DWRITE_FONT_STRETCH enumeration (dwrite.h)

Represents the degree to which a font has been stretched compared to a font's normal aspect ratio.The enumerated 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.

Syntax

typedef enum DWRITE_FONT_STRETCH {
  DWRITE_FONT_STRETCH_UNDEFINED = 0,
  DWRITE_FONT_STRETCH_ULTRA_CONDENSED = 1,
  DWRITE_FONT_STRETCH_EXTRA_CONDENSED = 2,
  DWRITE_FONT_STRETCH_CONDENSED = 3,
  DWRITE_FONT_STRETCH_SEMI_CONDENSED = 4,
  DWRITE_FONT_STRETCH_NORMAL = 5,
  DWRITE_FONT_STRETCH_MEDIUM = 5,
  DWRITE_FONT_STRETCH_SEMI_EXPANDED = 6,
  DWRITE_FONT_STRETCH_EXPANDED = 7,
  DWRITE_FONT_STRETCH_EXTRA_EXPANDED = 8,
  DWRITE_FONT_STRETCH_ULTRA_EXPANDED = 9
} ;

Constants

DWRITE_FONT_STRETCH_UNDEFINED Value: 0 Predefined font stretch : Not known (0).
DWRITE_FONT_STRETCH_ULTRA_CONDENSED Value: 1 Predefined font stretch : Ultra-condensed (1).
DWRITE_FONT_STRETCH_EXTRA_CONDENSED Value: 2 Predefined font stretch : Extra-condensed (2).
DWRITE_FONT_STRETCH_CONDENSED Value: 3 Predefined font stretch : Condensed (3).
DWRITE_FONT_STRETCH_SEMI_CONDENSED Value: 4 Predefined font stretch : Semi-condensed (4).
DWRITE_FONT_STRETCH_NORMAL Value: 5 Predefined font stretch : Normal (5).
DWRITE_FONT_STRETCH_MEDIUM Value: 5 Predefined font stretch : Medium (5).
DWRITE_FONT_STRETCH_SEMI_EXPANDED Value: 6 Predefined font stretch : Semi-expanded (6).
DWRITE_FONT_STRETCH_EXPANDED Value: 7 Predefined font stretch : Expanded (7).
DWRITE_FONT_STRETCH_EXTRA_EXPANDED Value: 8 Predefined font stretch : Extra-expanded (8).
DWRITE_FONT_STRETCH_ULTRA_EXPANDED Value: 9 Predefined font stretch : Ultra-expanded (9).

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 following illustration shows an example of Normal and Condensed stretches for the Rockwell Bold typeface.

Note  Values other than the ones defined in the enumeration are considered to be invalid, and are rejected by font API functions.
