C# Class AForge.Imaging.Filters.RotateBicubic

Rotate image using bicubic interpolation.

The class implements image rotation filter using bicubic interpolation algorithm. It uses bicubic kernel W(x) as described on Wikipedia (coefficient a is set to -0.5).

Rotation is performed in counterclockwise direction.

The filter accepts 8 bpp grayscale images and 24 bpp color images for processing.

Sample usage:

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