|
|
Here is the introduction of OpenType variation, some related technical documents are also available on this page: https://www.microsoft.com/typography/otspec/otvaroverview.htm |
|
|
Some variable fonts are ready for test https://github.com/Monotype/Monotype_prototype_variable_fonts/ https://github.com/TypeNetwork/fb-Decovar https://github.com/TypeNetwork/fb-Amstelvar https://github.com/googlei18n/noto-fonts-alpha/tree/master/from-pipeline/unhinted/variable-ttf |
|
|
PDF does not support OpenType font variations. At this point such font would have to be converted to outlines. |
|
|
The page you linked even specify this explicitly: "In certain application workflows, it may be necessary to dynamically generate a static font resource for a particular instance — that is, conventional, non-variation font tables that use interpolated values for a particular instance. This may be needed in order to provide font data to legacy software or data formats that do not understand or support variable fonts, such as legacy printer drivers, or PDF or XPS files with embedded font data. " |

|
>> PDF does not support OpenType font variations. At this point such font would have to be converted to outlines. OK, so we need to create a conveter for OT Variation instance when necessary. |
|
|
Both Illustrator and Photoshop CC 2018 added support for OT font variation, and they are providing graphical interface for this. See: https://helpx.adobe.com/illustrator/using/fonts.html https://helpx.adobe.com/photoshop/using/fonts.html |
|
|
Just a question to the one(s) who know better: after nine years, would the font libraries used by Scribus allow to create a subset font (or multiple or...) that can then be embedded in the PDF? |
|
|
One can already subset font and embed in PDF, @ale. I hope I didn't misread your comment. |
|
|
I was specifically referring to variable fonts, which are currently not supported by Scribus. And where subsetting is much more than just removing the unused glyphs. |
