Abstract

A system for manipulating page-breaks in an electronic document. A User Interface Process provides a graphical user interface allowing a user to select a page-break within an electronic document and then identify a new location for the page-break. A System Process performs the steps of moving the selected page-break to the new location and adjusting the scaling and the automatic page-breaks for the remainder of the document to accommodate the page-break at the new location.

Claims

1. In a computer system having a graphical user interface including a display device and an input device, the input device having a positioning means for controlling movement of a display-element on the display device and a signal generating means for providing an input signal, a method of manipulating the position of vertically and horizontally oriented page-breaks in an electronic document having multiple pages and displayed on the display device, the method comprising the steps of:

in response to actuating the positioning means of the input device, positioning the display-element over a page-break, the page-break being located at an initial location in the electronic document;

in response to actuating the signal generating means of the input device while the display-element is over the page-break,

displaying a phantom page-break positioned over the page-break, and

activating a drag mode;

in response to actuating the positioning means of the input device while the phantom page-break is displayed and the drag mode is active, positioning the phantom page-break at a new location in the electronic document; and

in response to actuating the signal generating means of the input device while the drag mode is activated and the phantom page-break is positioned over a new location;

deactivating the drag mode,

moving the page-break to the new location, and

removing the phantom page-break.

2. The method of claim 1, wherein each page of the electronic document has a calculated scaling factor, the scaling factor identifies an amount to scale the contents of the page in order for the contents to fit within a set of predefined dimensions, and in response to moving the page-break to a new location, further comprises the steps of:

determining a new scaling factor for the page immediately before the page-break;

determining a minimum scaling factor for the document; and

repaginating the document in accordance with the minimum scaling factor.

3. The method of claim 1, wherein each page-break of the electronic document can be one of a plurality of types including a manual type page-break and an automatic type page-break, and in response to moving the page-break to the new location, further comprises the steps of:

if the page-break is an automatic type page-break, converting the page-break to a manual type page-break;

if the page-break is a vertical page-break and an adjacent page-break to the immediate left of the page-break is an automatic type page-break, in response to moving the page-break to the right of the initial location, converting the adjacent page-break to the immediate left of the page-break to a manual type page-break; and

if the page-break is a horizontal page-break and an adjacent page-break immediately above the page-break is an automatic type page-break, in response to moving the page-break below the initial location, converting the adjacent page-break immediately above the page-break to a manual type page-break.

4. The method of claim 3, wherein the page-break is a vertical page-break and each page of the electronic document has an associated scaling factor, each scaling factor identifying an amount to scale the contents of the associated page in order for the contents of the associated page to fit within a set of predefined dimensions, further comprising the steps of:

if a first bordering page to the immediate left of the page-break at the new location is bounded by manual type vertical page-breaks, determining a new scaling factor for the first bordering page;

if a second bordering page to the immediate right of the page-break at the new location is bounded by manual type vertical page-breaks, determining a new scaling factor for the second bordering page;

determining a minimum scaling factor of each of the scaling factors for the document; and

repaginating the document in accordance with the minimum scaling factor.

5. A computer-readable medium having computer-executable instructions for performing the steps recited in claim 4.

6. The method of claim 3, wherein the page-break is a horizontal page-break and each page of the electronic document has an associated scaling factor, each scaling factor identifying an amount to scale the contents of the associated page in order for the contents of the associated page to fit within a set of predefined dimensions, further comprising the steps of:

if a first bordering page immediately above the page-break at the new location is bounded by manual type horizontal page-breaks, determining a new scaling factor for the first bordering page;

determining a minimum scaling factor for the document; and

repaginating the document in accordance with the minimum scaling factor.

7. A computer-readable medium having computer-executable instructions for performing the steps recited in claim 6.

8. A computer system for manipulating the position of vertically and horizontally oriented page-breaks in an electronic document, comprising:

a processing unit;

a memory storage device;

an input device coupled to the processing unit for sending commands to the processing unit;

a pixel-based display device coupled to the processing unit for displaying data;

a program module, stored in the memory storage device, for providing instructions to the processing unit;

the processing unit, responsive to the instructions of the program module, operative to;

display on the display device, an electronic document having a plurality of pages separated by vertically and horizontally oriented page-breaks, each page having a scaling factor;

in response to receiving a first command from the input device, select a page-break;

in response to selecting a page-break, activate a drag mode for the page-break;

in response to receiving a second command from the input device, drag the page-break to a new location;

in response to receiving a third command, deactivate the drag mode for the page-break;

determine a new scaling factor for each page bordering the page-break;

determine a minimum scaling factor for the document; and

repaginate the document in accordance with the minimum scaling factor.

9. A method for manipulating a selected page-break within an electronic document having multiple pages, wherein the selected page-break can be one of a plurality of types including a manual type page-break and an automatic type page-break, comprising the steps of:

receiving a command to move the selected page-break from an initial location to a new location;

converting the selected page-break to a manual type page-break if the selected page-break is an automatic type page-break;

moving the selected page-break to the new location; and

repaginating the electronic document to accommodate the selected page-break at the new location.

10. The method of claim 9, wherein each page of the electronic document has a scaling factor, the scaling factor identifying an amount to scale the contents of the page in order for the contents of the page to fit within a set of predefined dimensions, and the moving step comprises the steps of:

if the selected page-break is vertically oriented, the new location is to the right of the initial location, and a first adjacent page-break to the immediate left of the selected page-break is an automatic type page-break,

converting the first adjacent page-break to a manual type page-break, and

adjusting the scaling factor for the page to the left of the selected page-break;

if the selected page-break is horizontally oriented, the new location is below the initial location, and a second adjacent page-break immediately above the selected page-break is an automatic type page-break,

converting the second adjacent page-break to a manual type page-break,

adjusting the scaling factor for the page above the selected page-break; and

determining the minimum scaling factor for the electronic document.

11. The method of claim 10, wherein the repaginating step comprises the steps of:

removing all automatic type page-breaks from the electronic document; and

without modifying the location of any manual page-breaks, inserting automatic page-breaks in accordance with the minimum scaling factor for the electronic document ensuring that the contents of each page will fit within the set of predefined dimensions.
