Abstract

A computer-implemented method for aligning objects includes receiving a current cursor position, receiving task information and receiving a set of alignments each having an associated priority. The method also includes screening the set of alignments based on task information and a predetermined set of priority factors, determining a highest priority alignment, and outputting a new cursor position corresponding to the highest priority alignment if such an alignment exists.

Claims

1. A computer-implemented method for aligning objects, the method comprising:

receiving a current cursor position;

receiving task information;

receiving a set of alignments each having an associated priority;

screening the set of alignments based on the task information and a predetermined set of priority factors;

determining a highest priority alignment; and

outputting a new cursor position corresponding to the highest priority alignment if such an alignment exists.

2. The method of claim 1, wherein the set of alignments includes at least one of the following:

boundary alignments, required alignments, custom tool alignments, construction lines, grid lines, page boundaries and graphical objects.

3. The method of claim 1, further comprising:

determining a minimum priority; and

eliminating alignments having a priority less than the minimum priority during the screening of the set of alignments.

4. The method of claim 1, wherein the outputting of a new cursor position includes an annotation describing the highest priority alignment.

5. A system for aligning an object, the system comprising:

a computer system for executing computer code to produce and displaying an electronic document having a an object therein;

a display device for displaying the electronic document; and

a computer readable storage medium for storing the computer code, the computer code including

computer instructions for receiving a current cursor position;

computer instructions for receiving task information;

computer instructions for receiving a set of alignments each having an associated priority;

computer instructions for screening the set of alignments based on the task information and a predetermined set of priority factors;

computer instructions for determining a highest priority alignment; and

computer instructions for outputting a new cursor position corresponding to the highest priority alignment if such an alignment exists.

6. The system of claim 5, wherein the set of alignments includes at least one of the following:

boundary alignments, required alignments, custom tool alignments, construction lines, grid lines, page boundaries and graphical objects.

7. The system of claim 5, further comprising:

computer instructions for determining a minimum priority; and

computer instruction for eliminating alignments having a priority less than the minimum priority during the screening of the set of alignments.

8. The system of claim 5, wherein the computer instructions for outputting a new cursor position includes computer instructions for outputting an annotation describing the highest priority alignment.

9. A computer readable medium containing program instructions for aligning an object, the computer readable medium comprising:

computer readable code devices for receiving a current cursor position;

computer readable code devices for receiving task information;

computer readable code devices for receiving a set of alignments each having an associated priority;

computer readable code devices for screening the set of alignments based on the task information and a predetermined set of priority factors;

computer readable code devices for determining a highest priority alignment; and

computer readable code devices for outputting a new cursor position corresponding to the highest priority alignment if such an alignment exists.

10. The computer readable medium of claim 9, wherein the set of alignments includes at least one of the following:

boundary alignments, required alignments, custom tool alignments, construction lines, grid lines, page boundaries and graphical objects.

11. The computer readable medium of claim 9, further comprising:

computer readable code devices for determining a minimum priority; and

computer readable code devices for eliminating alignments having a priority less than the minimum priority during the screening of the set of alignments.

12. The computer readable medium of claim 9, wherein the computer readable code devices for outputting a new cursor position includes computer readable code devices for outputting an annotation describing the highest priority alignment.
