# ImageMultiply

 ImageMultiply[image, x] multiplies each channel value in image by a factor x. ImageMultiply[image1, image2]gives an image in which each pixel is the product of the corresponding pixels in image1 and image2.
• The image returned by ImageMultiply[image, ...] has the same dimensions as image.
• 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.
• In ImageMultiply[image, x], the number x is normally in the range 0 to 1.
• ImageMultiply[image, x] gives an image with the same underlying data type as image, clipping or truncating values if necessary.
• ImageMultiply[image1, image2] gives an image with the largest type of either image1 and image2, clipping or truncating values if necessary.
• For binary images, ImageMultiply effectively finds the logical AND of pixel values.
