Abstract

This invention relates to a method, a computer program product, a device and a system for formatting an object to obtain a formatted object, wherein the object comprises a plurality of elements, and wherein the formatted object is affected by at least one constraint, wherein the constraint is scaled by a first scaling factor to obtain a scaled constraint; wherein at least one of the elements is scaled by a second scaling factor to obtain a scaled element; wherein a layout structure is generated for the plurality of elements including the scaled element under consideration of the scaled constraint; and wherein the layout structure is scaled by a third scaling factor to obtain the formatted object.

Claims

1. A method for formatting an object to obtain a formatted object, wherein said object comprises a plurality of elements, and wherein said formatted object is affected by at least one constraint, said method comprising:

scaling said constraint by a first scaling factor to obtain a scaled constraint;

scaling at least one of said elements by a second scaling factor to obtain a scaled element;

generating a layout structure for said plurality of elements including said scaled element under consideration of said scaled constraint; and

scaling said layout structure by a third scaling factor to obtain said formatted object.

2. The method according to claim 1, wherein said first and second scaling factors are larger than one, and wherein said third scaling factor is smaller than one.

3. The method according to claim 1, wherein said first and second scaling factors are substantially equal, and wherein said third scaling factor is substantially a reciprocal value of said first scaling factor.

4. The method according to claim 1, wherein said first scaling factor is a product of a fourth and a fifth scaling factor, and wherein said fourth scaling factor is substantially a reciprocal value of said third scaling factor.

5. The method according to claim 1, wherein said generating of said layout structure comprises:

determining a boundary for said scaled element;

checking if a dimension of said boundary violates a limit defined by said scaled constraint; and

formatting a content of said scaled element to said limit defined by said scaled constraint, if said dimension of said boundary violates said limit defined by said scaled constraint.

6. The method according to claim 1, wherein in said generating of said layout structure, a hyphenation algorithm is applied to a text contained in said at least one element that is scaled by said second scaling factor.

7. The method according to claim 1, wherein said generating of said layout structure is at least partially defined by a style sheet.

8. The method according to claim 1, wherein said object is a document, and wherein said elements of said document are defined by a markup language.

13. A computer program product comprising a computer program with instructions stored on a readable medium, the instructions operable to cause a processor to perform the method steps of claim 1.

14. The computer program product according to claim 13, wherein said computer program is related to a browsing application or to a part thereof.

15. A computer program product comprising a computer program with instructions stored on a readable medium, the instructions operable to cause a processor to perform the method steps of claim 5.

16. A computer program product comprising a computer program with instructions operable to cause a processor to perform the method steps of claim 6.

9. A device for formatting an object to obtain a formatted object, wherein said object comprises a plurality of elements, and wherein said formatted object is affected by at least one constraint, said device comprising:

means arranged for scaling said constraint by a first scaling factor to obtain a scaled constraint;

means arranged for scaling at least one of said elements by a second scaling factor to obtain a scaled element;

means arranged for generating a layout structure for said plurality of elements including said scaled element under consideration of said scaled constraint; and

means arranged for scaling said layout structure by a third scaling factor to obtain said formatted object.

10. The device according to claim 9, wherein said device is a mobile phone or a part thereof.

11. The device according to claim 9, wherein said means arranged for generating said layout structure comprises:

means arranged for determining a boundary for said scaled element;

means arranged for checking if a dimension of said boundary violates a limit defined by said scaled constraint; and

means arranged for formatting a content of said scaled element to said limit defined by said scaled constraint, if said dimension of said boundary violates said limit defined by said scaled constraint.

12. The device according to claim 9, wherein said means arranged for generating said layout structure comprises:

means arranged for applying a hyphenation algorithm to a text contained in said at least one element that is scaled by said second scaling factor.

17. A system for formatting an object to obtain a formatted object, wherein said object comprises a plurality of elements, and wherein said formatted object is affected by at least one constraint, said system comprising:

means arranged for scaling said constraint by a first scaling factor to obtain a scaled constraint;

means arranged for scaling at least one of said elements by a second scaling factor to obtain a scaled element;

means arranged for generating a layout structure for said plurality of elements including said scaled element under consideration of said scaled constraint; and

means arranged for scaling said layout structure by a third scaling factor to obtain said formatted object.

18. The system according to claim 17, wherein said means are jointly implemented by a network element and a mobile phone in a mobile radio communications network.
