We use harfbuzz, a third party OpenType shaping engine for OpenType features support. I do not see any reference to the "salt" tag in harfbuzz code, so I can only conclude that stylistic alternates are at that moment not supported by harfbuzz. So at that point we have no reason to add such control to the text properties palette. |
|
|
I have submitted a request in harfbuzz to support salt feature. https://github.com/harfbuzz/harfbuzz/issues/694 |
|
|
well, salt feature is supported by harfbuzz. |
|
|
Well, we would need to know how to get the number of stylistic alternates then. |
|
|
HarfBuzz will working for this. https://github.com/harfbuzz/harfbuzz/issues/673 If HarfBuzz get the implementation, then we can do it. Also we can fix 0014885 as well |

well, this bug & let me think about font features GUI in scribus, it isn't possible to implement all opentype features in GUI. Right now there is 140 features and more to come. Libreoffice solution is smart and do the job. Read this doc about it: http://www.scholarsfonts.net/Using_OT_in_LibreOffice_1-2.pdf what about if we implement advance font feature text field where you can enter the font feature you want to apply to the text. This will save space and target advance users only. By this we will pass font feature directly to Harfbuzz. |

> what about if we implement advance font feature text field where you can enter the font feature you want to apply to the text. This will save space and target advance users only. By this we will pass font feature directly to Harfbuzz. I agree with you, that is what Inkscape does anyway. But I think we can also make the interface awesome if HarfBuzz implement this new API. |
