Merged 6 years ago by pwu. Opened 6 years ago by mavit.

Use the font we built, rather than the one included with the source.

Prefer zopflipng to optipng, since it should yield smaller files.

mavit commented 6 years ago

There are two changes, here.

A comment in the noto-emoji Makefile says:

zopflipng is better (about 5-10%) but much slower. it will be used if present.

I enabled that, but was surprised to find that the resulting RPM delivered exactly the same font. It turns out that, although we were assembling a ttf from the pngs provided, we were immediately overwriting this with the pre-built ttf also included with the source.

The resulting RPM is now 7091927 bytes, versus 7270251 before.
