too bold for our users, that's why we've been using the interpreter-version=35 for years. Libreoffice 7.5.6, interpreter-version 35 and 40: In LO 7.5.6 and 7.6.1 arial looks like this, no matter if FREETYPE_PROPERTIES is set to interpreter-version=35 or 40. So there is no way to get the slim version of many fonts back. These bolder fonts really don't look nice to our users in most of our documents, so it would be great if libreoffice could restore support for the FREETYPE_PROPERTIES="truetype:interpreter-version=35" setting. -- You are receiving this mail because: You are the assignee for the bug.
