Setting layer transparency
Transparency can be used for any symbolization type, but it is especially useful for drawing raster layers with other layers on your map. Adding transparency to the top layers allows you to see them while still viewing underlying layers.
You can set layer transparency on the Display tab on the Layer Properties dialog box.
You can also set layer transparency using the Effects toolbar as described in the following steps:
- Click Customize > Toolbars > Effects on the main menu.
- Click the layer drop-down arrow and select the layer that you want to appear transparent.
Click the Adjust Transparency button and drag the slider bar to adjust the transparency.
The Effects toolbar appears.
- For layers using a single symbol or for layers displayed by category, you can set the transparency of individual features using field values to set percent transparency.
- You can set transparency for group layers. In these cases, it will take into account the transparency settings of each sublayer in the overall group layer transparency.
- You can use the Swipe Layer tool and Flicker Layer command on the Effects toolbar to interactively reveal what is underneath a particular layer.
