Image warp effect filter.

Namespace:  AForge.Imaging.Filters
Assembly:  AForge.Imaging (in AForge.Imaging.dll) Version: 2.2.5.0 (2.2.5.0)

Syntax

C#
public class ImageWarp : BaseFilter

Remarks

The image processing filter implements a warping filter, which sets pixels in destination image to values from source image taken with specified offset (see WarpMap).

The filter accepts 8 bpp grayscale images and 24/32 color images for processing.

Sample usage:

CopyC#
// build warp map
int width  = image.Width;
int height = image.Height;

IntPoint[,] warpMap = new IntPoint[height, width];

int size = 8;
int maxOffset = -size + 1;

for ( int y = 0; y < height; y++ )
{
    for ( int x = 0; x < width; x++ )
    {
        int dx = ( x / size ) * size - x;
        int dy = ( y / size ) * size - y;

        if ( dx + dy <= maxOffset )
        {
            dx = ( x / size + 1 ) * size - 1 - x;
        }

        warpMap[y, x] = new IntPoint( dx, dy );
    }
}
// create filter
ImageWarp filter = new ImageWarp( warpMap );
// apply the filter
Bitmap newImage = filter.Apply( image );
