OpenType fonts
OpenType is a new font file format which has been jointly developed by Adobe Systems Inc. and
Microsoft Corporation. It is an extension of the TrueType format: OpenType fonts can contain
TrueType but also Adobe Type 1 font data. This means that you can have an OpenType font based
on:
An Adobe Type 1 font. The file name of such a font has the suffix .otf.
A TrueType font. This font still has the .ttf file name suffix.
You can recognize an OpenType font by the following icons:
OpenType font in Microsoft Windows
