multiplies each channel value in image by a factor x.


gives an image in which each pixel is the product of the corresponding pixels in image1 and image2.


multiplies all expri with image, where each expri can be either an image, a number, or a color value.


  • The image returned by ImageMultiply[image,] has the same dimensions as image.
  • In ImageMultiply[image,x], x can be a number normally in the range 0 to 1, a color, or a list of color channel values.
  • ImageMultiply[image,x] typically gives an image with the same underlying data type as image, clipping or truncating values if necessary. »
  • If the image dimensions are different, ImageMultiply[image1,image2] multiplies image2 into the center of image1.
  • If image1 or image2 is a single-channel image, its values are multiplied by the values in each channel of the other image in ImageMultiply[image1,image2].
  • If image1 and image2 are both multichannel images, the values in each channel are multiplied separately.
  • ImageMultiply[image1,image2] gives an image with the largest type of either image1 or image2, clipping or truncating values if necessary.
  • For binary images, ImageMultiply effectively finds the logical AND of pixel values.
  • ImageMultiply[image,expr1,expr2,] folds ImageMultiply on the list of arguments.
  • ImageMultiply[{image,expr1,expr2,}] is equivalent to ImageMultiply[image,expr1,expr2,].
  • ImageMultiply works with Image3D objects.
