A device (10) and method for converting display information between graphics scales, e.g., between a 4:3 aspect ratio and a 16:9 aspect ratio. The method includes arcuately converting at least a portion of at least one dimension of display information between an arcuate format and a chordal or subtense format by scaling display information between the length of an arc length of a curve having a first endpoint and a second endpoint and a linear line segment of the arc length of the curve from the first endpoint to the second endpoint. For example, for a circular curve, arcuate conversion occurs between the length of an arc having a first endpoint and a second endpoint and the length of the chord or subtense of the arc from the first endpoint to the second endpoint. |
