Underlay Layer

Use the Underlay Layer effect to read only the Underlay layer in an element. Place a Underlay Layer module after a drawing module in the Network view to display only the module's Underlay layer output. The Underlay Layer module can only be connected after a vector drawing layer or a vector type Composite module. Any bitmap information will not be processed.

This effect will only work if the user drew or painted something into the Underlay layer of the drawing.

Use the Underlay Layer editor to control how the Underlay layer is rendered by the module.

Antialiasing Quality: Smoothness setting applied to the Underlay layer. Choose from Low (no antialiasing), Medium Low, Medium and High (extensive antialiasing). The higher the quality of the chosen setting, the greater the amount of antialiasing that is applied. Higher quality images require more time to render and more memory from your system.
Antialiasing Exponent: Controls the amount of area around the Underlay layer edges that is used in the antialiasing process. A higher value uses less area, resulting in sharper edges, while a lower value uses more area, resulting in softer edges. If the Antialiasing Quality value is set to Low (no antialiasing), this value is ignored.
