Dependency property identifier field: FontStretchProperty

A font stretch describes the degree to which a font form is stretched from its normal aspect ratio. (The aspect ratio is the original width to height ratio specified for the glyphs in the font.) This property can select only from fonts that exist in a font family and the corresponding glyphs. Setting a FontStretch value that does not inherently exist in a font family does not cause programmatic stretching of glyphs. Font fallback behavior does not change the property value, the property will remain as the value you set it to despite whatever visual behavior results due to font fallback.

The FontStretches properties correspond to the usWidthClass definition in the OpenType specification. The usWidthClass represents an integer value between 1 and 9. Lower numeric values indicate narrower widths, and higher values indicate wider widths. For more information about usWidthClass, see the enumeration table in FontStretches.

FontStretch settings for Run child elements override the settings on the containing TextBlock.
