Dejavu -> Prop Courrier Sans: add details #4

Open raphaelbastide opened 8 years ago

raphaelbastide commented 8 years ago

Add the type of derivation for DejaVu to Prop Courrier Sans. I think Prop Courrier Sans is based on the metrics of DejaVu right?

Are you sure Not Courier Sans is linked to Dejavu?

celiadzc commented 8 years ago

Actually it's not mentionned in the FONTLOG file. But the gif say that Not Courier Sans is based on the spacing of Dejavu Sans. Prop Courier Sans takes the spacings of Dejavu Sans (found here). Spacing and metrics are 2 differents things, aren't they ? Is it like this : spacing/kerning = space between the letters metrics = ratio height/width (chasse)

raphaelbastide commented 8 years ago

What I understand is:

Not Courier Sans is based on the spacing of Dejavu Sans

Are you sure? Can you provide a screenshot?

celiadzc commented 8 years ago

No I'm not sure, I'm just trying to understand why in the gif it is noted this. fork-me-1413985803-1415567940

Yeah, it is a bit blurry on this gif but I am pretty sure that:
Not Courier Sans + DejaVu’s metrics = Prop Courier Sans

Maybe @rlafuente can confirm?

rlafuente commented 8 years ago

Yes, this is mostly true!

There are many kerning pairs and spacings that we adjusted by hand, so it is not a simple spacing transposition. Additionally, there are some characters that were edited to better fit the proportional design -- punctuation is the most evident example, and there was some trimming to the width of i and l, among other tiny tweaks.

In fact, the first version of PropCourier was not using Dejavu's spacings and was all done by hand, but later we wrote scripts to import spacings in order to make our lives easier.

Just found an updated README with all the necessary info.

The gif looks beautiful! And it's Manufactura btw ;-)

Thank you @rlafuente for those precisions and the README update! The gif is not part of our project, I think Loraine Furter designed it for http://specimen.meteor.com/
