Subject Re: Using a font licensed under Apache License, version 2.0 in commercial vector artworks
Date Sun, 08 May 2016 01:22:32 GMT

Just my take, not an expert. I'll let others chip in.

If you are using the font to produce graphics (bitmap or vector), then you
are not redistributing the Apache-licensed font. I would say this is not
even making a derivative work, unless your graphic is basically every
letter of the alphabet in all font weights and styles.

Fonts are weird - they are a bit like a picture, but also a bit like a
program, as they include rules for tweaking their appearance depending on
letter combinations and font sizes.

The Apache license does not apply to the outcome of running an
Apache-licensed program. However it does apply to the object form, so if
you redistribute the fonts in any format, the license would apply, e.g. if
you embed the fonts in a PDF.

Nevertheless, provided the author has not given a NOTICE file you need to
propagate, then there is no requirement of attribution in the "object
form", only "source form" (e.g. if you make a new, derived font) would need
to include such.

The only requirement then, say for the PDF case where you embed the font
file, is to include the Apache license, I believe you can do that using the
metadata of the format. Note that the Apache license is not "viral" and
does not have to apply to your part of the derived work.
