% Support code for direct use of TrueType fonts.

% Note that if you want to use this file without including the ttfont.dev

% files before this one:
%	lib/gs_mgl_e.ps
%	lib/gs_mro_e.ps

% ---------------- Automatic Type 42 generation ---------------- %

% Load a TrueType font from a file as a Type 42 PostScript font.
% The thing that makes this really messy is the handling of encodings.
% There are 2 interacting tables that affect the encoding:
%       'cmap' provides multiple maps from character codes to glyph indices
%       'post' maps glyph indices to glyph names (if present)
% What we need to get out of this is:
%       Encoding mapping character codes to glyph names
%         (the composition of cmap and post)
%       CharStrings mapping glyph names to glyph indices
%         (the inverse of post)
% If the post table is missing, we have to take a guess based on the cmap
% table.

% neg2 is number of segments x 2. A format 4 cmap, with usable
    % mappings cannot (according to the spec) have only 1 segment,
    % since format 4 requires a closing segment with start and end
    % codes being 0xffff. Unfortunately, we have found badly subsetted
    % TTF fonts which have one segment with valid mappings, and no
    % closing segment.
    % In such a case, force the loop to work as though as we have two
    % segments - this works as we don't rely on the terminating segment
    % but use the loop counter to spot completion - effrectively, we
    % ignore the closing segment when it's present, anyway.
    %
    % This loop and/or putglyph do not account for out of spec fonts
    % that have repeated or overlapping ranges in the segments. As we
    % write the code/gid to a PS dictionary, later encounters with a
    % given code will overwrite the earlier one(s). As this is outside
    % of the spec, it's not clear how other consumers handle this
    % condition, so we'll await a suitable example before making changes.
    % Two choices are: drop later repeated/overlapping segments entirely,
    % or only use codes from later, overlapping segments not already set
    % by the earlier segment. (Inspired by Bug 700968).
    % Revision: bug 703589 has an (invalid) cmap table with overlapping
    % (actually repeating) ranges, and requires the *first* range definition
    % to be used in order to render correctly. So /putglyph now refuses to
