Can be used to speed up reshaping + in line-breaking situations. Essentially, after shaping, it returns + positions in the input string (some of the cluster boundaries) that + are "safe to break" in that if the text is segmented at that position + and two sides reshaped and concatenated, the shaping result is + exactly the same as shaping the text in one piece. + + hb-view and hb-shape and hb-shape now take --verify, which verifies + the above property. + + Some corner cases of the implementation are still not quite working. + Those will be fixed in subsequent releases. + +- New API: + +hb_buffer_append() + +hb_glyph_flags_t +HB_GLYPH_FLAG_UNSAFE_TO_BREAK +HB_GLYPH_FLAG_DEFINED +hb_glyph_info_get_glyph_flags() + +HB_BUFFER_SERIALIZE_FLAG_GLYPH_FLAGS + +hb_buffer_diff_flags_t +HB_BUFFER_DIFF_FLAG_EQUAL +HB_BUFFER_DIFF_FLAG_CONTENT_TYPE_MISMATCH +HB_BUFFER_DIFF_FLAG_LENGTH_MISMATCH +HB_BUFFER_DIFF_FLAG_NOTDEF_PRESENT +HB_BUFFER_DIFF_FLAG_DOTTED_CIRCLE_PRESENT +HB_BUFFER_DIFF_FLAG_CODEPOINT_MISMATCH +HB_BUFFER_DIFF_FLAG_CLUSTER_MISMATCH +HB_BUFFER_DIFF_FLAG_GLYPH_FLAGS_MISMATCH +HB_BUFFER_DIFF_FLAG_POSITION_MISMATCH +hb_buffer_diff + + Overview of changes leading to 1.4.8 Tuesday, August 8, 2017 ==================================== diff --git a/configure.ac b/configure.ac index 52134c87..82895eab 100644 --- a/configure.ac +++ b/configure.ac @@ -1,6 +1,6 @@ AC_PREREQ([2.64]) AC_INIT([HarfBuzz], - [1.4.8], + [1.5.0], [https://github.com/behdad/harfbuzz/issues/new], [harfbuzz], [http://harfbuzz.org/]) |
