Abstract

A source document auto-resizing algorithm in a facsimile-capable device. When a user inputs the source document into the facsimile-capable device, the source document is converted into an intermediate converted document with the resizing algorithm resident in the facsimile-capable device. The intermediate converted document is then transmitted to a destination device having predetermined output capabilities, which intermediate converted document is processed into an output document by the destination device in accordance with the predetermined output capabilities.

Claims

1. A method of resizing a source document in a facsimile-capable device, comprising the steps of:

inputting source document data representative of the source document into the facsimile-capable device;

converting the source document data into a converted document with a converting algorithm resident in the facsimile-capable device; and

transmitting the converted document to a destination device having predetermined output capabilities, which the converted document in processed into an output document by the destination device in accordance with the predetermined output capabilities,

wherein the step of converting includes rotating image data of the converted document corresponding to the source document in accordance with the predetermined output capabilities of the destination device, and appending white space to the converted document in accordance with conversion information representative of the predetermined output capabilities of the destination device so that each page of the converted document is converted to a single corresponding page such that the converted document meets the predetermined output capabilities of the destination device.

2. The method of claim 1, wherein the source document data in the step of inputting is provided from a network client via a network.

3. The method of claim 1, wherein the source document data in the step of inputting is provided manually by a user inserting a document into a document receiving apparatus of a controller.

4. The method of claim 1, wherein when the source document data in the step of inputting represents document information in a portrait orientation, the document information is rotated counterclockwise ninety degrees.

5. The method of claim 1, wherein the source document data in the step of inputting represents that the source document has dimensions different from that of the output document.

6. The method of claim 5, wherein the source document is smaller in dimensions than the output document.

7. The method of claim 1, wherein the source document data in the step of inputting is representative of the source document having paper dimensions associated with of one of A5, B5, and Statement, and the corresponding paper dimensions of the output document are associated with one of A4, B4, and Letter.

8. The method of claim 1, wherein the facsimile-capable device includes a conversion algorithm resident therein for generating the converted document in the step of converting.

9. The method of claim 1, wherein the facsimile-capable device includes a conversion algorithm resident therein for processing the source document data to determine if the source document represented thereby is oriented in one of portrait and landscape format.

10. The method of claim 9, wherein the conversion algorithm includes a look-up table of conversion information that is accessed during the step of converting to determine a format for the output document.

11. The method of claim 1, wherein the white space appended in the step of appending matches the size of the output document.

12. The method of claim 1, wherein the converted document in the step of converting is processed in a landscape orientation.

13. The method of claim 1, wherein the converted document is transmitted to the device destination device in the step of transmitting, which destination device is a facsimile-capable device, via one of a circuit-switched network and packet-switched network.

14. The method of claim 1, wherein the converted document in the step of converting is retained in the facsimile-capable device.

15. A facsimile-capable controller, comprising:

input means for receiving into the controller source document data representative of a source document; and

a conversion algorithm resident in the controller for converting the source document data into a converted document by automatically resizing the source document in accordance with conversion information;

transmitting the converted document to a destination device having predetermined output capabilities, which the converted document in processed into an output document by the destination device in accordance with the predetermined output capabilities, and

wherein the conversion algorithm further comprises means adapted for rotating image data of the converted document corresponding to the source document in accordance with the predetermined output capabilities of the destination device, wherein white space is appended to the converted document in accordance with the conversion information representative of predetermined output capabilities of the destination device so that each page of the converted document is converted to a single corresponding page such that the converted document meets the predetermined output capabilities of the destination device.

16. The controller of claim 15, wherein the source document data is provided electronically from a network client via a network.

17. The controller of claim 15, wherein the source document data is provided manually by a user inserting a document into the input means that is a document receiving apparatus of the controller.

18. The controller of claim 15, wherein when the source document data represents that the source document is in a portrait orientation, the source document data is rotated counterclockwise ninety degrees.

19. The controller of claim 15, wherein the source document data represents that the source document has dimensions different from that of the output document.

20. The controller of claim 19, wherein the source document is smaller in dimensions than the output document.

21. The controller of claim 15, wherein the source document data is representative of the source document having paper dimensions associated with of one of A5, B5, and Statement, and the corresponding paper dimensions of the output document are associated with one of A4, B4, and Letter.

22. The controller of claim 15, wherein the conversion algorithm resident therein for processing the source document data determines if the source document represented thereby is oriented in one of portrait and landscape format.

23. The controller of claim 15, wherein the conversion algorithm includes a look-up table of the conversion information that is accessed to determine a format for the output document.

24. The controller of claim 15, wherein the appended white space matches the size of the output document.

25. The controller of claim 15, wherein the converted document is processed in a landscape orientation.

26. The controller of claim 15, wherein the converted document is transmitted to the device destination device, which destination device is a facsimile-capable device, via one of a circuit-switched network and packet-switched network.

27. The controller of claim 15, wherein the converted document is retained in the controller.
