FontStretch Structure

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

Visual Basic (Declaration)

Public Structure FontStretch

public struct FontStretch

XAML Attribute Usage

<object property="fontStretchesPropertyName"/>

XAML Values

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

The FontStretch type exposes the following members.

Methods

	Name	Description
	Equals	Compares an object with the current FontStretch object. (Overrides ValueType..::.Equals(Object).)
	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.)
	GetHashCode	Retrieves the hash code for this object. (Overrides ValueType..::.GetHashCode()()().)
	GetType	Gets the Type of the current instance. (Inherited from Object.)
	MemberwiseClone	Creates a shallow copy of the current Object. (Inherited from Object.)
	ToString	Creates a String representation of the current FontStretch object. (Overrides ValueType..::.ToString()()().)

Operators

	Name	Description
	Equality	Compares two instances of FontStretch for equality.
	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.

FontStretches Static Property Names

Font stretch	usWidthClass	% of normal
UltraCondensed	1	50.0%
ExtraCondensed	2	62.5%
Condensed	3	75.0%
SemiCondensed	4	87.5%
Normal	5	100%
SemiExpanded	6	112.5%
Expanded	7	125.0%
ExtraExpanded	8	150.0%
UltraExpanded	9	200.0%

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.
