buffer_serialize_flags_t#

Added in version 0.9.20.

class buffer_serialize_flags_t#

Flags that control what glyph information are serialized in buffer_serialize_glyphs().

Fields#

class buffer_serialize_flags_t

DEFAULT#: Serialize glyph names, clusters and positions.

DEFINED#: All currently defined flags. Since: 4.4.0

GLYPH_EXTENTS#: Serialize glyph extents.

GLYPH_FLAGS#: Serialize glyph flags. Since: 1.5.0

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.

NO_CLUSTERS#: Do not serialize glyph cluster.

NO_GLYPH_NAMES#: Do no serialize glyph name.

NO_POSITIONS#: Do not serialize glyph position information.
