Bug 1779123

LibreOffice already dropped Type 1 support for the same reasons several years ago

And it produced the same kind of user pushback.

And in the end, no one did anything, probably because our stash of OpenType vector fonts is rich enough nowadays, no one found it worth his time to rescue Type 1 fonts.

#bug 1753295 is quite different, because the user population here, is composed of people who have been resisting migration to vector fonts for at least 25 years (and, because they didn't want to use vector fonts ever at all, have been deliberately buying low resolution screens that work for bitmap fonts but not vector fonts).

Would you please refrain from spreading the same user bashing in yet another bug?

This bug is specifically for documenting the need for a transition from type1 fonts to opentype fonts and the tools in Fedora (or absence thereof) to do so.

You seem to claim there is no way to convert type1 fonts to opentype. Do I understand that correctly? In this case, the lack of type1 font support in Fedora 31 (which comes at no surprise to you) is something that needs to be documented, like any major incompatible change in functionality, surprising to some or not.

The transition from Type 1 already happened years ago while you were not looking. 

Thanks to TEX Gyre, and LibreOffice dropping Type1 support, and years of work by many people, including myself, including documentation work.

The main Fedora application that uses vector fonts, LibreOffice, deprecated them in version 5.3, so that makes it a Fedora 26 change (6 releases ago)

Bitmap is a special last-redoubt case. It’s not a generic font situation, no matter how much you want to make it.

As for conversion to OpenType, CFF OpenType (OTF) was specifically designed to allow Adobe converting its large store of Type1 fonts to OpenType without data loss (the outline format within OTF is pretty much the same as within Type 1 fonts).

So Type 1 conversion is mostly opening up Type 1 font files in fontforge, fix the font metadata (all the metadata available or strictly specified in OpenType, that were missing or badly specified in Type 1, and saving the result as OTF.

Since a lot of real-world fonts have garbage in their metadata fields all that matters practically is fixing the naming fields ie apply OpenType Name ID 16/17 rules instead of reporting the limitations of Type1 naming in OpenType

TEX Gyre took a lot more work than that because the project was not just converting legacy Type1 fonts, it was fixing and extending them.

Keep issueing personal accusations and get flagged.

LibreOffice is not Fedora's only font consumer - by far it is not. In fact, everything depending on pango/harfbuzz supported type1 up to and including Fedora 30. That is the whole point why users should be informed before the upgrade F30 -> F31.

Which Type 1 font should I try to convert?

Maybe makeotf from Adobe Font Development Kit for OpenType is one option.
