FontStretch Structure

Microsoft Silverlight will reach end of support after October 2021. Learn more.

Describes the degree to which a font has been stretched, compared to the normal aspect ratio of that font.

Namespace:  System.Windows
Assembly:  System.Windows (in System.Windows.dll)

Syntax

'Declaration
Public Structure FontStretch
public struct FontStretch
<object property="fontStretchesPropertyName"/>

XAML Values

    A FontStretches static property name, such as Condensed, Normal, or Expanded.

The FontStretch type exposes the following members.

Methods

  Name Description
Public methodSupported by Silverlight for Windows Phone Equals Compares an object with the current FontStretch object. (Overrides ValueType.Equals(Object).)
Protected methodSupported by Silverlight for Windows Phone Finalize Allows an object to try to free resources and perform other cleanup operations before the Object is reclaimed by garbage collection. (Inherited from Object.)
Public methodSupported by Silverlight for Windows Phone GetHashCode Retrieves the hash code for this object. (Overrides ValueType.GetHashCode().)
Public methodSupported by Silverlight for Windows Phone GetType Gets the Type of the current instance. (Inherited from Object.)
Protected methodSupported by Silverlight for Windows Phone MemberwiseClone Creates a shallow copy of the current Object. (Inherited from Object.)
Public methodSupported by Silverlight for Windows Phone ToString Creates a String representation of the current FontStretch object. (Overrides ValueType.ToString().)

Operators

Public operatorStatic memberSupported by Silverlight for Windows Phone Equality Compares two instances of FontStretch for equality.
Public operatorStatic memberSupported by Silverlight for Windows Phone Inequality Evaluates two instances of FontStretch to determine inequality.

Remarks

A font stretch describes the degree to which a font form is stretched from its normal aspect ratio, which is the original width to height ratio specified for the glyphs in the font.

This structure provides compatibility between Silverlight and WPF properties that specify a font stretch. The compatibility requirement is that in Silverlight 1.0, the relevant properties reference FontStretch, which is an enumeration, whereas WPF relevant properties referenced FontStretches, a class with static properties.

FontStretch is the value type for Silverlight properties or attributes that specify a font stretches value, but you must use static properties of FontStretches to provide a FontStretch value. In XAML, you specify the name of a FontStretches property as the attribute value. This functionality is enabled by native XAML parsing behavior that processes the string value.

Medium is also an accepted string value for XAML and type conversion, and evaluates to the same value as Normal, but Medium does not exist as a static property and therefore cannot be specified in code.

The FontStretches values correspond to the usWidthClass definition in the OpenType specification. The usWidthClass represents an integer value between 1 and 9—lower values indicate narrower widths; higher values indicate wider widths.
