Abstract
Abstract A multiple master typeface can generate and display kanji characters. The graphical elements of the characters in the typeface are classified into shape types, and a glyph set is provided for each shape type. Each glyph set contains base glyphs which represent the variations in the shape type. To generate the character, the shape type of and position of each element in the character is identified. For each element in the character, a weighting factor is determined for each base glyph in the glyph set for the shape type of that element. A composite element is created from the base glyphs in the glyph set for the shape type of that element. The relative contribution of each base glyph to the composite element is determined by the weighting factors determined for that element and that base glyph. To display the character, the composite elements are placed in the identified positions. An instance of a character may be generated from the master characters by interpolating between the master characters on an element by element basis.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
130 words
A method of displaying a master of a digital font character,
comprising: identifying a shape type and a position for each element in
the character; providing a glyph set for each shape type, each glyph set
containing a plurality of different base glyphs; for each element in the character, determining a weighting
factor for each base glyph in the glyph set for the shape type of
that element; for each element in the character, creating a composite
element from the base glyphs in the glyph set for the shape type
of that element, a relative contribution of each base glyph to
the composite element determined by the weighting factors
determined for that element and that base glyph; and placing the composite elements in the identified positions
to display the character.
Claim 2
Dependent Claim
25 words
The method of claim 1, wherein creating a composite
character includes interpolation between the base glyphs in the
glyph set based upon the weighting factors.
Claim 3
Dependent Claim
25 words
The method of claim 1, wherein creating a composite
character includes extrapolation from the base glyphs in the
glyph set based upon the weighting factors.
Claim 4
Dependent Claim
31 words
The method of claim 1, wherein at least one weighting factor
is derived from a weighting value which is assigned to a subset
of the base glyphs in the glyph set.
Claim 5
Dependent Claim
20 words
The method of claim 1, wherein a plurality of weighting
factors are derived from at least one design axis variable.
Claim 6
Dependent Claim
12 words
The method of claim 1 wherein the character is a kanji
character.
Claim 7
Independent Claim
118 words
A method of defining a master of a digital font, comprising: a) identifying a shape type and a position for each element
in a character; b) providing a glyph set for each shape type, each glyph set
containing a plurality of different base glyphs; c) for each element in the character, determining at least
one weighting factor which represents the relative contribution
to a composite element of at least one of the base glyphs in the
glyph set for the shape type of that element; d) storing the shape type, position, and weighting factor
for each element of the character in a non-volatile storage; and e) iterating steps (a) through (d) for each character in the
master font.
Claim 8
Dependent Claim
21 words
The method of claim 7, further comprising iterating steps
(a) through (e) for each master font in a multiple master
typeface.
Claim 9
Dependent Claim
22 words
The method of claim 7, wherein a weighting factor is
determined for each base glyph in the glyph set for each element.
Claim 10
Dependent Claim
25 words
The method of claim 7, wherein the weighting factor
represents the relative contribution of two or more of the base
glyphs to the composite element.
Claim 11
Independent Claim
67 words
A method of generating an instance of a digital font
character, comprising: for each element of a first master character, generating a
first composite element from a first plurality of base glyphs; for each element of a second master character, generating a
second composite element from a second plurality of base glyphs;
and combining the first and second master characters to generate
the instance of the character.
Claim 12
Dependent Claim
25 words
The method of claim 11, wherein for the each element, the
first and second pluralities of base glyphs are selected from the
same glyph set.
Claim 13
Dependent Claim
49 words
The method of claim 12, wherein generating each first
composite element includes defining a first plurality of
weighting factors for each base glyph in the glyph set, and
generating each second composite element includes defining a
second plurality of weighting factors for each base glyph in the
glyph set.
Claim 14
Dependent Claim
41 words
The method of claim 13, wherein creating the composite
character includes calculating a new weighting factor for each
base glyph in the glyph set from the weighting factors for that
base glyph from the first and second pluralities of weighting
factors.
Claim 15
Independent Claim
192 words
A method of generating a digital font character, comprising: identifying a shape type and a position for each element in
the character; providing a glyph set for each shape type, each glyph set
containing a plurality of different base glyphs; for each element in the character, receiving a first
weighting factor for each base glyph in the glyph set for the
shape type of that element; for each element in the character, receiving a second
weighting factor for each base glyph in the glyph set for the
shape type of that element; for each element in the character, determining a third
weighting factor for each base glyph in the glyph set for the
shape type of that element, the third weighting factor computed
from the first and second weighting factors; for each element in the character, creating a composite
element from the base glyphs in the glyph set for the shape type
of that element, the relative contribution of each base glyph to
the composite element determined by the third weighting factor
determined for that element; and placing the composite elements in the identified positions
to display the master of the character.
Claim 16
Dependent Claim
21 words
The method of claim 15, wherein the third weighting factor
is a weighted average of the first and second weighting factors.
Claim 17
Dependent Claim
16 words
The method of claim 16, wherein the weighted average is
determined by a font design variable.
