Abstract

According to one embodiment of the present invention, a method for inserting a PDF shared resource back into a PDF statement is provided. The method includes storing a set of statements, wherein each statement has been extracted from a document and each statement contains indirect objects. A set of resources is then stored, wherein the resources have been extracted from the document, and the resources include a set of indirect objects. All of the indirect objects in a selected one of the stored statements are then enumerated and a determination is made of which of the indirect objects contain keys. A key value for the enumerated indirect objects containing keys is then read, and the indirect objects in the stored set of resources associated with each key are identified. Stream data is then copied from the indirect objects in the stored set of resources into the selected ones of the stored statements.

Claims

1. A method comprising:

storing a set of statements, wherein each statement has been extracted from a document and each statement contains indirect objects;

storing a set of resources, wherein said resources have been extracted from said document, said resources including a set of indirect objects;

enumerating all of said indirect objects in a selected one of said stored statements;

determining which of said indirect objects contains keys;

reading a key value for said enumerated indirect objects containing keys;

identifying indirect objects in said stored set of resources associated with each key; and

copying stream data from said indirect objects in said stored set of resources into said selected one of said stored statements.

2. The method according to claim 1 wherein said documents, statements, and resources are PDF documents, PDF statements and PDF shared resources, respectively.

3. A method according to claim 2 wherein said PDF document is a PDF report and said set of PDF statements are included in said PDF report.

4. A method according to claim 2 wherein said key is an identifier of an indirect object used by a stored PDF statement.

5. A method according to claim 4 wherein said stored PDF resources include a list of indirect objects each identified by a key number.

6. A method according to claim 1 wherein said step of reading further comprises reading a key value from a resource object dictionary.

7. A method according to claim 2 wherein said PDF statement is a bank statement.

8. A method comprising:

receiving a request for a stored PDF statement, said stored PDF statement having been stored along with a set of PDF shared resources, wherein said PDF shared resources and said PDF statement have been extracted from a PDF document, said stored PDF statement and said stored PDF shared resources including indirect objects;

enumerating all of said indirect objects in said requested stored PDF statement;

reading a key value for selected ones of said enumerated indirect objects containing a key;

identifying indirect objects in said stored set of PDF resources associated with each key;

copying stream data from said indirect objects in said stored set of PDF resources into said requested stored PDF statements; and

outputting said requested PDF statement including indirect objects with said stream data.

9. A method according to claim 8 wherein said selected ones of said enumerated indirect objects containing a key are those indirect objects associated with a resource needed by said requested stored PDF statement.

10. A method according to claim 8 further comprising printing said outputted PDF statement using said indirect objects with said copied stream data.

11. A method according to claim 8 wherein said PDF statement is a credit card statement.

12. A method according to claim 8 wherein said PDF document is a PDF report.

13. A system comprising:

an object repository containing a set of stored PDF statements extracted from a PDF report and a set of PDF shared resource objects extracted from said PDF report; and

a statement reassembly unit for reassembling PDF statements with a set of corresponding PDF resources, said corresponding PDF resources being generated using selected ones of said stored PDF shared resource objects.

14. A system according to claim 13 further comprising a statement extraction unit for extracting said set of stored PDF statements and said PDF shared resource objects from said PDF report.

15. A system according to claim 13 wherein said reassembled PDF statement includes a set of indirect objects defining PDF resources.

16. A system according to claim 15 wherein said reassembled PDF statement includes a key and a set of stream data.

17. A system according to claim 16 wherein said reassembly unit transfers stream data from said stored PDF shared resource objects to said reassembled PDF statement.

18. A system according to claim 17 wherein said stored PDF statements include a set of indirect objects, some of said indirect objects having a key.

19. A system according to claim 18 wherein said reassembly unit determines a key of an indirect object in said stored PDF statement, and transfers data from an indirect object in said stored PDF shared resource object having a corresponding key to said indirect object in said stored PDF statement.

20. A computer program product for inserting a shared resource back into a stored statement, said computer program product comprising:

a computer usable medium having computer usable program code embodied therewith, said computer usable program code comprising;

computer usable program code configured to;

store a set of statements wherein each said statement has been extracted from a document and each statement contains indirect objects;

store a set of resources, resources have been extracted from said document, said resources including a set of indirect objects;

enumerate all of said indirect objects in a selected one of said stored statements;

determine which of said indirect objects contain keys;

read a key value for said enumerated indirect objects containing keys;

identify indirect objects in said stored set of resources associated with each key; and

copy stream data from said indirect objects in said stored set of resources into said selected one of said stored statements.

21. A computer program product according to claim 20 wherein said documents, statements, and resources are PDF documents, PDF statements and PDF shared resources, respectively.

22. A computer program product according to claim 21 wherein said PDF document is a PDF report and said set of PDF statements are included in said PDF report.

23. A computer program product according to claim 22 wherein said key is an identifier of an indirect object used by a stored PDF statement.

24. A computer program product according to claim 23 wherein said stored PDF resources include a list of indirect objects each identified by a key number.

25. A computer program product according to claim 20 wherein said computer usable program code is further configured to read a key value from a resource object dictionary.
