Abstract: Stroke contrast is preserved for a range of font sizes and display resolutions using programmatic constraints or “hints”. One implementation of a “font hinting” approach enforces a regularization of stroke weights such that stroke contrast is preserved for font sizes and display resolutions sufficient to render it. Font hinting instructions determine a stroke contrast threshold, which may be used to decide whether to preserve or omit stroke contrast when rendering the glyph. In one implementation, the stroke contrast threshold is based on one or more stroke contrast relationships associated with the typeface. In other implementations, the stroke contrast threshold is based on a minimum size threshold or lowercase/uppercase stroke contrast relationships.

Examples include changing the position, size and/or layout of the input elements and/or graphical input region. The graphical input elements may instead be provided with two characters so that typing one character results in input of the corresponding character, and then changing the association of the characters on the displayed input elements.

Abstract: A method and system of operating a remote terminal by a terminal server caches representation data of glyphs to be displayed on the remote terminal to reduce the amount of glyph data that have to be transmitted to the remote terminal through a network connection. The glyph caching is performed on a level of text fragments each of which includes a plurality of glyphs.

When the terminal server receives a request to display a text fragment on the remote terminal, it checks whether that fragment is cached at the remote terminal. If so, the terminal server sends a fragment index to the client identifying the entry in the fragment cache for that fragment.

In one embodiment, the inventive technique leverages the wider diagonal (in device dimensions) for text viewing and combine this form of display with a horizontal (in text dimensions) scrolling feature i.e. scrolling text along the diagonal of the device's display. Vertical context (in text dimensions) is maintained by adding a constant-offset look-ahead and look-back line above the primary diagonal focus area. Another embodiment bends the text along two edges of the display area to leverage the fact that the lengths of the two sides are even longer than the length of the screen diagonal. In both configurations, one can retain a large font size without sacrificing the number of characters displayed per line.

Otherwise the open font is compiled into compiled font code and cached, and the now-cached compiled font code is referenced.
