Abstract
Abstract A method typesets a set of glyphs. A current glyph is selected from the set of glyphs and a current position of the current glyph is selected. A next position of a next glyph is determined, where the next glyph is selected from the set of glyphs. The determination of the next position of the next glyph first represents the current glyph as a two-dimensional distance field and then determines the next position using the current position, an escapement of the current glyph, and an alignment of the two-dimensional distance field. The current glyph is then updated to be the next glyph and the current position is updated to be the next position. The selection of the next glyph and the determination of the next position continue until a termination condition is satisfied.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
123 words
A computer implemented method for typesetting a set of glyphs represented as a set of graphical objects, comprising: selecting a current glyph from the set of glyphs represented as a set of graphical objects; selecting a current position of the current glyph; and determining a next position of a next glyph, the next glyph selected from the set of glyphs, the selection continuing until a termination condition is satisfied, the determining further comprising: representing the current glyph as a two-dimensional distance field; determining the next position using the current position, an escapement of the current glyph, and an alignment of the two-dimensional distance field; updating the current glyph to be the next glyph; and updating the current position to be the next position.
Claim 2
Dependent Claim
123 words
A computer implemented method for typesetting a set of glyphs represented as a set of graphical objects, comprising: selecting a current glyph from the set of glyphs represented as a set of graphical objects; selecting a current position of the current glyph; and determining a next position of a next glyph, the next glyph selected from the set of glyphs, the selection continuing until a termination condition is satisfied, the determining further comprising: representing the current glyph as a two-dimensional distance field; determining the next position using the current position, an escapement of the current glyph, and an alignment of the two-dimensional distance field; updating the current glyph to be the next glyph; and updating the current position to be the next position.
Claim 3
Dependent Claim
17 words
The method of claim 1 wherein the alignment aligns the two-dimensional distance field to a pixel grid.
Claim 4
Dependent Claim
20 words
The method of claim 1 wherein the alignment aligns the two-dimensional distance field to a component of a pixel grid.
Claim 5
Dependent Claim
16 words
The method of claim 1 wherein the alignment uses a selected iso-contour of the distance field.
Claim 6
Dependent Claim
127 words
A computer implemented method for typesetting a set of glyphs represented as a set of graphical objects, comprising: selecting a current glyph from the set of glyphs represented as a set of graphical objects; selecting a current position of the current glyph; and determining a next position of a next glyph, the next glyph selected from the set of glyphs, the selection continuing until a termination condition is satisfied, the determining further comprising: representing the current glyph as a two-dimensional distance field; selecting an iso-contour of the two-dimensional distance field; determining the next position using the current position, an escapement of the current glyph, and the selected iso-contour; updating the current glyph to be the next glyph; and updating the current position to be the next position.
Claim 7
Dependent Claim
127 words
A computer implemented method for typesetting a set of glyphs represented as a set of graphical objects, comprising: selecting a current glyph from the set of glyphs represented as a set of graphical objects; selecting a current position of the current glyph; and determining a next position of a next glyph, the next glyph selected from the set of glyphs, the selection continuing until a termination condition is satisfied, the determining further comprising: representing the current glyph as a two-dimensional distance field; selecting an iso-contour of the two-dimensional distance field; determining the next position using the current position, an escapement of the current glyph, and the selected iso-contour; updating the current glyph to be the next glyph; and updating the current position to be the next position.
Claim 8
Dependent Claim
21 words
The method of claim 5 wherein the selected iso-contour determines an alignment of the two-dimensional distance field to a pixel grid.
