Enums¶

Data type for holding HarfBuzz’s clustering behavior options. The cluster level dictates one aspect of how HarfBuzz will treat non-base characters during shaping.

In HarfBuzz.buffer_cluster_level_t.MONOTONE_GRAPHEMES, non-base characters are merged into the cluster of the base character that precedes them.

In HarfBuzz.buffer_cluster_level_t.MONOTONE_CHARACTERS, non-base characters are initially assigned their own cluster values, which are not merged into preceding base clusters. This allows HarfBuzz to perform additional operations like reorder sequences of adjacent marks.

HarfBuzz.buffer_cluster_level_t.MONOTONE_GRAPHEMES is the default, because it maintains backward compatibility with older versions of HarfBuzz. New client programs that do not need to maintain such backward compatibility are recommended to use HarfBuzz.buffer_cluster_level_t.MONOTONE_CHARACTERS instead of the default.

New in version 0.9.42.

DEFAULT = 0¶: Default cluster level, equal to HarfBuzz.buffer_cluster_level_t.MONOTONE_GRAPHEMES.

MONOTONE_GRAPHEMES = 0¶: Return cluster values grouped by graphemes into monotone order.

MONOTONE_CHARACTERS = 1¶: Return cluster values grouped into monotone order.

CHARACTERS = 2¶: Don’t group cluster values.

class HarfBuzz.buffer_content_type_t(value)¶

Bases: GObject.GEnum

The type of HarfBuzz.buffer_t contents.

INVALID = 0¶: Initial value for new buffer.

UNICODE = 1¶: The buffer contains input characters (before shaping).

GLYPHS = 2¶: The buffer contains output glyphs (after shaping).

class HarfBuzz.buffer_serialize_format_t(value)¶

Bases: GObject.GEnum

The buffer serialization and de-serialization format used in HarfBuzz.buffer_serialize_glyphs() and HarfBuzz.buffer_deserialize_glyphs().

New in version 0.9.2.

INVALID = 0¶: invalid format.

JSON = 1246973774¶: a machine-readable JSON format.

TEXT = 1413830740¶: a human-readable, plain text format.

class HarfBuzz.direction_t(value)¶

Bases: GObject.GEnum

The direction of a text segment or buffer.

A segment can also be tested for horizontal or vertical orientation (irrespective of specific direction) with HB_DIRECTION_IS_HORIZONTAL() or HB_DIRECTION_IS_VERTICAL().

INVALID = 0¶: Initial, unset direction.

LTR = 4¶: Text is set horizontally from left to right.

TTB = 6¶: Text is set vertically from top to bottom.

BTT = 7¶: Text is set vertically from bottom to top.

class HarfBuzz.memory_mode_t(value)¶

Bases: GObject.GEnum

Data type holding the memory modes available to client programs.

Regarding these various memory-modes:

In no case shall the HarfBuzz client modify memory that is passed to HarfBuzz in a blob. If there is any such possibility, HarfBuzz.memory_mode_t.DUPLICATE should be used such that HarfBuzz makes a copy immediately,
Use HarfBuzz.memory_mode_t.READONLY otherwise, unless you really really really know what you are doing,
HarfBuzz.memory_mode_t.WRITABLE is appropriate if you really made a copy of data solely for the purpose of passing to HarfBuzz and doing that just once (no reuse!),
If the font is mmap()ed, it’s okay to use HarfBuzz.memory_mode_t.READONLY_MAY_MAKE_WRITABLE, however, using that mode correctly is very tricky. Use HarfBuzz.memory_mode_t.READONLY instead.

DUPLICATE = 0¶: HarfBuzz immediately makes a copy of the data.

READONLY = 1¶: HarfBuzz client will never modify the data, and HarfBuzz will never modify the data.

WRITABLE = 2¶: HarfBuzz client made a copy of the data solely for HarfBuzz, so HarfBuzz may modify the data.

READONLY_MAY_MAKE_WRITABLE = 3¶: See above

Bases: GObject.GEnum

Defined by OpenType Design-Variation Axis Tag Registry.

New in version 3.0.0.

SLANT_RATIO = 1399615092¶: same as HarfBuzz.style_tag_t.SLANT_ANGLE expression as ratio. Typical right-leaning Italic fonts have a positive slant ratio (typically around 0.2)

ITALIC = 1769234796¶: Used to vary between non-italic and italic. A value of 0 can be interpreted as “Roman” (non-italic); a value of 1 can be interpreted as (fully) italic.

OPTICAL_SIZE = 1869640570¶: Used to vary design to suit different text sizes. Non-zero. Values can be interpreted as text size, in points.

SLANT_ANGLE = 1936486004¶: Used to vary between upright and slanted text. Values must be greater than -90 and less than +90. Values can be interpreted as the angle, in counter-clockwise degrees, of oblique slant from whatever the designer considers to be upright for that font design. Typical right-leaning Italic fonts have a negative slant angle (typically around -12)

WIDTH = 2003072104¶: Used to vary width of text from narrower to wider. Non-zero. Values can be interpreted as a percentage of whatever the font designer considers “normal width” for that font design.

WEIGHT = 2003265652¶: Used to vary stroke thicknesses or other design details to give variation from lighter to blacker. Values can be interpreted in direct comparison to values for usWeightClass in the OS/2 table, or the CSS font-weight property.
