Abstract: When the device is rotated from a portrait orientation to landscape orientation, or vice versa, the display device rotates the content items within distinct respective content regions of a page template (“slots”) that each appear to stay in their same position with respect to a frame of reference of the display device. While the content regions stay in their same positions, the content within each content region counter-rotates in place to offset the rotation of the display device. Thus, the content within the content regions maintains an orientation with respect to a constant (non-rotating) frame of reference, regardless of the orientation or rotation of the display device. In one embodiment, a slot's position, height, and width in a template in a second orientation are determined from the slot's position, height, and width in the template in a first orientation.

Abstract: A device includes a character-data rotating section that rotates a regular-position character by a predetermined angle with respect to a reference point that is the center point of the background area of the regular-position character by using regular-position character data having a rotation angle of 0° and a center-point matching processing section that horizontally and/or vertically enlarges the background area of the rotated character data to cause the center point of the rotated character and the center point of BMP data to match each other even with respect to rotated character data. Thus, when multiple pieces of character data are arranged so that the center points thereof lie on a reference line, not only are the center points of the characters aligned along the reference line, but also bottom portions of the characters aligned with respect to the reference line.

Abstract: A map editing system for processing map data in order to reduce discrepancies between geometric objects in the map data through the use of a cost function. The system selects a polygon shaped object (e.g., a park) for processing. The polygon may be located close to several polyline objects (e.g., streets) or other polygon objects so that discrepancies, such as open spaces, appear between the objects when displayed together in a map. To eliminate these discrepancies while maintaining the overall appearance of the polygon, the system repeatedly adjusts the border of the polygon until the attributes of the polygon minimize a cost function.

The method comprises a first determination of perspectively correct texture address values found at four corners of a predefined span or grid of pixels.

Every UN sample coincides with four (2×2) Y samples. This is identical to the organization of texels in U.S. Pat. No.
