Claim 12

Independent Claim 76 words

A system for generating images of characters, comprising: a font subsystem which is responsive to identification of characters to access at least one font file to retrieve glyphs associated with the identified characters, and data tables that contain information about glyphs in the font; and a font table synthesizer which is responsive to the absence of a predetermined data table for creating and storing said table on the basis of data contained in the font file.

Claim 13

Independent Claim 76 words

A system for generating images of characters, comprising: a font subsystem which is responsive to identification of characters to access at least one font file to retrieve glyphs associated with the identified characters, and data tables that contain information about glyphs in the font; and a font table synthesizer which is responsive to the absence of a predetermined data table for creating and storing said table on the basis of data contained in the font file.

Claim 14

Dependent Claim 44 words

The system of claim 11 wherein said font subsystem determines whether a predetermined data table is contained in the font file, and causes said synthesizer to create said table when a determination is made that the table is not present in the font file.

Claim 15

Dependent Claim 26 words

The system of claim 11 wherein said font synthesizer stores said table in an annex file that is associated with, but separate from, the font file.

Claim 16

Dependent Claim 54 words

The system of claim 13 wherein said font subsystem determines whether a predetermined data table is contained in either the font file or the annex file, and causes said synthesizer to create said table when a determination is made that the table is not present in either the font file or the annex file.

Claim 17

Dependent Claim 67 words

The system of claim 12 wherein said font subsystem operates in a first mode to cause said synthesizer to automatically create the table in response to said determination, and in a second mode to provide an indication when a data table is determined not to be present and thereafter cause said synthesizer to create the table in response to a request that is responsive to said indication.

Claim 18

Independent Claim 65 words

A method for providing data that relates to the implementation of a font, comprising the steps of: receiving a request for a data table that pertains to the implementation of a font; determining whether the data table is present in a file containing the font; and synthesizing said table from data contained in said file if the table is not present in the font file.

Claim 19

Independent Claim 65 words

A method for providing data that relates to the implementation of a font, comprising the steps of: receiving a request for a data table that pertains to the implementation of a font; determining whether the data table is present in a file containing the font; and synthesizing said table from data contained in said file if the table is not present in the font file.

Claim 20

Dependent Claim 23 words

The method of claim 16 further including the step of storing the synthesized table in an annex file separate from said font file.

Claim 21

Dependent Claim 92 words

The method of claim 16 further including the steps of determining whether said data table is of a first type or a second type when the data table is determined not to be present in the font file; automatically initiating said synthesizing step if said data table is of said first type; or, providing an indication that said data table is not present in the font file if said data table is of said second type, and initiating said synthesizing step upon receipt of a request that is responsive to said indication.

Claim 22

Dependent Claim 48 words

The method of claim 16 wherein the step of synthesizing said data table comprises the steps of: building a font map that contains information about individual glyphs in the font; determining relationships between items of information in the font map; and constructing a table which identifies said relationships.

Claim 23

Dependent Claim 27 words

The method of claim 19 wherein some of the information in said font map is specific to the font, and other information is generic to multiple fonts.

Claim 24
