Add fillter - add pixel values of two images.

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


public sealed class Add : BaseInPlaceFilter2


The add filter takes two images (source and overlay images) of the same size and pixel format and produces an image, where each pixel equals to the sum value of corresponding pixels from provided images (if sum is greater than maximum allowed value, 255 or 65535, then it is truncated to that maximum).

The filter accepts 8 and 16 bpp grayscale images and 24, 32, 48 and 64 bpp color images for processing.

Sample usage:

// create filter
Add filter = new Add( overlayImage );
// apply the filter
Bitmap resultImage = filter.Apply( sourceImage );
