Abstract: The present invention aims at automatically selecting an object which should be displayed in a simplified form in a manner such that user friendliness is not reduced and the drawing time is shortened.

Abstract: An information processing apparatus 10 according to the present invention includes: a registration section 64 for registering plural classes defining respective styles; a search section 52 for searching for, from the registered classes, candidate classes similar to a data set including property values specifying one or more given style characteristics; a presentation section 58 for selectably presenting the retrieved candidate classes; and an application section for giving the one or more input property values as the data set and applying style definition to the structured document using a class confirmed from the selectable candidate classes.

Abstract: Tag selection in web page authoring is facilitated without losing the advantages of WYSIWYG editing. A reference point for object selection is set in response to a user action performed on an editing screen. A reference area enclosing the reference point is set and a view object closest to center of the reference is selected as a reference view object. One or more view objects related to the reference view object are selected. A first rectangle representing the reference view object and a second rectangle representing the related view object are drawn with a space between the two triangles that facilitates object selection. The drawing of the first and second rectangles is independent of the reference view object and the related view object.

Abstract: A control method for controlling display on a display apparatus displaying a plurality of windows in an overlapping manner comprises detecting that contents to be displayed on at least one of the plurality of windows are updated, and displaying an update notification including information identifying a window having the updated display contents on an update notification window provided common to the plurality of windows, in response to the detection of an update of the display contents.

Abstract: The present invention improves application of a style to a view object when a document for a Web page to be edited is edited on a browser-type edit screen. First, a view object is detected from a managed document. Then, a direct style directly described in the managed document and an indirect style identified only by referring to an external document are collected. A browser-type edit screen is generated in which the direct and indirect styles are applied to each view object. The content of the managed document is synchronized with the edited content on the browser-type edit screen based on the editing operations on the browser-type edit screen.

Abstract: The present invention provides a Web page edit screen that allows an author to edit parent and child documents collectively while showing, in an appropriate manner, the content of the child document embedded in the parent document. Associated documents of a Web page to be edited are managed as managed documents individually. Document-by-document structure information is derived from the content of each managed document. Web page structure information is then assembled by connecting the document-by-document structure information based on embed-related code. Edit screen data is generated based on the content of the managed documents and the Web page structure information to generate a browser-type edit screen. The content of a relevant managed document is synchronized with the edited content on the edit screen. The edit screen data is matched with the edited content on the edit screen.

Abstract: The present invention provides a method for automatically determining trackers along a contour of a particular object in a displayed image and a storage medium storing a program for implementing the method. This method comprises the steps of: establishing an initial region containing the particular object therein and setting a plurality of initial points on a boundary of the initial region; setting a target point for scanning the image from each of the plurality of initial points toward an inside of the initial region; selecting one or more tracker candidate points along a line segment between each of the plurality of initial points and the target point, in accordance with magnitude of the contour; and determining a set of tracker candidate points which minimizes a cost, by using dynamic programming, starting from a selected initial point among the plurality of initial points.

Abstract: The present invention allows the positional relationship among a plurality of image layers constituting a composed image to be precisely recognized. More specifically, the present invention is directed to an image composition processing apparatus which generates a composed image which is a superposition of a plurality of image layers and displays it within a window of the screen. When the user designates one of the image layers and moves the pointer into the displayed composed image, the image composition processing apparatus converts only a predetermined area of the image layers above the designated image layer, for example, the area which is superposed in the range of a radius of m picture elements centering the coordinate of the pointer in the composed image, to a translucent state.
