Abstract:
A method for displaying text aligned in a virtual Cartesian grid on a radial display comprising:(a) converting a range bin value location on a scan line from a polar coordinate value to a rectangular coordinate value; (b) locating a virtual text grid location corresponding to the rectangular coordinate value; (c) determining a character and attributes of the character assigned to the virtual text grid location; (d) determining a pixel location within the virtual text grid location based on the font matrix of the character assigned to the virtual grid location; (e) associating the range bin value location with an attribute of the character based on the content of the pixel location; (f) repeating the steps of a through e for each range bin value location along a given scan line; (g) repeating the steps a through f for each scan line position; and (h) display the text on the radial display based on the polar coordinates of the range bin values and the associated attributes.
