Editing TrueType (section)

===Adoption by Microsoft===
To ensure its wide adoption, Apple licensed TrueType to Microsoft for free.<ref>{{cite web|last=Gassée|first=Jean-Louis|title=The Adobe&nbsp;– Apple Flame War|url=http://www.mondaynote.com/2010/04/11/the-adobe-apple-flame-war/|date=11 April 2010|website=mondaynote.com|access-date=10 November 2011|archive-url=https://web.archive.org/web/20111230022744/http://www.mondaynote.com/2010/04/11/the-adobe-apple-flame-war/ |archive-date=30 December 2011}}</ref> Microsoft added TrueType into the [[Windows 3.1]] operating environment. In partnership with their contractors, [[Monotype Imaging]], Microsoft put a lot of effort into creating a set of high quality TrueType fonts that were compatible with the core fonts being bundled with PostScript equipment at the time. This included the fonts that are standard with Windows to this day: [[Times New Roman]] (compatible with Times Roman), [[Arial]] (compatible with Helvetica) and [[Courier New]] (compatible with Courier). In this context, "compatible" means two things. On an aesthetic level, it means that the fonts are similar in appearance. On a functional level, it means that the fonts have the same character widths. This allows documents which have been [[typesetting|typeset]] in one font to be changed to the other, without [[Reflowable document|reflow]].

Microsoft and Monotype technicians used TrueType's [[Font hinting|hinting]] technology to ensure that these fonts did not suffer from the problem of illegibility at low resolutions, which had previously forced the use of bitmapped fonts for screen display. Subsequent advances in technology have introduced first anti-aliasing, which smooths the edges of fonts at the expense of a slight blurring, and more recently [[subpixel rendering]] (the Microsoft implementation goes by the name [[ClearType]]), which exploits the pixel structure of [[LCD]] based displays to increase the apparent resolution of text. Microsoft has heavily marketed ClearType, and sub-pixel rendering techniques for text are now widely used on all platforms.

Microsoft also developed a "[[smart font]]" technology, named ''TrueType Open'' in 1994, later renamed to [[OpenType]] in 1996 when it merged support of the [[Adobe Inc.|Adobe]] Type 1 glyph outlines. Opentype now contains all of the same functionality of Apple TrueType and Apple TrueType GX.
