INTRODUCTION

APCA CONTRAST FONT LOOKUP TABLES Copyright © 2022 by Myndex Research and Andrew Somers. All Rights Reserved

Public Beta 0.1.7 (G) • MAY 28 2022

• NOTES: These new arrays have a few more elements in them, to facilitate the new multi-use-case conformance concept, wherein different use cases have (essentially) different lookups.

• On the SAPC site, this is demonstrated: the score array provides the adjustment factor, applied to the base font lookup table, as needed for different use cases.

A few additional elements were added to accommodate a new use-case conformance method.

These arrays are in their natural sort order. The natural sort order then is ascending for font size and weight, And that then correlates with a descending contrast array.

However, if sorted to ascending, then Lc 45 * 0.2 = 9 and 9 is the index for the row for Lc 45
