Today's applications must support high-quality text rendering, resolution-independent outline fonts, and full Unicode text and layout support. DirectWrite, a DirectX API, provides these features and more.
- A device-independent text layout system that improves text readability in documents and in UI.
- High-quality, sub-pixel, Microsoft ClearType text rendering that can use GDI, Direct2D, or application-specific rendering technology.
- Hardware-accelerated text, when used with Direct2D.
- Support for multi-format text.
- Support for the advanced typography features of OpenType fonts.
- Support for the layout and rendering of text in all supported languages.
- GDI-compatible layout and rendering.
The API supports measuring, drawing, and hit-testing of multi-format text. DirectWrite handles text in all supported languages for global and localized applications, building on the key language infrastructure found in Windows 7. DirectWrite also provides a low-level glyph rendering API for developers who want to perform their own layout and Unicode-to-glyph processing.
Project Reunion introduces a new version of DirectWrite—called DWriteCore—that runs on versions of Windows down to Windows 8, and opens the door for you to use it cross-platform. For more details, see DWriteCore overview.
- Windows 7 or Windows Vista with Service Pack 2 (SP2) and Platform Update for Windows Vista
- Windows Server 2008 R2 or Windows Server 2008 with Service Pack 2 (SP2) and Platform Update for Windows Server 2008
