Demo: pwht and pwth #50

Open sberlow opened 6 years ago

@dberlow Can you please describe what this demo should look like

dberlow commented 6 years ago

pwht and pwth are parametrically valued versions of wght and wdth which have OS/2 values, a % and 100-900 respectively.

Demos are at several levels.

  1. the other TN proposed axes have parametric axes, but if weight and width DO NOT have paramentric values, and have to RELY ON wght and wdth for just about anything, then a lot of programability is lost among the other Tn proposed axes, from the beginning.
  2. once pwht and pwth are in the same value system as the rest of our proposal a. programming particular blends of xtra/xtab relative to xopq, within pwdt
    b. programming, or UIing to actual, measured pwht is possible. c. consistently measured pwht across styles of existing families, and across variable families is demonstrable, e.g. give me the parametric weight of Amstelvar regular width, un-italic that's the same as Helvetica Bold Cond. Italic.

You cannot do that with OS/2 values.

Any suggestions on how to demo this with visuals, or shall we just include additional text to describe?

  1. add axes to Amstelvar. (copy and create them from wght and wdth and re-value tp per mille).
  2. Compare a. the match of Amstelvar Regular according to wght, (default 400) to Benton Sans "regular (400) b. the match of Amstelvar Regular according to pwht, to Benton Sans "regular" with a pwht assigned according to the same measure.
