C# Class AForge.Imaging.Filters.RotateNearestNeighbor

Rotate image using nearest neighbor algorithm.

The class implements image rotation filter using nearest neighbor algorithm, which does not assume any interpolation.

Rotation is performed in counterclockwise direction.

The filter accepts 8/16 bpp grayscale images and 24/48 bpp color image for processing.

Sample usage:

 // create filter - rotate for 30 degrees keeping original image size RotateNearestNeighbor filter = new RotateNearestNeighbor( 30, true ); // apply the filter Bitmap newImage = filter.Apply( image );
