Abstract

A computer display system includes a display screen capable of flipping between portrait orientation and landscape orientation and includes a method for repositioning and resizing display windows in response to flipping between such oprientations of the display screen. The windows are moved and resized according to a set of rules to yield displays which take advantage of the new orientation. Where the computer display system includes coordinated, multiple display screens, images controlled for display on fixed-orientation display screens do not change as a result of a flip between orientations of a variable-orientation display screen.

Claims

1. A process, implemented by a computer system including a plurality of display devices, for moving and redimensioning a portion of an image displayed on the plurality of display devices comprising:

assigning a weight to each of a plurality of selected elements of the image portion on a first display device;

individually calculating a plurality of total weights, one for each of the display devices, of the weights of the selected elements located at least in part on each of the display devices;

comparing the total weight corresponding to each display device with the total weight of the first display device to determine whether the image portion is substantially located on the first display device;

identifying a first change in number of displayable pixels along an axis of the first display device; and

moving and redimensioning the image portion displayed on the first display device according to a predefined set of computer-implemented rules responsive to identification of the first change.

2. A computer-implemented process as in claim 1, further comprising:

identifying an image portion not substantially located on a first display device; and

inhibiting the moving and redimensioning of the image portion not substantially located on one of the display devices.

3. A computer-implemented process as in claim 2, wherein the weights comprise:

8 for a top edge of the portion of the image;

4 for a left edge of the portion of the image;

2 for a right edge of the portion of the image; and

1 for a bottom edge of the image portion.
