+ "\n"
+ "The text layout API provides the highest level functionality available from DirectWrite. "
+ "It provides services for the application to measure, display, and interact with richly formatted text strings. "
+ "This text API can be used in applications that currently use Win32 DrawText to build a modern UI with richly formatted text.\n"
+ "\n"
+ "* Text-intensive applications that implement their own layout engine may use the next layer down: the script processor. "
+ "The script processor segments text into runs of similar properties and handles the mapping from Unicode codepoints "
+ "to the appropriate glyph in the font. "
+ "DirectWrite's own layout is built upon this same font and script processing system. "
+ "This sample demonstrates how a custom layout can utilize the information from script itemization, bidi analysis, line breaking analysis, and shaping, "
+ "to accomplish text measurement/fitting, line breaking, basic justification, and drawing.\n"
+ "\n"
+ "The glyph-rendering layer is the lowest layer and provides glyph-rendering functionality for applications "
+ "that implement their own complete text layout engine. The glyph rendering layer is also useful for applications that implement a custom "
+ "renderer to modify the glyph-drawing behavior through the callback function in the DirectWrite text-formatting API.\n"
+ "\n"
+ "The DirectWrite font system is available to all the functional layers, and enables an application to access font and glyph information. "
+ "It is designed to handle common font technologies and data formats. The DirectWrite font model follows the common typographic practice of "
+ "supporting any number of weights, styles, and stretches in the same font family. This model, the same model followed by WPF and CSS, "
+ "specifies that fonts differing only in weight (bold, light, etc.), style (upright, italic, or oblique) or stretch (narrow, condensed, wide, etc.) "
+ "are considered to be members of a single font family.\n"
+ "\n"
+ "Text in DirectWrite is rendered using Microsoft ClearType, which enhances the clarity and readability of text. "
+ "ClearType takes advantage of the fact that modern LCD displays have RGB stripes for each pixel that can be controlled individually. "
+ "DirectWrite uses the latest enhancements to ClearType, first included with Windows Vista with Windows Presentation Foundation, "
+ "that enables it to evaluate not just the individual letters but also the spacing between letters. "
+ "Before these ClearType enhancements, text with a “reading” size of 10 or 12 points was difficult to display: "
+ "we could place either 1 pixel in between letters, which was often too little, or 2 pixels, which was often too much. "
+ "Using the extra resolution in the subpixels provides us with fractional spacing, which improves the evenness and symmetry of the entire page.\n"
+ "\n"
+ "The subpixel ClearType positioning offers the most accurate spacing of characters on screen, "
+ "especially at small sizes where the difference between a sub-pixel and a whole pixel represents a significant proportion of glyph width. "
+ "It allows text to be measured in ideal resolution space and rendered at its natural position at the LCD color stripe, subpixel granularity. "
+ "Text measured and rendered using this technology is, by definition, "
+ "resolution-independent—meaning the exact same layout of text is achieved across the range of various display resolutions.\n"
+ "\n"
+ "Unlike either flavor of GDI's ClearType rendering, sub-pixel ClearType offers the most accurate width of characters. "
+ "The Text String API adopts sub-pixel text rendering by default, which means it measures text at its ideal resolution independent "
+ "to the current display resolution, and produces the glyph positioning result based on the truly scaled glyph advance widths and positioning offsets.";
