== 特性 ==
* 全面支持[[Unicode]]，超过20个脚本提供Windows支持的每种语言的布局和渲染。DirectWrite支持多格式文本的测量、渲染和{{tsl|en|Hit-testing|命中测试}}。{{TransH}}支持Unicode特性，包括[[雙向文稿|BIDI]]、line breaking, surrogates, UVS, language-guided script itemization, number substitution, and glyph shaping.{{TransF}}
* 有双向[[反鋸齒]]的子像素[[ClearType]]文本渲染可以与GDI/GDI+、[[Direct2D]]/[[Direct3D]]和任何应用程序的特定技术互操作。在使用Direct2D时，文字渲染可以硬件加速，或者可以在硬件加速不可用时使用{{tsl|en|Windows Advanced Rasterization Platform|WARP软件光栅化器}}.
* 支持[[OpenType]]支持高级印刷特性，例如文体交替和{{tsl|en|Swash (typography)||花饰}}，这从未在GDI和[[Windows Forms|WinForms]]中支持。这些功能在2008年[[专业开发者大会]]的DirectWrite推出时使用{{tsl|en|Gabriola (typeface)|Gabriola字体}}演示，本身也引入了Windows 7。<ref>{{Cite web|url=http://channel9.msdn.com/Blogs/pdc2008/PC18|title=Windows 7: Introducing Direct2D and DirectWrite – pdc2008|date=29 October 2008|work=Channel 9|publisher=Microsoft|accessdate=2017-05-26|archive-date=2011-06-30|archive-url=https://web.archive.org/web/20110630233825/http://channel9.msdn.com/blogs/pdc2008/pc18|dead-url=no}}</ref>
* 为采用专有文字布局和Unicode到字形处理的案例提供底层字形渲染API。
在[[Windows 8.1]]中，DirectWrite开始支持[[OpenType|彩色字体]]。<ref>{{Cite web|url=https://msdn.microsoft.com/en-us/library/windows/desktop/hh802480(v=vs.85).aspx|title=What's new in DirectWrite|work=Microsoft Developer Network|publisher=Microsoft|accessdate=2017-05-26|archive-date=2017-07-14|archive-url=https://web.archive.org/web/20170714182301/https://msdn.microsoft.com/en-us/library/windows/desktop/hh802480(v=vs.85).aspx|dead-url=no}}</ref><ref>{{Cite web|url=http://channel9.msdn.com/Events/Build/2013/3-191|title=Innovations in High Performance 2D Graphics with DirectX – Build 2013|author=Dan McLachlan|date=26 June 2013|work=Channel 9|publisher=Microsoft|accessdate=2017-05-26|archive-date=2016-12-29|archive-url=https://web.archive.org/web/20161229185017/https://channel9.msdn.com/Events/Build/2013/3-191|dead-url=no}}</ref>
