Flags for buffer_t.

Fields

class buffer_flags_t

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.

DEFAULT

The default buffer flag.

DEFINED

All currently defined flags: Since: 4.4.0

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

EOT

Flag indicating that special handling of the end of text paragraph can be applied to this buffer, similar to HB_BUFFER_FLAG_BOT.

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.

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

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

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

VERIFY

Flag indicating that the 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
