XAML Values

fontStretchesValue

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

The FontStretch type exposes the following members.

  NameDescription
Public methodStatic memberCompareCompares two instances of FontStretch objects.
Public methodEquals(FontStretch)Compares a FontStretch object with the current FontStretch object.
Public methodEquals(Object)Compares a Object with the current FontStretch object. (Overrides ValueType.Equals(Object).)
Protected methodFinalizeAllows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.)
Public methodStatic memberFromOpenTypeStretchCreates a new instance of FontStretch that corresponds to the OpenType usStretchClass value.
Public methodGetHashCodeRetrieves the hash code for this object. (Overrides ValueType.GetHashCode().)
Public methodGetTypeGets the Type of the current instance. (Inherited from Object.)
Protected methodMemberwiseCloneCreates a shallow copy of the current Object. (Inherited from Object.)
Public methodToOpenTypeStretchReturns a value that represents the OpenType usStretchClass for this FontStretch object.
Public methodToStringCreates a String representation of the current FontStretch object based on the current culture. (Overrides ValueType.ToString().)

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.
