@cluster: the index of the character in the original text that corresponds
to this #hb_glyph_info_t, or whatever the client passes to
hb_buffer_add(). More than one #hb_glyph_info_t can have the same
@cluster value, if they resulted from the same character (e.g. one
to many glyph substitution), and when more than one character gets
merged in the same glyph (e.g. many to one glyph substitution) the
#hb_glyph_info_t will have the smallest cluster value of them.

-
hb_buffer_flags_t
-
hb_buffer_flags_t:
@HB_BUFFER_FLAG_DEFAULT: the default buffer flag.
@HB_BUFFER_FLAG_BOT: flag indicating that special handling of the beginning
of text paragraph can be applied to this buffer. Should usually
be set, unless you are passing to the buffer only part
of the text without the full context.
@HB_BUFFER_FLAG_EOT: flag indicating that special handling of the end of text
paragraph can be applied to this buffer, similar to
@HB_BUFFER_FLAG_BOT.
@HB_BUFFER_FLAG_PRESERVE_DEFAULT_IGNORABLES:
flag indication that character with Default_Ignorable
Unicode property should use the corresponding glyph
from the font, instead of hiding them (done by
replacing them with the space glyph and zeroing the
advance width.) This flag takes precedence over
@HB_BUFFER_FLAG_REMOVE_DEFAULT_IGNORABLES.
@HB_BUFFER_FLAG_REMOVE_DEFAULT_IGNORABLES:
flag indication that character with Default_Ignorable
Unicode property should be removed from glyph string
instead of hiding them (done by replacing them with the
space glyph and zeroing the advance width.)
@HB_BUFFER_FLAG_PRESERVE_DEFAULT_IGNORABLES takes
precedence over this flag. Since: 1.8.0
@HB_BUFFER_FLAG_DO_NOT_INSERT_DOTTED_CIRCLE:
flag indicating that a dotted circle should
not be inserted in the rendering of incorrect
character sequences (such at <0905 093E>). Since: 2.4.0
@HB_BUFFER_FLAG_VERIFY:
flag indicating that the hb_shape() call and its variants
should perform various verification processes on the results
of the shaping operation on the buffer. If the verification
fails, then either a buffer message is sent, if a message
handler is installed on the buffer, or a message is written
to standard error. In either case, the shaping result might
be modified to show the failed output. Since: 3.4.0
@HB_BUFFER_FLAG_PRODUCE_UNSAFE_TO_CONCAT:
flag indicating that the @HB_GLYPH_FLAG_UNSAFE_TO_CONCAT
glyph-flag should be produced by the shaper. By default
it will not be produced since it incurs a cost. Since: 4.0.0
@HB_BUFFER_FLAG_PRODUCE_SAFE_TO_INSERT_TATWEEL:
flag indicating that the @HB_GLYPH_FLAG_SAFE_TO_INSERT_TATWEEL
glyph-flag should be produced by the shaper. By default
it will not be produced. Since: 5.1.0
@HB_BUFFER_FLAG_DEFINED: All currently defined flags: Since: 4.4.0
-
hb_buffer_serialize_flags_t
-
hb_buffer_serialize_flags_t:
@HB_BUFFER_SERIALIZE_FLAG_DEFAULT: serialize glyph names, clusters and positions.
@HB_BUFFER_SERIALIZE_FLAG_NO_CLUSTERS: do not serialize glyph cluster.
@HB_BUFFER_SERIALIZE_FLAG_NO_POSITIONS: do not serialize glyph position information.
@HB_BUFFER_SERIALIZE_FLAG_NO_GLYPH_NAMES: do no serialize glyph name.
@HB_BUFFER_SERIALIZE_FLAG_GLYPH_EXTENTS: serialize glyph extents.
@HB_BUFFER_SERIALIZE_FLAG_GLYPH_FLAGS: serialize glyph flags. Since: 1.5.0
@HB_BUFFER_SERIALIZE_FLAG_NO_ADVANCES: do not serialize glyph advances,
glyph offsets will reflect absolute glyph positions. Since: 1.8.0.
Note: when this flag is used with a partial range of the buffer (i.e.
@start is not 0), calculating the absolute positions has a cost
proportional to @start. If the buffer is serialized in many small
chunks, this can lead to quadratic behavior. It is recommended to
use a larger @buf_size to minimize this cost.
@HB_BUFFER_SERIALIZE_FLAG_DEFINED: All currently defined flags. Since: 4.4.0
-
hb_buffer_serialize_format_t
-
hb_buffer_serialize_format_t:
@HB_BUFFER_SERIALIZE_FORMAT_TEXT: a human-readable, plain text format.
@HB_BUFFER_SERIALIZE_FORMAT_JSON: a machine-readable JSON format.
@HB_BUFFER_SERIALIZE_FORMAT_INVALID: invalid format.
-

-
hb_direction_t:
@HB_DIRECTION_INVALID: Initial, unset direction.
@HB_DIRECTION_LTR: Text is set horizontally from left to right.
@HB_DIRECTION_RTL: Text is set horizontally from right to left.
@HB_DIRECTION_TTB: Text is set vertically from top to bottom.
@HB_DIRECTION_BTT: Text is set vertically from bottom to top.
-
hb_draw_line_cap_t
-
hb_draw_line_cap_t:
@HB_DRAW_LINE_CAP_BUTT: No cap; the line ends exactly at
its endpoint.
@HB_DRAW_LINE_CAP_SQUARE: Square cap; the line is extended
past its endpoint by half the local stroke width. Useful
for composing closed shapes from line segments (e.g. a
rectangle made from four lines).
-
hb_glyph_flags_t
-
hb_glyph_flags_t:
@HB_GLYPH_FLAG_UNSAFE_TO_BREAK: Indicates that if input text is broken at the
beginning of the cluster this glyph is part of,
then both sides need to be re-shaped, as the
result might be different.
On the flip side, it means that when this
flag is not present, then it is safe to break
the glyph-run at the beginning of this
cluster, and the two sides will represent the
exact same result one would get if breaking
input text at the beginning of this cluster
and shaping the two sides separately.
This can be used to optimize paragraph
layout, by avoiding re-shaping of each line
after line-breaking.
@HB_GLYPH_FLAG_UNSAFE_TO_CONCAT: Indicates that if input text is changed on one
side of the beginning of the cluster this glyph
is part of, then the shaping results for the
other side might change.
Note that the absence of this flag will NOT by
itself mean that it IS safe to concat text.
Only two pieces of text both of which clear of
this flag can be concatenated safely.
This can be used to optimize paragraph
layout, by avoiding re-shaping of each line
after line-breaking, by limiting the
reshaping to a small piece around the
breaking position only, even if the breaking
position carries the
#HB_GLYPH_FLAG_UNSAFE_TO_BREAK or when
hyphenation or other text transformation
happens at line-break position, in the following
way:

for HarfBuzz, so HarfBuzz may modify the data.
@HB_MEMORY_MODE_READONLY_MAY_MAKE_WRITABLE: See above
-
hb_ot_color_palette_flags_t
-
hb_ot_color_palette_flags_t:
@HB_OT_COLOR_PALETTE_FLAG_DEFAULT: Default indicating that there is nothing special
to note about a color palette.
@HB_OT_COLOR_PALETTE_FLAG_USABLE_WITH_LIGHT_BACKGROUND: Flag indicating that the color
palette is appropriate to use when displaying the font on a light background such as white.

@HB_PAINT_COMPOSITE_MODE_SRC_ATOP: draw source on top of destination content and
only there
@HB_PAINT_COMPOSITE_MODE_DEST: ignore the source
@HB_PAINT_COMPOSITE_MODE_DEST_OVER: draw destination on top of source
@HB_PAINT_COMPOSITE_MODE_DEST_IN: leave destination only where there was
source content (unbounded)
@HB_PAINT_COMPOSITE_MODE_DEST_OUT: leave destination only where there was no
source content
@HB_PAINT_COMPOSITE_MODE_DEST_ATOP: leave destination on top of source content
and only there (unbounded)
@HB_PAINT_COMPOSITE_MODE_XOR: source and destination are shown where there is only
one of them
@HB_PAINT_COMPOSITE_MODE_PLUS: source and destination layers are accumulated
@HB_PAINT_COMPOSITE_MODE_MULTIPLY: source and destination layers are multiplied.
This causes the result to be at least as dark as the darker inputs.
@HB_PAINT_COMPOSITE_MODE_SCREEN: source and destination are complemented and
multiplied. This causes the result to be at least as light as the lighter
inputs.
@HB_PAINT_COMPOSITE_MODE_OVERLAY: multiplies or screens, depending on the
lightness of the destination color.
@HB_PAINT_COMPOSITE_MODE_DARKEN: replaces the destination with the source if it
is darker, otherwise keeps the source.
@HB_PAINT_COMPOSITE_MODE_LIGHTEN: replaces the destination with the source if it
is lighter, otherwise keeps the source.
@HB_PAINT_COMPOSITE_MODE_COLOR_DODGE: brightens the destination color to reflect
the source color.
@HB_PAINT_COMPOSITE_MODE_COLOR_BURN: darkens the destination color to reflect
the source color.
@HB_PAINT_COMPOSITE_MODE_HARD_LIGHT: Multiplies or screens, dependent on source
color.
@HB_PAINT_COMPOSITE_MODE_SOFT_LIGHT: Darkens or lightens, dependent on source
color.
@HB_PAINT_COMPOSITE_MODE_DIFFERENCE: Takes the difference of the source and
destination color.
@HB_PAINT_COMPOSITE_MODE_EXCLUSION: Produces an effect similar to difference, but
with lower contrast.
@HB_PAINT_COMPOSITE_MODE_HSL_HUE: Creates a color with the hue of the source
and the saturation and luminosity of the target.
@HB_PAINT_COMPOSITE_MODE_HSL_SATURATION: Creates a color with the saturation
of the source and the hue and luminosity of the target. Painting with
this mode onto a gray area produces no change.
@HB_PAINT_COMPOSITE_MODE_HSL_COLOR: Creates a color with the hue and saturation
of the source and the luminosity of the target. This preserves the gray
levels of the target and is useful for coloring monochrome images or
tinting color images.
@HB_PAINT_COMPOSITE_MODE_HSL_LUMINOSITY: Creates a color with the luminosity of
the source and the hue and saturation of the target. This produces an
inverse effect to @HB_PAINT_COMPOSITE_MODE_HSL_COLOR.

hb_paint_extend_t
-
hb_paint_extend_t:
@HB_PAINT_EXTEND_PAD: Outside the defined interval,
the color of the closest color stop is used.
@HB_PAINT_EXTEND_REPEAT: The color line is repeated over
repeated multiples of the defined interval
@HB_PAINT_EXTEND_REFLECT: The color line is repeated over
repeated intervals, as for the repeat mode.
However, in each repeated interval, the ordering of
color stops is the reverse of the adjacent interval.

hb_style_tag_t
-
hb_style_tag_t:
@HB_STYLE_TAG_ITALIC: 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.
@HB_STYLE_TAG_OPTICAL_SIZE: Used to vary design to suit different text sizes.
Non-zero. Values can be interpreted as text size, in points.
@HB_STYLE_TAG_SLANT_ANGLE: 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)
@HB_STYLE_TAG_SLANT_RATIO: same as @HB_STYLE_TAG_SLANT_ANGLE expression as ratio.
Typical right-leaning Italic fonts have a positive slant ratio (typically around 0.2)
@HB_STYLE_TAG_WIDTH: 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.
@HB_STYLE_TAG_WEIGHT: 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.

hb_subset_flags_t
-
hb_subset_flags_t:
@HB_SUBSET_FLAGS_DEFAULT: all flags at their default value of false.
@HB_SUBSET_FLAGS_NO_HINTING: If set hinting instructions will be dropped in
the produced subset. Otherwise hinting instructions will be retained.
@HB_SUBSET_FLAGS_RETAIN_GIDS: If set glyph indices will not be modified in
the produced subset. If glyphs are dropped their indices will be retained
as an empty glyph.
@HB_SUBSET_FLAGS_DESUBROUTINIZE: If set and subsetting a CFF font the
subsetter will attempt to remove subroutines from the CFF glyphs.
@HB_SUBSET_FLAGS_NAME_LEGACY: If set non-unicode name records will be
retained in the subset.
@HB_SUBSET_FLAGS_SET_OVERLAPS_FLAG: If set the subsetter will set the
OVERLAP_SIMPLE flag on each simple glyph.
@HB_SUBSET_FLAGS_PASSTHROUGH_UNRECOGNIZED: If set the subsetter will not
drop unrecognized tables and instead pass them through untouched.
@HB_SUBSET_FLAGS_NOTDEF_OUTLINE: If set the notdef glyph outline will be
retained in the final subset.
@HB_SUBSET_FLAGS_GLYPH_NAMES: If set the PS glyph names will be retained
in the final subset.
@HB_SUBSET_FLAGS_NO_PRUNE_UNICODE_RANGES: If set then the unicode ranges in
OS/2 will not be recalculated.
@HB_SUBSET_FLAGS_NO_LAYOUT_CLOSURE: If set do not perform glyph closure on layout
substitution rules (GSUB). Since: 7.2.0.
@HB_SUBSET_FLAGS_OPTIMIZE_IUP_DELTAS: If set perform IUP delta optimization on the
remaining gvar table's deltas. Since: 8.5.0
@HB_SUBSET_FLAGS_NO_BIDI_CLOSURE: If set do not pull mirrored versions of input
codepoints into the subset. Since: 11.1.0
@HB_SUBSET_FLAGS_IFTB_REQUIREMENTS: If set enforce requirements on the output subset
to allow it to be used with incremental font transfer IFTB patches. Primarily,
this forces all outline data to use long (32 bit) offsets. Since: EXPERIMENTAL
@HB_SUBSET_FLAGS_RETAIN_NUM_GLYPHS: If this flag is set along side
HB_SUBSET_FLAGS_RETAIN_GIDS then the number of glyphs in the font won't
be reduced as a result of subsetting. If necessary empty glyphs will be
included at the end of the font to keep the number of glyphs unchanged.
@HB_SUBSET_FLAGS_DOWNGRADE_CFF2: If set and instantiating a variable font,
convert the output CFF2 table to CFF1. This enables compatibility with older
renderers that don't support CFF2. Since: 13.0.0
