Abstract

An information processing apparatus and method for embedding font information in an electronic document. The apparatus and method comprise generating an electronic document containing editing instructions, and based on the editing instructions, querying to determine whether font information is to be embedded in the electronic document.

Claims

1. An information processing apparatus capable of embedding font information in an electronic document, the information processing apparatus comprising:

a generator that generates an electronic document containing editing instructions; and

a controller that, based on the editing instructions, causes querying to determine whether font information is to be embedded in the electronic document.

2. The information processing apparatus according to claim 1, wherein the editing instructions are reflected in characters, graphic forms, or both, in the electronic document.

3. The information processing apparatus according to claim 2, further comprising a first determiner that determines whether the editing instructions are reflected in the characters,

wherein, when the first determiner determines that the editing instructions are reflected in the characters, the controller causes the querying, and when the first determiner determines that the editing instructions are not reflected in the characters, the controller does not cause the querying.

4. The information processing apparatus according to claim 1, wherein:

the controller displays a screen for specifying additional fonts; and

the information processing apparatus further comprises an embedder that embeds, in the electronic document, font information based on the specified font.

5. The information processing apparatus according to claim 3, further comprising a listing processor for listing fonts,

wherein, the first determiner determines whether font information of the characters reflecting the editing instructions is included in a subset font of the electronic document,

wherein, when the first determiner determines that the font information is included, the listing processor lists fonts corresponding to the characters reflecting the editing instructions, and

wherein, the controller, based on the listed fonts, displays an additional-font directing screen.

6. The information processing apparatus according to claim 3, wherein the first determiner determines whether the font information corresponding to the characters reflecting the editing instructions is included in a subset font already recorded in the electronic document.

7. The information processing apparatus according to claim 1, further comprising a second determiner that determines whether storing of the electronic document or termination of the editing has been directed,

wherein, when the second determiner determines that storing of the electronic document or termination of the editing has not been directed, the controller causes the querying.

8. The information processing apparatus according to claim 1, further comprising a third determiner that detects unembedment of a font corresponding to a character reflecting no editing instruction,

wherein, when the third determiner detects the unembedment of the font, the controller causes querying capable of directing embedment of font information of the unembedded font.

9. The information processing apparatus according to claim 1, wherein the controller displays a font embedded for part of the characters so as be identifiable.

10. The information processing apparatus according to claim 1, further comprising:

a fourth determiner that determines unnecessary font information in response to the generation of the electronic document containing the editing instructions; and

a deleter that deletes, from the electronic document, the unnecessary font information.

11. The information processing apparatus according to claim 1, wherein the querying whether the font information is to be embedded is a representation capable of directing embedding of new font information.

12. The information processing apparatus according to claim 1, wherein the editing instructions include character addition or change of a font corresponding to a character.

13. An information processing method capable of embedding font information in an electronic document, the information processing method comprising:

a generating step that generates an electronic document containing editing instructions; and

a control step that, based on editing instructions, causes querying to determine whether font information is to be embedded in the electronic document.

14. The information processing method according to claim 13, wherein the editing instructions are reflected in characters, graphic forms, or both, in the electronic document.

15. The information processing method according to claim 14, further comprising a first determining step that determines whether the editing instructions are reflected in the characters,

wherein, when the first determining step determines that the editing instructions are reflected in the characters, the control step causes the querying, and when the first determining step determines that the editing instructions are not reflected in the characters, the control step does not cause the querying.

16. The information processing method according to claim 13, wherein:

the control step includes a step that displays a screen for specifying additional fonts; and

the information processing method further comprises an embedding step that embeds, in the electronic document, font information based on the specified font.

17. The information processing method according to claim 14, further comprising a listing step that lists fonts,

wherein, the first determining step determines whether font information of the characters reflecting the editing instructions is included in a subset font of the electronic document, and

wherein, when the first determiner determines that the font information is included, the listing step lists fonts corresponding to the characters reflecting the editing instructions, and

wherein, based on the listed fonts, the control step displays specifying an additional-font directing screen.

18. The information processing method according to claim 14, wherein the first determining step determines whether the font information corresponding to the characters reflecting the editing instructions is included in a subset font already recorded in the electronic document.

19. The information processing method according to claim 13, further comprising a second determining step that determines whether or not storing of the electronic document or termination of the editing has been directed,

wherein, when the second determining step determines that storing of the electronic document or termination of the editing has not been directed, the controller causes the querying.

20. The information processing method according to claim 13, further comprising a third determining step that determines unembedment of a font corresponding to a character reflecting no editing instruction,

wherein, when the third determining step determines that the unembedment of the font, the control step causes querying capable of directing embedment of font information of the unembedded font.

21. The information processing method according to claim 13, wherein the controlling step displays a font embedded for part of the characters so as be identifiable.

22. The information processing method according to claim 13, further comprising:

a fourth determining step that determines unnecessary font information in response to the generation of the electronic document containing the editing instructions; and

a deleting step that deletes, from the electronic document, the unnecessary font information.

23. The information processing method according to claim 13, wherein the querying whether the font information is to be embedded is a representation capable of directing embedment of new font information.

24. The information processing method according to claim 13, wherein the editing instructions include character addition or change of a font corresponding to a character.

25. Computer-executable process steps for causing a computer to execute the method of claim 13.

26. A computer-readable storage medium storing the computer-executable process steps of claim 25.
