Inter-Office 1Y1emoranduflI To Cyprians Date January 29) 1976 From Tesler, Merry, Sproull, Lampson, Ingalls location Palo Alto Subject Font Format .Organization PARe XERO)(. This memo explains how we arrived at a font format that is twice as compact as .A L format and is easy to use with l3itI3lt. Backgroufl{} Everybody who ever tried to make the Alto do graphics wondered why there was .no BitBlt, so now there is one, and it is wonderful for moving rectangles around the screen, making gray boxes, and painting. But some of us have been less than delighted with its use for "scan conversion of ll characters.
