摘要： 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.
摘要翻译：公开了一种用于优化开放式字体设计中上标和下标的水平间距的方法和系统。该系统包括用于垂直对齐和间隔字符的模块和用于根据存储在与字体中的每个单独字符相对应的字体表中的切入信息水平对准具有不同基线的字符的模块。这种额外的水平间距调整能力提供了具有不同基线（例如上标或下标）的字符字形的最佳放置。该方法包括将第一/下一个字符放置在基线上，检索下一个相邻字符，确定是否可以在两个字符之间应用与一个或两个字符相关联的剪切，然后应用适当的切入。确定剪切是否适用可以通过评估相邻字形边界框的相对位置来实现。

摘要： Methods and systems provide a “tree view” for a markup language referred to as Reusable Data Markup Language (“RDML”). Generally, a tree view comprises the components necessary for automatically manipulating and displaying a graphical display of numerical data contained in RDML markup documents. RDML is a markup language, such as the Hypertext Markup Language (“HTML”) or the Extensible Markup Language (“XML”). Generally, RDML facilitates the browsing and manipulation of numbers, as opposed to text as in HTML, and does so by requiring attributes describing the meaning of the numbers to be attached to the numbers. Upon receiving RDML markup documents, the tree view transforms, formats, manipulates and displays data stored in the markup documents using the attributes describing the meaning of the data. The tree view uses the attributes of the numbers to, for example, facilitate the simultaneous display of different series of numbers of different types on a single display. It automatically displays the relationship between series of numbers while displaying appropriate labels, titles, number precision, etc. A tree view may be a component of a data viewer used to retrieve, manipulate, and view documents in the RDML format.

摘要： Systems and methods for automatically building up an equation entered into a computer system can include an input module that accepts input of the equation in a linear string format, and an interpret module that interprets the input and automatically determines when a buildup point is reached. Systems can further include a formatting module that, upon reaching the buildup point, automatically formats at least a portion of the equation into a two-dimensional format. A display module can display the portion of the equation in the two-dimensional format. A revision module allows the equation to be edited.

摘要： A character processing apparatus for arbitrarily setting a character pitch when a mathematical formula is input. This apparatus includes: a memory to store character patterns corresponding to character pitches; a keyboard to input character information to read out the character pattern to be displayed from the memory; a display device to display at least the character patterns; a designating device to designate the character pitch of the character pattern to be displayed; a cursor display device for changing the display form of the cursor to designate the display position to display the character pattern in correspondence to the character pitch designated by the designating device, and for displaying the changed display form; and a display controller which, when the character information is input by the keyboard, reads out the character pattern corresponding to the character information from the memory at the display position of the cursor displayed by the cursor display device on the basis of the character pitch corresponding to the cursor display form. With this apparatus, the character pitch and line interval are adjusted. When a mathematical formula is input, the character string constituting this formula can be displayed and printed with a good balance.

摘要： A mathematical expression input apparatus which is capable of inputting and displaying a mathematical expression efficiently by automatically determining whether or not an element inputted to a displayed input position of a functional expression can be recognized as a complete argument without instructions from the user. In the case of inputting an exponent of a power calculation, it is determined that the input of the argument is complete when a predetermined number of digits such as the second digit is inputted in an exponent display position thereby automatically moving a cursor from the exponent display position to a normal display line position. In addition, for example, in the input of an element in a root symbol where a left bracket is first inputted. It is then determined that the input of the argument is ended with the input of a right bracket which automatically moves the cursor from the inside of the root symbol to the normal display line position adjacent to the root symbol. Thus the cursor is automatically moved in the respective situations to the normal display line position without an additional instruction from the user.
摘要翻译：一种数学表达式输入装置，其能够通过自动确定输入到功能表达式的所显示的输入位置的元素是否能够被识别为完整的参数而无需来自用户的指令，来有效地输入和显示数学表达。在输入功率计算的指数的情况下，当在指数显示位置中输入预定数量的数字（例如第二数字）时，确定参数的输入完成，从而从指数显示器自动移动光标位置到正常显示行位置。此外，例如，在输入左括号的根符号中的元素的输入中。然后确定参数的输入结束，右框的输入自动地将光标从根符号的内部移动到与根符号相邻的正常显示行位置。因此，光标在各种情况下自动地移动到正常显示行位置，而没有来自用户的附加指令。

摘要： A method and apparatus carried out on a digital computer for creating and editing mathematical equations in a printed document is disclosed. This invention allows the user of a wordprocessing program to create and edit mathematical equations in an efficient and flexible manner through use of a user interface which includes an editing window, a display window, and a palette window. The editing window allows the user to input a textual description of the equation, the palette window provides an alternative method of entering the textual description of the equation by displaying the characters and commands that may be used, and the display window displays the equation as it appears in its final printed form. The textual description for an equation is entered by the user through keyboard characters, extended characters, and by selecting editing commands and characters from the palette window, and the method and apparatus of the present invention processes the textual description and provides simultaneous visual representations of both the textual descriptions and the equations as they will appear in the final printed form.
