v2.32.3

• coloured is a synonym of the option colored in pattern definition.

• fix a bug related to pdf page resources in dvi mode

• users can access the lua table containing mplib instances luamplib.instances,
  through which metapost variables are also easily accessible as documented in
  LuaTeX manual 11.2.8.4.

v2.32.2

fix matrix conversion between MP and PDF

v2.32.1

• for the sake of convenience, width and height values of tiling patterns will be written down into the log file.
• table type is allowed as well as string type for matrix and bbox options in pattern definition.
• metapost code such as rotated 30 slanted .2 is allowed as well as the string or table of numbers for the matrix option in pattern definition.
• as for the resources option in pattern definition, luamplib automatically includes the resources of the current page.
• luamplib does not log info even if there's no beginfig ... endfig.

v2.32.0

• \mppattern{<name>} ... \endmppattern defines a tiling pattern which can be used with withpattern operator to fill a closed path by replicating the tile horizontally and vertically. \begin{mppattern} ... \end{mppattern} is exactly the same as \mppattern ... \endmppattern. See luamplib manual for details.

v2.31.2

• support vertical writing mode in mpliboutlinetext
  (presently luatexko package only, and except horizontal mode inside vertical mode)
• after the process of mpliboutlinetext, mpliboutlinepic[1] ... mpliboutlinepic[mpliboutlinenum] will be preserved as an array of images each of which containing a glyph or a rule. N.B. Unicode grapheme cluster is not considered here.

v2.31.1

• fix bugs in outlinetext routine
• improve rule treatment in graphictext

v2.31.0

• provide a new metapost operator mpliboutlinetext, which mimicks metafun's outlinetext. The syntax is the same as metafun's. (#133)

v2.30.0

• provide a new metapost operator mplibglyph, which returns a metapost
  picture containing outline paths of a glyph in opentype, truetype or type1
  fonts. When a type1 font is specified, metapost primitive glyph will be
  called. In the syntax as follows, subfont number is zero based.

   mplibglyph 50   of \fontid\font            % slot 50 of current font
   mplibglyph 50   of "cmr10"                          % type1 font
   mplibglyph "Q"  of "TU/TeXGyrePagella(0)/m/n/10"    % TeX fontname
   mplibglyph "똠" of "NotoSansCJKkr-Regular.otf"      % raw filename
   mplibglyph "Q"  of "Times.ttc(2)"                   % subfont number
   mplibglyph "똠" of "SourceHanSansK-VF.otf[Regular]" % instance name
  

• provide a new metapost command mplibdrawglyph. In contrast to metapost's
  draw command, this one fills paths of a picture according to the Nonzero
  Winding Number Rule.

• in mplibgraphictext, option scale is deprecated and now a synonym of
  scaled. In DVI mode, unicode-math package is needed for math formula
  graphictext.

v2.29.0

• provide new TeX macros to reduce typing toil. \mpfig ... \endmpfig is roughly the abbreviation of

         \begin{mplibcode}[@mpfig]
         beginfig(0)
         token list declared by \everymplib[@mpfig]
         ...
         token list declared by \everyendmplib[@mpfig]
         endfig;
         \end{mplibcode}

and \mpfig* ... \endmpfig is roughly the abbreviation of

         \begin{mplibcode}[@mpfig]
         ...
         \end{mplibcode}

These macros are protected and unexpandable. In these macros \mpliblegacybehavior{false} is forcibly declared. As both share the same instance name, MetaPost codes are inherited among them. The instance name (default: @mpfig) can be changed by redefining \mpfiginstancename.

• instance names are allowed in plain TeX as well. The syntax is:

         \mplibcode[name] ... \endmplibcode
         \everymplib[name]{ ... }
         \everyendmplib[name]{ ... }

These macros are now protected and unexpandable.

• provide new MetaPost operators mplibtexcolor and mplibrgbtexcolor which convert TeX color expressions to MetaPost color expressions. The latter one forces rgb model results (#112). For instance,

         mplibtexcolor "olive"     % => (0, 0, 1, 0.5)
         mplibrgbtexcolor "olive"  % => (0.5, 0.5, 0)

As spot colors are always forced to cmyk or rgb model, it is not recommended to use these operators for them.

• write down MetaPost messages into the log file

v2.28.2

• direction of figure box is explicitly declared as TLT (#129)
• figure box materials are emitted in one go at the end of the figure
  (to enable tex.runtoks in spot color shading routine)
