 ImageAdd adds an amount x to each channel value in image. ImageAddgives an image in which each pixel is the sum of the corresponding pixels in and .
• The image returned by ImageAdd has the same dimensions as image.
• If the image dimensions are different, ImageAdd adds at the center of .
• If or is a single-channel image, its values are added to the values in each channel of the other image in ImageAdd.
• If and are both multichannel images, the values in each channel are added separately.
• In ImageAdd, the number x is normally in the range 0 to 1.
• ImageAdd gives an image with the same underlying data type as image, clipping or truncating values if necessary.
• ImageAdd gives an image with the largest type of either or , clipping or truncating values if necessary.
• For binary images, ImageAdd effectively finds the logical OR of pixel values.
