Video Display of Italics And Bold Character Fonts

This article describes a simple, inexpensive way to display characters representing italic or bold characters on a video display terminal (VDT). The VDT must be able to provide single dotting, 1.5 dotting and double dotting.

The character set to be displayed is stored in a character generator. If a normal or base character is to be displayed by the VDT, 1.5 dots are displayed for each position in the stored character representation. Italics characters are represented on the VDT by displaying a single dot for each character position. Bold characters are represented on the VDT by double dotting each character position. The single dotted representation simulates the thin strokes of an italic character while the double dotted representation simulates the thick strokes of a bold character.

This technique can be used instead of storing separate fonts for base, italic and bold characters. The character to be displayed in a particular VDT screen location is completely identified by designating the character and by assigning an attribute word to the screen location. Two bits in an attribute word can indicate which of the three possible fonts is to be displayed at that location.
