Implementations

impl<'a> Os2<'a>

pub fn version(&self) -> u16

pub fn x_avg_char_width(&self) -> i16

Average weighted escapement.

The Average Character Width parameter specifies the arithmetic average of the escapement (width) of all non-zero width glyphs in the font.

pub fn us_weight_class(&self) -> u16

Weight class.

Indicates the visual weight (degree of blackness or thickness of strokes) of the characters in the font. Values from 1 to 1000 are valid.

pub fn us_width_class(&self) -> u16

Width class.

Indicates a relative change from the normal aspect ratio (width to height ratio) as specified by a font designer for the glyphs in a font.

pub fn fs_type(&self) -> u16

Type flags.

Indicates font embedding licensing rights for the font.

pub fn y_subscript_x_size(&self) -> i16

pub fn y_subscript_y_size(&self) -> i16

The recommended vertical size in font design units for subscripts for this font.

pub fn y_subscript_x_offset(&self) -> i16

The recommended horizontal offset in font design units for subscripts for this font.

pub fn y_subscript_y_offset(&self) -> i16

The recommended vertical offset in font design units for subscripts for this font.

pub fn y_superscript_x_size(&self) -> i16

The recommended horizontal size in font design units for superscripts for this font.

pub fn y_superscript_y_size(&self) -> i16

The recommended vertical size in font design units for superscripts for this font.

pub fn y_superscript_x_offset(&self) -> i16

The recommended horizontal offset in font design units for superscripts for this font.

pub fn y_superscript_y_offset(&self) -> i16

The recommended vertical offset in font design units for superscripts for this font.

pub fn y_strikeout_size(&self) -> i16

Thickness of the strikeout stroke in font design units.

pub fn y_strikeout_position(&self) -> i16

The position of the top of the strikeout stroke relative to the baseline in font design units.

pub fn s_family_class(&self) -> i16

Font-family class and subclass. This parameter is a classification of font-family design.

PANOSE classification number.

Additional specifications are required for PANOSE to classify non-Latin character sets.

Unicode Character Range.

Unicode Character Range (bits 0-31).

pub fn ul_unicode_range_2(&self) -> u32

Unicode Character Range (bits 32-63).

pub fn ul_unicode_range_3(&self) -> u32

Unicode Character Range (bits 64-95).

pub fn ul_unicode_range_4(&self) -> u32

Unicode Character Range (bits 96-127).

pub fn ach_vend_id(&self) -> Tag

Font Vendor Identification.

The four-character identifier for the vendor of the given type face.

pub fn fs_selection(&self) -> SelectionFlags

Font selection flags.

Contains information concerning the nature of the font patterns.

pub fn us_first_char_index(&self) -> u16

pub fn s_typo_descender(&self) -> i16

The typographic descender for this font.

pub fn s_typo_line_gap(&self) -> i16

The typographic line gap for this font.

pub fn us_win_ascent(&self) -> u16

The “Windows ascender” metric.

This should be used to specify the height above the baseline for a clipping region.

pub fn us_win_descent(&self) -> u16

The “Windows descender” metric.

This should be used to specify the vertical extent below the baseline for a clipping region.

pub fn us_break_char(&self) -> Option<u16>

his is the Unicode code point, in UTF-16 encoding, of a character that can be used as a default break character.
