Struct directwrite::enums::FontWeight

#[repr(transparent)]
pub struct FontWeight(pub u32);

Represents the density of a typeface, in terms of the lightness or heaviness of the strokes. The enumerated values correspond to the usWeightClass definition in the OpenType specification. The usWeightClass represents an integer value between 1 and 999. Lower values indicate lighter weights; higher values indicate heavier weights.

Weight differences are generally differentiated by an increased stroke or thickness that is associated with a given character in a typeface, as compared to a "normal" character from that same typeface. The following illustration shows an example of Normal and UltraBold weights for the Palatino Linotype typeface.

Note Not all weights are available for all typefaces. When a weight is not available for a typeface, the closest matching weight is returned.

Font weight values less than 1 or greater than 999 are considered invalid, and they are rejected by font API functions.
