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.
ImageMultiply [image,expr1,expr2,…]
multiplies all expri with image, where each expri can be either an image, a number, or a color value.

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.
ImageMultiply [image,expr1,expr2,…]
multiplies all expri with image, where each expri can be either an image, a number, or a color value.
Details
- 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.
