Claims Analysis
Total Claims: 22
Claim 1
Independent Claim
48 words
A figure processing method comprising the step of determining whether a plurality of sample points including adjacent sample points are moved together in accordance with a state of the adjacent sample points upon designation of movement of a desired point in the sample points representing a figure pattern.
Claim 2
Dependent Claim
45 words
A figure processing method comprising the steps of: designating movement of a desired point of sample points representing a figure pattern; and determining a movement amount along an x- or y-axis on the basis of the desired point and another point designated on a screen.
Claim 3
Dependent Claim
31 words
A method according to claim 1, wherein the state of the adjacent sample points is determined whether x- or y-coordinates of the plurality of sample points are equal to each other.
Claim 4
Dependent Claim
36 words
A method according to claim 2, wherein the movement amount is an x-axis difference between the desired sample point and said another point or a y-axis difference between the desired sample point and said another point.
Claim 5
Dependent Claim
70 words
A figure processing method comprising the steps of: designating deletion of a desired sample point in a sample point array having an attribute for expressing a figure pattern; and generating a figure pattern corresponding to a present sample point array on the basis of an attribute of at least one sample point adjacent to the desired sample point subjected to deletion in response to the step of designating the deletion.
Claim 6
Dependent Claim
25 words
A method according to claim 5, wherein the attribute includes information representing that the sample point represents a point of a straight or curve portion.
Claim 7
Dependent Claim
62 words
A figure processing method comprising the steps of: designating a desired area subjected to deletion and included in the sample point array having an attribute for expressing a figure pattern; and generating a figure pattern between end portions in accordance with an attribute of a sample point of an end portion in the area after the step of designating the desired area.
Claim 8
Dependent Claim
25 words
A method according to claim 7, wherein the attribute includes information representing that the sample point represents a point of a straight or curve portion.
Claim 9
Dependent Claim
60 words
A figure processing method comprising the steps of: designating insertion of a sample point in a sample point array having an attribute representing a figure pattern; and determining an attribute of the inserted point on the basis of an attribute of a sample point adjacent to the inserted point after the step of designating the insertion of the sample point.
Claim 10
Dependent Claim
36 words
A method according to claim 9, wherein the step of designating insertion comprises the step of designating two adjacent points of the sample point array and inserting a sample point between the two designated adjacent points.
Claim 11
Dependent Claim
19 words
A method according to claim 9, wherein the step of determining the attribute comprises interruption for another figure process.
Claim 12
Dependent Claim
45 words
A figure processing method comprising the steps of: determining style information; appropriately determining a straight line portion and a curve portion from a coordinate point array representing an outline extracted from pattern data, on the basis of the set style information; and generating font data.
Claim 13
Dependent Claim
81 words
A figure processing method comprising the steps of: designating to locate one point or each of a plurality of points representing a figure pattern at a position of a desired point while a pattern representing an x- or y-coordinate of the desired point is kept displayed, thereby locating an x- or y-coordinate of said one point or said each of the plurality of points is set at the x- or y-coordinate of the desired point; and generating a corresponding figure pattern.
Claim 14
Dependent Claim
44 words
A method according to claim 13, wherein the step of designating to locate said one point or said each of the plurality of points includes the step of designating an area including one target point or an area including a plurality of target points.
Claim 15
Dependent Claim
61 words
A figure processing method comprising the steps of: designating to change an attribute of a desired sample point of a sample point array having an attribute for expressing a figure pattern; changing the attribute of the sample point in accordance with the step of designating to change the attribute; and generating a figure pattern on the basis of the changed attribute.
Claim 16
Dependent Claim
25 words
A method according to claim 15, wherein the attribute includes information representing that the sample point is a point of a straight or curve portion.
Claim 17
Dependent Claim
63 words
A figure processing method comprising the step of switching between a mode for connecting adjacent pieces of sample point information by a straight line to express a figure pattern and a mode for expressing the figure pattern by a straight line or curve when the figure pattern is to be visually output on the basis of sample point information representing the figure pattern.
Claim 18
Dependent Claim
20 words
A method according to claim 17, wherein the step of switching comprises an interruption process for another figure process method.
Claim 19
Dependent Claim
47 words
A figure processing method comprising the steps of designating a point on a first curve and a point on a second curve, the first and second curves constituting a figure pattern; generating an imaginary line associated with the first and second curves; and changing the imaginary line.
Claim 20
Dependent Claim
52 words
A figure processing method comprising the switching step of, when a figure pattern is visually output and edited by editing sample points, switching between a mode for displaying the sample point and a mode for not displaying the sample point on the basis of the sample point information representing the figure pattern.
Claim 21
Dependent Claim
19 words
A method according to claim 20, wherein the switching step comprises an interruption process for another figure processing method.
Claim 22
Dependent Claim
58 words
A figure processing method comprising the step of, when a figure pattern is visually output and edited by editing sample points, setting sample point information to be displayable on the basis of the sample point information representing the figure pattern, the sample point information being switched to values of a plurality of coordinate systems in accordance with designation.
