DirectWrite

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. Windows App SDK 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.
