Abstract
Abstract A method of displaying predefined characters contained in a font which maintain their artistically pleasing shapes as font design properties change over a font design axis (which defines a variable font design property) including the steps of: (1) including within each character definition a character-specific transition point which will be used to select a predefined character attribute of the character when it is displayed, the transition point lying along the font design axis; (2) selecting a value for the variable font design property of the character along the font design axis, and then determining a predefined character attribute for the character based upon the location of the selected value in relation to the character-specific transition point along the font design axis; and (3) displaying the character using the selected value of the variable font design property and the determined, predefined character attribute.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
198 words
A method of displaying a character, comprising: obtaining a digital character definition for the character from a font; determining an optional character design feature in the font, the presence or absence of said optional design feature which changes the design of the character but not a specific character that is represented; determining a transition point for a specified variable characteristic of the font as a point where the font has an unpleasing look in one relation with the specified variable characteristic when the optional design feature is included and has an acceptable look in the other relation with the specified variable characteristic when the optional design feature is included; selecting a value for said specified variable characteristic of the font design property; comparing the value of the specified design characteristic to the transition point; and displaying a character with the optional character design feature only if said specified variable characteristic is within the other relation that produces an acceptable look, so that character includes said specified design characteristic if it is within the acceptable characteristic, and the same character does not include the specified design characteristic if it is within said one relation that produces an unpleasing look.
Claim 2
Independent Claim
198 words
A method of displaying a character, comprising: obtaining a digital character definition for the character from a font; determining an optional character design feature in the font, the presence or absence of said optional design feature which changes the design of the character but not a specific character that is represented; determining a transition point for a specified variable characteristic of the font as a point where the font has an unpleasing look in one relation with the specified variable characteristic when the optional design feature is included and has an acceptable look in the other relation with the specified variable characteristic when the optional design feature is included; selecting a value for said specified variable characteristic of the font design property; comparing the value of the specified design characteristic to the transition point; and displaying a character with the optional character design feature only if said specified variable characteristic is within the other relation that produces an acceptable look, so that character includes said specified design characteristic if it is within the acceptable characteristic, and the same character does not include the specified design characteristic if it is within said one relation that produces an unpleasing look.
Claim 3
Dependent Claim
24 words
The method of claim 1 wherein the font design property is selected from the group consisting of character weight, character width and character size.
Claim 4
Dependent Claim
16 words
The method of claim 1 wherein the optional character design feature comprises an opening between serifs.
Claim 5
Dependent Claim
14 words
The method of claim 1 wherein the optional character design feature comprises a stem.
Claim 6
Dependent Claim
40 words
The method of claim 1 wherein the optional character design feature is displayed when the user-selected value of the font design property is below the transition point and is not displayed when the user-selected value is above the transition point.
Claim 7
Dependent Claim
27 words
The method of claim 1 wherein the character definition includes a second transition point that determines whether a second optional character design feature is to be displayed.
Claim 8
Dependent Claim
20 words
The method of claim 6 wherein the first and second optional character design features each comprise an opening between serifs.
Claim 9
Independent Claim
255 words
A method of displaying a character, comprising: obtaining a digital character definition for a specific character from a multimaster font, the definition including, being a value of a first font design property lying on a first font design axis, a second transition point, being a value of a second font design property lying on a second font design axis, and an optional character design feature which is a feature that is can be present in said specific character, or not present in said specific character, and a transition point for a specified variable characteristic of the character as a point where the character has an unpleasing look in one relation with the specified variable characteristic when the optional design feature is included and has an acceptable look in the other relation with the specified variable characteristic when the optional design feature is included; acquiring user-selected values of the first and second font design properties; comparing the user-selected value of the first font design property to the first transition point in the character definition; comparing the user-selected value of the second font design property to the second transition point in the character definition; and displaying the character with the optional character design feature only if the user selected value has a specified relation with said transition point, and otherwise displaying the character without the optional design feature, according to the result of the comparisons between the user-selected values and the transition points, whereby a change in the design of the character occurs at the transition points.
Claim 10
Independent Claim
255 words
A method of displaying a character, comprising: obtaining a digital character definition for a specific character from a multimaster font, the definition including, being a value of a first font design property lying on a first font design axis, a second transition point, being a value of a second font design property lying on a second font design axis, and an optional character design feature which is a feature that is can be present in said specific character, or not present in said specific character, and a transition point for a specified variable characteristic of the character as a point where the character has an unpleasing look in one relation with the specified variable characteristic when the optional design feature is included and has an acceptable look in the other relation with the specified variable characteristic when the optional design feature is included; acquiring user-selected values of the first and second font design properties; comparing the user-selected value of the first font design property to the first transition point in the character definition; comparing the user-selected value of the second font design property to the second transition point in the character definition; and displaying the character with the optional character design feature only if the user selected value has a specified relation with said transition point, and otherwise displaying the character without the optional design feature, according to the result of the comparisons between the user-selected values and the transition points, whereby a change in the design of the character occurs at the transition points.
Claim 11
Dependent Claim
20 words
The method of claim 8 wherein the first and second font design properties comprise character width and character weight, respectively.
Claim 12
Dependent Claim
19 words
The method of claim 8 wherein the optional character design feature comprises an opening between serifs or a stem.
Claim 13
Dependent Claim
12 words
The method of claim 1 wherein the transition point is character specific.
Claim 14
Dependent Claim
26 words
A method as in claim 1 wherein said optional character design feature is a stem on the character, and said character definition is a character boldness.
