Status: RESOLVED FIXED

(Core :: Graphics: Text, task, P2)

Description

[Ryan VanderMeulen [:RyanVM]]

+++ This bug was initially created as a clone of Bug #1636963 +++

We already picked up the security fix that drove the 2.10.4 release, but here's the list of changes for 2.10.3.

CHANGES BETWEEN 2.10.2 and 2.10.3

I. IMPORTANT CHANGES

• New flag `FT_OUTLINE_OVERLAP'. If set, make the smooth rasterizer
  do 4x4 oversampling to mitigate artifacts in pixels partially
  covered by overlapping contours. Note that this at least
  quadruples the rendering time.

  If a glyph in a TrueType font has the OVERLAP_SIMPLE' orOVERLAP_COMPOUND' bit set, FreeType automatically selects this
  rendering mode.

II. MISCELLANEOUS

• Using the arcane method of including FreeType header files with
  macros like `FT_FREETYPE_H' is no longer mandatory (but retained
  as an optional feature for backward compatibility).

• Support for building the library with Meson. Building the demo
  programs with Meson will follow in a forthcoming release.

• Minor improvements to the B/W rasterizer.

• Auto-hinter support for Medefaidrin script.

• Fix various memory leaks (mainly for CFF) and other issues that
  might cause crashes in rare circumstances.

• Jam support has been removed.

• In ftview', custom LCD filter values are now normalized and balanced. Unorthodox filters are still available through the-L'
  command line option.

• The GUI demo programs can now be resized.

• Demo programs that accept command line option `-k' can now handle
  function keys, too. The corresponding character codes start with
  0xF1. As an example, the POSIX shell syntax (accepted by bash,
  ksh, and zsh)

  -k $'\xF3q'

  emulates the pressing of function key F3' followed by keyq'.
