摘要： Methods and apparatus implementing systems and techniques for traversing a hierarchical layout template to accelerate a constraint-driven backtracking search for a solution of the layout template. In general, in one implementation, the techniques include identifying a shared content element constraint that defines a content requirement common to all layout structures possible in a choice substructure in a hierarchical layout template, and associating the shared content element constraint with a root node of the choice substructure in the hierarchical layout template. In another aspect, the techniques include receiving content elements to be presented according to a hierarchical layout template that includes a choice substructure including a root node having a shared content element constraint that defines a content requirement common to all layout structures possible in the choice substructure, and traversing the hierarchical layout template to generate a layout structure that accommodates the content elements, said traversing including traversing the hierarchical layout template based at least in part on the shared content element constraint associated with the root node.

摘要： A method and apparatus for identifying words stored in a portable electronic document. A digital computation apparatus stores a page of a document including characters in text segments that have not been identified as words. A word identifying mechanism analyzes the text segments of the page and stores the text segments as text objects in a linked list. The word identifying mechanism identifies words from the text objects in the linked list by analyzing the text objects for word breaks and by analyzing gaps between text objects using position data associated with the text segments. The identified words are stored in a word list and are sorted if necessary. A method of the present invention receives a text segment from a page of a document having multiple text segments and associated position data, including x and y coordinates for each text segment. A text object is created for each text segment, and the text objects are entered into a linked list. Words are then identified from the linked list by analyzing the text objects for word breaks and by analyzing gaps between text objects using the associated position data. Words that are identified in the text objects are added to a word list. The above steps are repeated until the end of the page is reached. The method and apparatus can be used for searching for words in a portable electronic document.
摘要翻译：一种用于识别存储在便携式电子文档中的字的方法和装置。一种数字计算装置将包含字符的文档的页面存储在未被识别为文字的文本段中。词识别机制分析页面的文本段，并将文本段作为文本对象存储在链表中。词识别机制通过分析文本对象进行分词，并通过使用与文本段相关联的位置数据来分析文本对象之间的间隙来识别链表中的文本对象中的单词。所识别的字被存储在单词列表中，并在必要时进行排序。本发明的方法从具有多个文本段和相关位置数据的文档的页面接收文本段，包括每个文本段的x和y坐标。为每个文本段创建文本对象，并将文本对象输入到链表中。然后通过分析用于分词的文本对象和通过使用相关联的位置数据分析文本对象之间的间隙来从链表中识别词。在文本对象中识别的单词被添加到单词列表中。重复上述步骤直到页面结束。该方法和装置可用于在便携式电子文档中搜索单词。

摘要： A computer implemented method includes receiving, by a computer, a plurality of objects, each object in the plurality having one or more associated attributes and an associated visual representation, wherein a sequential arrangement of the plurality of objects is specified based on the one or more associated attributes. The method includes defining a path according to a space-filling curve. The method includes determining that a visual representation of a first object in the sequential arrangement has a shape that is incompatible with a current position on the path. The method includes responsive to the determining, reordering the sequential arrangement, including assigning at least one visual representation of a second object to the current position on the path. The method includes assigning the visual representation of the first object to a subsequent position on the path with which the shape is compatible.

摘要： A method and apparatus for identifying words described in a page description file. A computer device stores a page description language file which includes characters that have not been identified as words by the page description language. A word identifying mechanism reads the page description language file and groups characters to form at least one word from the characters. The system preferably transfers words to a client process capable of processing words at a request of the client process. In a method for identifying words from a page description file, characters are read from the file and are stored in a word buffer until a word break is detected based upon character position data stored in the file. The contents of the word buffer are then provided to a client process as an identified word. The method can also sort the characters from the file into a display order prior to storing the characters in the word buffer. The method and apparatus can be used for searching for words in a page description file.
摘要翻译：一种用于识别在页面描述文件中描述的单词的方法和装置。计算机设备存储包括尚未被页面描述语言识别为字的字符的页面描述语言文件。字识别机制读取页面描述语言文件并组合字符以形成来自字符的至少一个单词。该系统优选地将单词传送到能够在客户端处理的请求下处理单词的客户端进程。在用于从页面描述文件中识别字的方法中，从文件中读取字符并存储在字缓冲器中，直到基于存储在该文件中的字符位置数据来检测到单词中断。然后将字缓冲器的内容作为识别字提供给客户端进程。在将字符存储在单词缓冲区之前，该方法还可以将文件中的字符排序为显示顺序。该方法和装置可用于搜索页面描述文件中的单词。
