Image rotation with substantially no aliasing error

A method of rotating a first image in an image buffer, the method comprising the steps of:

• extracting first image from the image buffer;
• creating a rotated image that is substantially free of aliasing error using weighted sums of a plurality of data points of the first image that represent pixel data values of the first image, wherein weighting depends on a skew angle of the first image and data point location in the first image;
• and
• outputting the rotated image from the image buffer,
• wherein the step of creating the rotated image is provided by applying the following algorithm to the first image data:
• V0=Kh*Kv (V1+V4−V2−V3)+Kh (V3−V4)+Kv (V2−V4)+V4
• wherein V0 is a data point of the rotated image;
• V1, V2, V3 and V4 are data points of the first image data points that each incorporated a portion of V0;
• and Kh and Kv are fractions that are functions of skew angle and data point location of the first image.
