Layers Dialog / Layer Blending Modes

§ 19.6.11 - PCB Blend Modes

§ 19.6.11.1 - PCB Copper

PCB (printed circuit board) Copper layers are transparent where no RGB color component is below 1/2 intensity. The alpha channel is ignored. The Opacity control can adjust the transparency of the layer.

Tip: To get more than one copper layer to show through each other in the master image, adjust the Opacity control for the copper layers in the Layers dialog.

PCB layer modes cannot incorporate positional offsets.

Note: Because the Gerber file CAM files are bi-level, there's no such thing as a partially-on level, no matter what. So when working on printed circuit board layer types, areatool antialiasing does not function, regardless of the actual setting of antialiasing for the particular areatool in use.
