4. Variable components
2. Feature axes
“1” in Adam's post is demonstrated clearly with Both of the Goggle fonts we made. Amstelvar’s Registered axes Are Defined by carefully adjusting the Parametric Axes to the desired instances of opsz, max & min, wght, max & min and wdth opsz, max & min, instances which were then instantiated as TTFs and added to the ttv as the regisered axes.
The typography intended from Decovar is un-expressible without a format, or application UI addition, to define thousands of axes via something other than instances in the space.
I explained that about both of these fonts in Berlin, but even before that, others pointed out how wasteful it is to store all those instances, (as is the case in Amstelvar), or leave the user in a stylistic wilderness of sliders, (as is the case in Decovar), if one could store the coordinates, reduce the number of sliders and replace a lot of futzing with programmable variable space.
Our proposal was niether funded, nor inclined under the circumstances, to ask for changes, any changes, to the font format. It was funded to propose how to define the axes for the global typographic requirements of 2018.
That’s going along just fine, thanks.
Dave is right, “2”, “3” and “4” are in our proposal. It is just a proposal for how it would be great to work. I don’t see another way to achieve what must be achieved in the spec, though implementing what we propose in our tools is a no-brainer. You?
On the other hand, what you’ve written, an axis for each feature? is not only going to make people freak right out, but it’s not explained, tooled or demonstrated. Perhaps you should do this excercise completely, Adam — you see the proposals, perhaps Make, Show and Tell us all how the Uppercase axis works!?, for certainly:
if axes are needing to be feature-specific, then there would have to be an Uppercase axis,
Or is there something about the Uppercase that says it does not need a registered axis in your plan, thanks.
