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.

摘要： Une représentation des contours d'un caractère ou d'un symbole est traitée comme étant composée d'une hiérarchie de zones dans les sens horizontal et vertical. Les zones sont tout à fait spécifiques aux caractères. Chaque zone définit l'étendue d'un trait particulier du caractère. Les limites des zones sont attribuées à des points spécifiques dans un cadratin en mode point ayant une résolution et des dimensions sélectionnées. Les points disponibles sont alors alloués aux zones. Une fois que chaque niveau de zone a reçu son allocation de point, les points ainsi assignés sont distribués parmi le prochain niveau inférieur de zone et le processus se répète itérativement jusqu'à ce que toutes les zones aient reçu leurs allocations de points ou qu'il ne soit plus possible d'allouer des points. Afin de maintenir des relations entre certains traits particuliers, les traits particuliers des caractères (aussi bien à l'intérieur de caractères individuels qu'entre différents caractères) peuvent être reliés de façon à être définis en termes des traits particuliers du même caractère ou d'autres caractères. Les traits particuliers sont reliés au niveau de la description des contours, de sorte que leur liaison ne doive être spécifiée qu'une seule fois et soit utile par la suite à chaque fois que l'on veut générer un graphique en mode point à partir du contour.

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： A system rapidly rasterizes high resolution shapes, such as outline fonts, for use in a lower resolution pixel image. For individual pixels a line coverage value is determined for each of at least two sampling lines running in different directions, such as at right angles, within the pixel. The pixel's line coverage value for each line is a function of the degree to which the line is covered by any shapes within the pixel. Then a coverage value is determined for the pixel, itself, as a non-linear function of it's one or more line coverage values running in each of the different directions. Commonly the non-linear function causes the pixel's coverage value to vary more rapidly with variations in the line coverage value of that one of its sampling line which is closest to being half covered within the pixel. Such rasterization can be performed even more rapidly by using two passes, a first which calculates a pixel coverage value for all pixels as a function of the coverage within each pixel of one or more lines of the first set of parallel lines which run in a first direction, and a second pass which varies the pixel coverage value set in the first pass only if there is an intersection between the outline of a shape being rendered and a one or more lines of the second set of parallel lines which run in a second direction.
