Fill Transparency

To make a layer's fill completely transparent, set the Fill Transparency value to 0%, as shown in the figure below.

When Fill Transparency Is Set to 0%

The layer's fill becomes fully transparent, allowing the underlying map features to remain visible.

The result below shows the layer with a fully transparent fill, allowing the underlying map features to remain visible.

To make the layer fill fully opaque (non-transparent), set the Fill Transparency value to 100%.



The result below shows the layer with a fully opaque fill, as the Fill Transparency value is set to 100%.
