Abstract: A system and method for selecting a power efficient network interface are provided. One or more network interfaces for data transfer are detected on an electronic device. An active network interface from the one or more network interfaces, where the active network interface is active for data transfer, is identified. One or more power profiles corresponding to the one or more network interfaces are obtained. A power efficient network interface for data transfer from the one or more network interfaces based on the one or more obtained power profiles is determined. In a case where the determined power efficient network interface is not the active network interface, the power efficient network interface is activated for data transfer; data transfer by the active network interface is suspended after the power efficient network interface has been activated.

Abstract: In one aspect, the present disclosure can be embodied in a method that includes dividing a Bezier curve representing a portion of a vector image to be rendered on a display of a computing device into a set of curve segments. Each of the curve segments is approximated using a circular arc from a set of circular arcs. An approximation error for each of the curve segments is determined. A spring constant is calculated as a function of the respective approximation error determined for each of the curve segments in the set of curve segments. The spring constant represents a relative magnitude of the respective approximation errors calculated for the approximated curve segments. The lengths of curve segments are adjusted based on the respective spring constant calculated for each curve segment in the set of curve segments.

Abstract: In one aspect, the subject disclosure can be embodied in a method for rendering glyphs using circular arcs. A first Bezier curve defining a portion of a glyph outline is approximated using a second Bezier curve that represents a Bezier approximation of a circular arc. An upper bound for the approximation error is estimated based on a maximum distance between the two Bezier curves within a two-dimensional coordinate space. The first Bezier curve is converted to the circular arc approximated using the second Bezier curve for the portion of the glyph outline within the two-dimensional coordinate space, based on the estimated upper bound of the approximation error. The portion of the glyph outline is then displayed within an area of the display.

Abstract: In one aspect, the present disclosure can be embodied in a method that includes approximating an outline of a vector image using a set of circular arcs. A signed distance value is computed for a selected group of points in a two-dimensional grid associated with the vector image based on a location of each point relative to the approximated outline of the vector image. The nearest are from the respective location of each point in the selected group is identified and the corresponding signed distance value is assigned to each point. The vector image is reproduced based on the signed distance value assigned to each point in the selected group.

Abstract: A system and method for modifying content display size on an electronic device that includes a touchscreen are provided. A multi-tap interaction with a touchscreen of the electronic device, the multi-tap interaction including plural presses, where each press of the plural presses occurs at a different time, such that a previous of the plural presses completes before a subsequent of the plural presses begins, is detected on the touchscreen electronic device. A determination of whether the last of the plural presses is maintained for at least a predetermined amount of time is made. In case where the last press is maintained for at least the predetermined amount of time, modification of the content display size for the touchscreen is activated, a slide interaction with the touchscreen is detected, and content display size for the touchscreen is modified in response to the detected slide interaction with the touchscreen.
