% KERNDICT a PostScript dictionary for automatical kerning %
% written by Thomas Baruchel (may 2003) %
% %
% Several methods are provided %
% * Tangent-based kerning (an idea of the author) %
% 45° tangents encapsulate the letter at the right or at the left. %
% How far they are from the left or right side of the BoundingBox %
% tells what can be done. The method is intended to be very quick. %
% Usage : { kernproc } (Hello) kshow %
% %
% * Sector-based kerning (a classical method) %
% The user chooses the length of the smallest horizontal gap %
% between the two letters. The number of sectors gives the %
% precision of the computation. %
% Usage : { 175 12 kernsector } (Hello) kshow %
% Warning : not intended to take account of spaces %
% %
% * Outline-based kerning %
% The user chooses the real distance between the characters even %
% if the two closest points of the outline are not at the same %
% height. The user must build an outline version of the font he %
% uses before calling the procedure. The /StrokeWidth key of this %
% outline font must be set to the expected distance. A number of %
% sectors give the precision of the computation. %
% Usage : { /Outline-Font findfont 12 kernoutline } (Hello) kshow %
% Warning : not intended to take account of spaces %
