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: PresentationCore (in PresentationCore.dll)

Syntax

Visual Basic

<TypeConverterAttribute(GetType(FontStretchConverter))> _
<LocalizabilityAttribute(LocalizationCategory.None)> _
Public Structure FontStretch _
    Implements IFormattable

[TypeConverterAttribute(typeof(FontStretchConverter))]
[LocalizabilityAttribute(LocalizationCategory.None)]
public struct FontStretch : IFormattable

Visual C++

[TypeConverterAttribute(typeof(FontStretchConverter))]
[LocalizabilityAttribute(LocalizationCategory::None)]
public value class FontStretch : IFormattable

[<Sealed>]
[<TypeConverterAttribute(typeof(FontStretchConverter))>]
[<LocalizabilityAttribute(LocalizationCategory.None)>]
type FontStretch =

XAML Attribute Usage

XAML Values

fontStretchesValue: A FontStretches value expressed as the name string, such as "Condensed", "Normal", or "Expanded".

The FontStretch type exposes the following members.

Methods

	Name	Description
	Compare	Compares two instances of FontStretch objects.
	Equals(FontStretch)	Compares a FontStretch object with the current FontStretch object.
	Equals(Object)	Compares a 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 it is reclaimed by garbage collection. (Inherited from Object.)
	FromOpenTypeStretch	Creates a new instance of FontStretch that corresponds to the OpenType usStretchClass value.
	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.)
	ToOpenTypeStretch	Returns a value that represents the OpenType usStretchClass for this FontStretch object.
	ToString	Creates a String representation of the current FontStretch object based on the current culture. (Overrides ValueType..::.ToString()()().)

Operators

	Name	Description
	Equality	Compares two instances of FontStretch for equality.
	GreaterThan	Evaluates two instances of FontStretch to determine if one instance is greater than the other.
	GreaterThanOrEqual	Evaluates two instances of FontStretch to determine whether one instance is greater than or equal to the other.
	Inequality	Evaluates two instances of FontStretch to determine inequality.
	LessThan	Evaluates two instances of FontStretch to determine whether one instance is less than the other.
	LessThanOrEqual	Evaluates two instances of FontStretch to determine whether one instance is less than or equal to the other.

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.

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.

Font stretch	usWidthClass	% of normal
UltraCondensed	1	50.0%
ExtraCondensed	2	62.5%
Condensed	3	75.0%
SemiCondensed	4	87.5%
Medium	5	100.0%
SemiExpanded	6	112.5%
Expanded	7	125.0%
ExtraExpanded	8	150.0%
UltraExpanded	9	200.0%

For more information on the OpenType usWidthClass value, see the "Font File Tables" section of the OpenType specification.
