  • Patent number: 8127221
    Abstract: Architecture of one or more algorithms for autofitting objects with non-trivial geometries in documents. The algorithms autofit rectangular objects (such as floaters), when the objects contain both left and right aligned objects, autofit tables, determine correct sizes of a parent object and its child object when the width of the parent object is unknown (referred to as an auto-width), and the width of the parent's child object is expressed in percentages of the parent object width. A two-pass algorithm determines the best (or optimal) sizes of margins, borders, and paddings of objects where any combination thereof can have fixed width, auto width, and/or percentage-expressed width. Additionally, the algorithms can recursively calculate the optimal widths of objects inside other objects, where the outer object width is undefined. The algorithms can process an unlimited number of nesting levels.

  • Patent number: 7979792
    Abstract: A computer-implemented method and computer-readable medium are provided for providing page and table layout services. According to the method, a layout manager program provides layout services to client application programs. The layout manager receives requests from client application programs to format document content. In response to such requests, the layout manager performs one or more callback operations to the client application to retrieve portions of the document to be laid out. Once the portions of the page to be laid out have been retrieved through the callback operations, the layout manager lays out the portions of the document and notifies the client application that the layout is completed. The client application can then query the layout manager for the formatting result.

  • Patent number: 7870500
    Abstract: An approach for positioning a floating object in a workspace of an electronic document is disclosed herein. To accomplish this, the workspace is divided into a plurality of available portions in which floating objects may be positioned. For example, these available portions represent geometrical areas within the workspace that do not include obstacles, such as absolutely positioned objects and other floating objects. The available portions are then evaluated against a plurality of undesirable positioning characteristics in order to determine an optimal position for the floating object within the workspace. The optimal position is then determined to be either a location in the workspace that does not result in any of the undesirable characteristics or, alternatively, a location having the most tolerable of the potentially resultant undesired characteristics.

  • Patent number: 7770111
    Abstract: A method and computer-readable medium are provided for optimized paragraph layout. According to the method, a line-by-line paragraph layout is generated determine a maximum penalty for a paragraph. One or more layout nodes may be generated that include data representing a possible layout of the paragraph to a point within a backing store and identifying any changes to a geometry of the page caused by the layout of the paragraph defined by the layout node. A penalty is also calculated for each of the layout nodes. Each layout node that has a penalty less than the maximum penalty calculated during the line-by-line formatting processing is added to the node pool. This process repeats until only a single layout node remains in the node pool that represents the entire paragraph of text.

  • Patent number: 7698637
    Abstract: A method and computer-readable medium are provided for laying out footnotes. Each footnote includes a footnote reference and corresponding footnote text. According to the method, an attempt is first made to lay out one or more footnotes such that each of the references and the corresponding text all fit completely within one page. If such a layout cannot be made, an attempt is may to lay out each of the footnotes such that all of the reference marks fit on the page and all but one of the corresponding note text fits completely on the page. If such a layout cannot be made, an emergency layout may be generated.

  • Patent number: 7576749
    Abstract: An approach for positioning screen elements on a display screen is disclosed herein. The screen elements represent expressions in a formula and may include one or more glyphs. Optimal positions are determined for the screen elements based on analyzing positional characteristics associated with displaying the screen elements at the resolution supported by the display screen against positional characteristics based on an optimal resolution. This analysis indicates whether the degree of displacement between display of a screen element at the actual resolution and display of the screen element at the optimal resolution would exceed a predetermined threshold level. If not, the screen element is output for display on the display screen based on the positional characteristics associated with the display screen resolution. Otherwise, the positional characteristics based on the actual resolution are modified such that the degree of displacement conforms to the threshold level.

  • Patent number: 7492366
    Abstract: A method and system for optimizing the horizontal spacing of superscripts and subscripts in open type font designs is disclosed. The system includes a module for vertically aligning and spacing characters and a module for horizontally aligning characters having differing baselines in accordance with cut-in information stored in font tables corresponding to each individual character in the font. This additional horizontal spacing adjustment capability provides for optimum placement of character glyphs having differing baselines, e.g., superscript or subscript. The method includes placing a first/next character on a baseline, retrieving a next adjacent character, determining whether a cut-in associated with one or both of the characters can be applied between the two characters, and then applying the appropriate cut-in. Ascertaining whether a cut-in may apply may be accomplished by evaluating relative positions of adjacent glyph bounding boxes.

  • Patent number: 7472340
    Abstract: A computer-implemented method and computer-readable medium are provided for generating a multiple column layout. According to the method, a layout is defined that includes two or more columns and one or more spans that extend across two or more of the columns. Each span is defined as being either content defined or height defined. Content is laid out from a document in each span that is height defined until a defined height is reached. Content is laid out from the document in each span that is content defined until a specified point in the content is reached. When all content or height defined spans have been laid out, the remaining portion of the content is laid out across all of the columns.
