附加信息

Blend modes are always the result of mathematical operations between layers behind the blended layer and the layer itself. In a map view, if the map background color is set to 'no color, then white is used for the blend operation. On a layout view, there can be multiple elements and other content behind the map frame. In order to continue to honor cases where users explicitly set the map frame background to transparent (no color) while remaining performant in an interactive layout view, the blend is performed in an isolated manner, operating only within the map frame itself. In this case (which is a single basemap layer in a map frame with a transparent background), the blend is performed with that transparent background color, which for effects such as luminosity results in no change to the color of the blended layer. If the desired behavior is to mimic the map view explicitly, then the map frame background color can be set to white to give the same appearance as the blend mode when applied to the map view.

解决办法

Set the map frame background to white to closely mimic the behavior of the map view. This can be done by unchecking the 'Use map background color' option for the 'Map Frame' section and setting the background fill color to white under the 'Display' tab.
