Justification engine demo

[dberlow]

As more and more needs to be demonstrated at once, before we go too far in parametric x space, I'd like to specify parametric y space more definitively.

So, e.g. pictured below, it's hard to look at larger samples in the justification demo (left) (typetools right), because the linespacing is not following an ideal:

So, can we automate all linespacing, at least in the Justification engine, to a single function like this:

then we can tweaque it for things like widths, and weights after we tweaque it for size.

Using YOPQ makes it serif/sans and case independent, as using YOPQ, means justifying using the local YOPQ value exactly, or to leverage off it and get a proper linespacing

Let me know thanks.

Okay I have added this math! And some new labels at the top of the paragraph that shows the current YOPQ, column width, and line height.

Todo: make column width a slider, or detect touch events to make it work on mobile.

Chris, There is one thing i hope we can do easily and quickly. I'd like to be able to compose and justify RobotoExtremo, as well as AmstelvarAlpha?

Yes it should be straightforward. Do you have a set of acceptable ranges against size/weight like we did previously?

We will find out shortly;)

...From applying the same ones we are using Amstelvar

This was more work than expected because a lot of the code was based around the assumption that Amstelvar Alpha was the center of the universe. I've loosened up the justification demo page to be more font-agnostic. I put in some initial values for Roboto Extremo, using wdth since it doesn't have XTRA. My eyeball says my values are probably a bit too extreme, but it's a start.

You can edit the Roboto tolerances here if you like.

[dberlow]

Oops. Robotodelta has the paramedics not extremo....

Do we have composite-to-parametric relationship math for Roboto Delta? (For doing the ghost-slider thing in typetools, and for computing relative-weight based on XOPQ for the brochure.) @sannorozco @dberlow

[ghost]

Okay Delta is in on the Justification page
