Claim 12

The method of claim 9 where the vertical alignment step further comprises: inferring if top and bottom edges of the content object align to framework members, if both edges align to framework members, then moving and resizing the content object so that the positions of the top and bottom edges of the content object are the same as the new locations of the framework members to which both edges align in the redefined page, if only one edge of the content object is aligned to a framework member, then moving the content object vertically so that the position of the edge of the content object is the same as the position of the framework member to which it is aligned without resizing the content object, and if neither edge of the content object aligns to a framework member, then moving the content object vertically so as to keep a center of the content object in the same relative position on the page without resizing the content object.

Claim 13

The method of claim 1 wherein the step of repositioning the content object includes: aligning the content object on the page according to the inferred alignment.

Claim 14

The method of claim 12 where the alignment step comprises: inferring if left and right edges of the content object align to framework members, if both edges align to framework members, then moving and resizing the content object so that the positions of the left and right edges of the content object are the same as the new locations of the framework members to which both edges align in the redefined page, if only one edge of the content object is aligned to a framework member, then moving the content object horizontally so that the position of the edge of the content object is the same as the position of the framework member to which it is aligned without resizing the content object, and if neither edge of the content object aligns to a framework member, then moving the content object horizontally so as to keep a center of the content object in the same relative position on the page without resizing the content object; and inferring if top and bottom edges of the content object align to framework members, if both edges align to framework members, then moving and resizing the content object so that the positions of the top and bottom edges of the content object are the same as the new locations of the framework members to which both edges align in the redefined page, if only one edge of the content object is aligned to a framework member, then moving the content object vertically so that the position of the edge of the content object is the same as the position of the framework member to which it is aligned without resizing the content object, and if neither edge of the content object aligns to a framework member, then moving the content object vertically so as to keep a center of the content object in the same relative position on the page without resizing the content object.

Claim 15

The method of claim 13 where a content object that includes a group or graphics is reositioned with proportional resizing overriding repositioning normally conducted in accordance with the alignment step.

Claim 16

The method of claim 1 where the repositioning is performed by a look-up operation where the inferred alignment is indexed in an alignment table to map an individual pattern of edge alignment with a resultant move and resize operation to be performed on the content object.

Claim 17

The method of claim 1 where a content object that includes a group of graphics is repositioned with proportional resizing overriding repositioning normally conducted in accordance with the repositioning step.

Claim 18

The method of claim 1 wherein a content object that includes a bleed edge is repositioned to maintain its relative fixed distance from an adjacent edge on the document.

Claim 19

A computer program, tangibly stored on a computer-readable medium, for positioning a content object on a page of an electronic document, the page having a page framework having one or more framework members defined on the page, the page having a content object having a position on the page, the position being defined independent of any framework member of the page framework, the program comprising instructions operable for causing a computer to: infer an alignment of a content object to at least one of the framework members, without regard to any previously defined or inferred alignment of the content object to any framework members, based on the position of the content object relative to the positions of the framework members on the page at the time of a user request to change the page framework, the request not establish any relationship linking the content object to any framework member; redefine the page framework according to the user request; and reposition the content object on the page with reference to the redefined page framework according to the inferred alignment.

Claim 20
