https://fedoraproject.org/wiki/Changes/ProvideOpenTypeBitmapFonts == Summary == This proposal plans to provide some additional popular bitmap fonts in OpenType format to use with pango. By providing some bitmap fonts from BDF/PCF format to OpenType format, applications like gnome-terminal can continue to use some bitmap fonts with the pango 1.44 package. == Owner == * Name: [[User:pwu| Peng Wu]] * Email: pwu@xxxxxxxxxx * Name: [[User:tagoh| Akira Tagoh]] * Email: tagoh@xxxxxxxxxx == Detailed Description == In Fedora 31, pango has been upgraded to 1.44, and switched to use the HarfBuzz library instead of FreeType. But HarfBuzz doesn't support bitmap fonts or Adobe Type 1 fonts. In gnome-terminal, the bitmap fonts can't be used. In order to use the bitmap fonts with pango 1.44, we propose to provide some additional popular bitmap fonts in OpenType format by using fonttosfnt tool. The bitmap font in OpenType format will be contained in new sub package. User can choose to install the bitmap font either in legacy format or OpenType format from different sub packages. We plan to provide 5-10 bitmap fonts in OpenType format in some packages. The current font candidates are bitmap-lucida-typewriter-fonts, terminus-fonts and ucs-miscfixed-font. == Benefit to Fedora == Some popular bitmap fonts are used by many users. After providing the bitmap fonts in OpenType format, users can continue to use the bitmap fonts in gnome-terminal, etc. == Scope == * Proposal owners: Fonts SIG * Other developers: N/A (not a System Wide Change) * Release engineering: [https://pagure.io/releng/issues/9130 Releng issue 9130] * Policies and guidelines: N/A (not a System Wide Change) * Trademark approval: N/A (not needed for this Change) == Upgrade/compatibility impact == N/A (not a System Wide Change) == How To Test == N/A (not a System Wide Change) == User Experience == After converting the bitmap fonts, users will be able to use the popular bitmap fonts again with pango 1.44 in gnome-terminal, etc. The OpenType bitmap fonts should have the similar shape for each glyph, compared with the original bitmap fonts. == Dependencies == N/A (not a System Wide Change) == Contingency Plan == * Contingency mechanism: N/A (not a System Wide Change) * Contingency deadline: N/A (not a System Wide Change) == Release Notes == In Fedora 32, we provide bitmap fonts with modern font format (OpenType Bitmap Font) to use with gnome-terminal and other applications which uses pango for font rendering. -- Ben Cotton He / Him / His Fedora Program Manager Red Hat TZ=America/Indiana/Indianapolis _______________________________________________ devel mailing list -- devel@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to devel-leave@xxxxxxxxxxxxxxxxxxxxxxx Fedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/ List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/devel@xxxxxxxxxxxxxxxxxxxxxxx
