Abstract
One embodiment of an embedded device comprises an angle of rotation defining mechanism and a rotation mechanism. The angle of rotation defining mechanism is adapted to define an arbitrary angle of rotation for an image. The rotation mechanism is adapted to apply a rotation transformation angle to the image using the arbitrary and using only integer arithmetic such that pixels within the image are mapped to rotated positions.
Claims29
An embedded device, comprising:
- an angle of rotation defining mechanism to define an angle of rotation for an image;
- and
- a rotation mechanism to apply a rotation transformation to the image using the angle and using only integer arithmetic such that pixels within the image are mapped to rotated positions.
A machine-readable medium encoded with data, the data being interoperable with a machine to cause:
- defining an angle of rotation for an image;
- and
- applying a rotation transformation using the angle to the image using only integer arithmetic such that pixels within the image are mapped to rotated positions.
Apparatus comprising:
- an embedded device;
- means within the embedded device for defining an angle of rotation for an image;
- and
- means within the embedded device for applying a rotation transformation using the angle to the image using only integer arithmetic such that pixels within the image are mapped to rotated positions.
