# Taken from “Example 1: A contextal substituation table” in
|
||
# https://developer.apple.com/fonts/TrueType-Reference-Manual/RM06/Chap6morx.html
|
||
# as retrieved on 2017-09-05.
|
||
#
|
||
# Compared to the example table in Apple’s specification, we’ve
|
||
# made the following changes:
|
||
#
|
||
# * at offsets 0..35, we’ve prepended 36 bytes of boilerplate
|
||
# to make the data a structurally valid ‘morx’ table;
|
||
#
|
||
# * at offset 36 (offset 0 in Apple’s document), we’ve changed
|
||
# the number of glyph classes from 5 to 6 because the encoded
|
||
# finite-state machine has transitions for six different glyph
|
||
# classes (0..5);
|
||
#
|
||
# * at offset 52 (offset 16 in Apple’s document), we’ve replaced
|
||
# the presumably leftover ‘XXX’ mark by an actual data offset;
|
||
#
|
||
# * at offset 72 (offset 36 in Apple’s document), we’ve changed
|
||
# the input GlyphID from 51 to 52. With the original value of 51,
|
||
# the glyph class lookup table can be encoded with equally many
|
||
# bytes in either format 2 or 6; after changing the GlyphID to 52,
|
||
# the most compact encoding is lookup format 6, as used in Apple’s
|
||
# example;
|
||
#
|
||
# * at offset 90 (offset 54 in Apple’s document), we’ve changed
|
||
# the value for the lookup end-of-table marker from 1 to 0.
|
||
# Fonttools always uses zero for this value, whereas Apple’s
|
||
# spec examples are inconsistently using one of {0, 1, 0xFFFF}
|
||
# for this filler value;
|
||
#
|
||
# * at offset 172 (offset 136 in Apple’s document), we’ve again changed
|
||
# the input GlyphID from 51 to 52, for the same reason as above.
|
||
#
|
||
# TODO: Ask Apple to fix “Example 1” in the ‘morx’ specification.

# Taken from “Example 2: A ligature table” in
|
||
# https://developer.apple.com/fonts/TrueType-Reference-Manual/RM06/Chap6morx.html
|
||
# as retrieved on 2017-09-11.
|
||
#
|
||
# Compared to the example table in Apple’s specification, we’ve
|
||
# made the following changes:
|
||
#
|
||
# * at offsets 0..35, we’ve prepended 36 bytes of boilerplate
|
||
# to make the data a structurally valid ‘morx’ table;
|
||
#
|
||
# * at offsets 88..91 (offsets 52..55 in Apple’s document), we’ve
|
||
# changed the range of the third segment from 23..24 to 26..28.
|
||
# The hexdump values in Apple’s specification are completely wrong;
|
||
# the values from the comments would work, but they can be encoded
|
||
# more compactly than in the specification example. For round-trip
|
||
# testing, we omit the ‘f’ glyph, which makes AAT lookup format 2
|
||
# the most compact encoding;
|
||
#
|
||
# * at offsets 92..93 (offsets 56..57 in Apple’s document), we’ve
|
||
# changed the glyph class of the third segment from 5 to 6, which
|
||
# matches the values from the comments to the spec (but not the
|
||
# Apple’s hexdump).
|
||
#
|
||
# TODO: Ask Apple to fix “Example 2” in the ‘morx’ specification.
