Video Terminal Screen Version 3 - 10/30/92 Copyright (c) 1991-1992 E A BEHL PostScript Type 1 and TrueType Typeface A monospaced, pixel-based, IBM-PC character set typeface. General Description ------------------- Video Terminal Screen (VTS) resembles characters of a data terminal or text on an EGA/VGA monitor of a personal computer. Video Terminal Screen was designed for use as a text font for technical documents such as software programming manuals. The character set is monospaced, so that text captured from an actual data session can be imported directly into a document with minimal touch up. The Video Terminal Screen typeface family consists of three font files which make available all 253 characters of the IBM-PC character set (there are no characters associated with ASCII 00, 32, or 255). The base (or roman) font file contains all 253 characters, although standard encoding of PostScript Type 1 and TrueType font files do not allow convenient access to all characters. To make access to the full character set more convenient, two other files are included, which are identified as the italic and boldface members of the family. The italic file contains the lower 31 characters remapped upward by 64 character positions and the Greek and math characters remapped down by 128 character positions. The boldface file contains the box characters remapped down 128 character positions. Background Information ---------------------- Typical of monospaced fonts, Video Terminal Screen is somewhat short and "squatty." The character set is based on the "standard" 8x16 pixel character set of EGA/VGA card character generators. For the sake of simplicity and memory consumption, each character is an outline of the EGA/VGA pixel pattern. Each pixel is a simple square. Character spacing is provided primarily by virtue of the characters using only the first seven columns of pixels, ensuring that adjacent text characters are separated by at least one pixel width. In this way, when box and graphic characters (which use all eight pixel columns) appear adjacent to each other, they meet to form continuous lines. Using the VTS Family -------------------- The Video Terminal Screen typeface family is designed to conveniently provide full access to the entire IBM-PC character set. Using only the base font file in Microsoft Windows 3.1 or later, all characters in the set from ASCII 33 through ASCII 254 are available, using Alt key combinations for characters above ASCII 127. However, if the more obscure characters are needed out of the set, either or both of the additional font files may be necessary. The 31 symbol characters from ASCII 01 to 31 in the IBM-PC correspond to the ASCII characters Control-A through Control-_. The italic font file contains these characters, shifted up 64 positions. For instance, the open smiley face character, which corresponds to Control-A in the IBM-PC, may be printed by typing an upper case A in Video Terminal Screen, then switching the character to italic. The italic font file also contains the Greek/math symbols from ASCII 224 through 254, shifted down 128 positions, so that typing a grave accent (the key with the tilde) in italic produces the Greek alpha symbol. For convenience, the 48 box and geometric characters from ASCII 176 through 223, which appear in their normal positions in the base font file, also are contained in the boldface font file shifted down by 128 positions. This allows typing the characters from 0 (zero) to the underscore character, then switching to boldface, to produce the box characters without using Alt key combinations. This may be useful when Alt key combinations are not allowed, or in non-Windows applications.
