摘要： A bitmap of a shape, such as a font, can be subpixel optimized by producing for each of a display's subpixels a coverage value representing the percent of its area covered by the shape being represented and by distributing, to prevent color imbalance, an amount of a given subpixel's coverage value to nearby subpixels of different colors as a function of the percent of the given subpixel's coverage value that causes color imbalance. Web pages can be displayed with scaled-down and subpixel optimized images. A given layout of a Web page can be displayed at each of at least two different selected scale factors, with the font bitmaps used to represent characters in the display at each scale factor having their shape and pixel alignment selected to improve readability for the particular pixel size at which they are displayed at each such scale factor.

摘要： A computer system includes a requesting computer which asks a responding computer, such as an Internet server, for one or more portions of text. The responding computer reacts by sending the requested text. The requesting computer can either render the requested text without the text's font shapes, or it can ask the responding computer to send descriptions of such shapes, and then render the text using them. Preferably the font descriptions sent are grouped into sets, or portable font resources ("PFR"); each text sent identifies the one or more PFRs needed to define its font shapes; and the requesting computer asks for PFRs identified in texts it receives. The fonts and characters within fonts represented by each PFR vary as a function of its associated text. For each character to be rendered, the requesting computer finds which PFR associated with the character's text describes its shape, and uses that font description to render that shape. The responding computer can install such new font descriptions into its operating system, so character shapes can be rapidly rendered by standard operating system calls. The responding computer can translate a text's pre-defined font description into new font descriptions which depend only on character-font shapes. The responding computer can receive a changed body of text and a corresponding old set of PFRs, and derive a new set of one or more PFRs as a function of which character-font shapes occur in the changed text.

摘要： An outline representation of a character or symbol is treated as being composed of a set of zones formed in both the horizontal and vertical directions. The zones are completely character-specific. Each zone defines the extent of some feature of the character. The boundaries of the zones are mapped to specific pixel locations in a bitmap em-square of selected resolution and size. Additional interpolation zones are defined which are used to map all the points on the outline representation of the character that are contained within the interpolation zone, but do not coincide with a control edge, from the positions in the high-resolution em-square to a corresponding position in the low-resolution em-square. To maintain relationships between features, constraint functions may be defined which regulate the size of the control zones for a character at predetermined sizes. Control zones and interpolation zones are all derivatively linked to a basic set of horizontal and vertical control edges at the outline description level. Consequently, the number of computations needed is reduced and the speed with which a bitmap can be generated from the outline representation is increased.

摘要： A system and data structure for generating bitmap representations of characters and symbols from their outline representations. The outline representation is treated as being composed of a hierarchy of zones formed in both the horizontal and vertical directions. The zones are completely character-specific. Each zone defines the extent of some feature of the character. The zonal definition of the character comprises part of the information in the data structure. In generating the bitmap, the boundaries of the zones are mapped to specific pixel locations in a bitmap em-square of selected resolution and size. The available pixels are then allocated to the zones. After each level of zone has received its pixel allocation, the pixels assigned thereto are then distributed among the next lower level of zones and the process is repeated iteratively until all zones have received their pixel allocations or it is no longer possible to make allocations. To maintain relationships between features, features of characters (both within individual characters and between different characters) may be linked in the data structure so as to be defined in terms of the features of the same or other characters. The features are linked at the outline description level, so that the linking need be specified only once and will thereafter be useful any time a bitmap is to be generated from the outline.

摘要： Web pages are displayed with a simultaneous overview (19200A)and magnified view (19400A). An indicator (19504) can show the portion of the overview in the magnified view. Both views can be shown, one above the other, across the full width of the same screen. A user can select between such a split view and another view, including an overview-only view, a magnified-only view, and a view in which selected text is laid out to fit the width of the magnified view. Navigational input can directly move the layout in the magnified view or the cursor, and can scroll both the overview and magnified view. The magnified view can display text with antialiased fonts designed for its resolution. The magnified view can be made to function like a magnifying glass. The width of text in multicolumn layouts can be limited to fit the width of a view window, such as the magnified-view.

摘要： A method of producing a sub pixel resolution representation of a shape suitable for display on a sub pixel addressed screen. The method comprises producing a scaled sub pixel optimized image of a bitmap image by associating a luminosity value with each sub pixel of the scaled image as a function of the percent of the area of the sub pixel's area in the image that is covered by the shape and a color balancing function designed to distribute a portion of a sub pixel's luminosity value that otherwise would cause color imbalance to nearby sub pixels of different colors. The percent of a sub pixel's luminosity values that is so distributed is a function of the percent of the sub pixel's luminosity value, which causes color imbalance. An advantage is that it reduces the amount of luminosity value distributed for color balance purposes to approximately only that amount which is necessary to achieve color balance, and increases the clarity of sub pixel optimized images.

摘要： The invention relates to methods, systems, and programming for displaying media in a scaled manner and/or in an orientation other than an operating system displays its graphical user interface. Some embodiments lay out digital content at a virtual pixel resolution and then display a portion of the layout at a smaller display resolution by displaying images and text at scaled-down coordinates and scaled-down sizes, with the display of text being composed from a plurality of font bitmaps having character shapes and pixel alignments selected to improve readability at the scaled-down size. Some embodiments, which operate on computing systems having operating systems that display a graphical user interface in a portrait orientation, display a scaled-down representation of a web page in a landscape orientation, including displaying in such a landscape orientation scaled-down images and scaled-down text composed from a plurality of font bitmaps designed for the scaled-down size.
