# vImage.BlendMode.multiply Sets the destination pixel as the product of the corresponding source pixels. ``` case multiply ``` ## Discussion The following image shows the result of compositing using the multiply blend mode:  The bottom-right quadrant in the result is black because the operation multiplies each bottom-layer pixel value by `0.0` from the top layer. The top-left quadrant in the result is identical to the corresponding quadrant in the bottom layer because the operation multiplies each bottom-layer pixel value by `1.0`. The top-right quadrant in the result is darker than the corresponding quadrant in the bottom layer. In this quadrant, the top-layer and bottom-layer pixel values are identical. For example, if the source pixel value is 0.5, the destination pixel value is `0.25`: ```swift dest = 0.5 * 0.5 // dest = 0.25 ``` ## See Also --- Copyright © 2026 Apple Inc.
