results in no change; multiplying by black, 0.0, results in black).</p>
<p>Since the alpha channel is also multiplied, a fully-transparent pixel
(opacity 0.0) in one image results in a fully transparent pixel in the
output. This is similar to <a href="dart-ui/BlendMode-class.html">dstIn</a>, but with the colors combined.</p>
<p>For a variant that multiplies the colors but does not multiply the alpha
channel, consider <a href="dart-ui/BlendMode-class.html">modulate</a>.</p>
