- A computer font is an electronic data file(Data can be stored in Two forms Text and Binary) containing a set of glyphs, characters or symbols such as dingbats.
There are three basic kinds of computer font file.
- Bitmap : This fonts consists of a matrix of dots or pixels representing the image of each face and size.
- Outline : Fonts also called as vector fonts use Bezier curves, drawing instructions and mathematical formulae to describe each glyph, which make the character outlines scalable to any size
- Stroke : Fonts use a series of specified lines and additional information to define the profile, or size and shape of the line in a specific face, which together describe the appearance of the glyph.
- Font files contain one or more fonts that can be accessed by the operating system and applications.
- Most modern fonts are stored in either the open Type or True Type formats, which can be used by both macintosh and windows computers.
- Common font file extension include .OTF, .TTF and .FNT.
- .OTF : An OTF file is a font format developed by Adobe and Microsoft. It combines aspects of Postscript and True Type font formats and is fully scalable, meaning the font can be resized without losing quality.
- .TTF : A TTF file is a font file format created by Apple, but used on both Macintosh and windows platforms.
- .FNT : An FNT file is a font file used by the windows operating system and often saved within the system fonts directory. It stores a generic font and may include vector and raster glyphs. FNT files have largely been replaced by TrueType(.TTF) and OpenType(.OTF) fonts.
