I want to use the fonts in an Epub3 in fixed format and Epub3 only allow OTF and WOFF fonts. So I want to see font type in Adobe Fonts and I can't find how to do that. Do you know how to see font type in Adobe fonts?
I know that Poppins is an TTF font since I use it in my printed book, but the Epub3 validation tool does not allow TTF-fonts.
If you have to upload separate font files Adobe Fonts won't work for such purposes since it doesn't store individual font files that are visible in the computer's file system. The data is somewhat hidden. You won't find things like OTF files in any file folders using Windows File Explorer or the Finder on a Mac.
The Adobe Fonts web site doesn't display font formats other than static, variable and color. When I'm using Adobe's desktop applications, such as Illustrator, any fonts synced via Adobe Fonts will typically have an OpenType symbol listed next to them in the font menu. I see the same thing in some rival graphics applications.
There are third party applications, such as TransType 4, than can convert TrueType fonts into OpenType format.
I'm not an expert on EPUB 3 or coding references to fonts in web pages. I don't know if the methods people use to code Adobe Fonts into web sites will work with EPUB 3. Google Fonts offers embed code for HTML at its site. Does it not point to WOFF web font files?
