This node joins an RGB and mono layer to create an RGBA layer. The mono layer contains the alpha.
Premultiply Alpha
Premultiplies the inputs to create an associated RGBA layer. When off, the node directly joins the RGB and alpha channels.
Note
RGBA layers are usually premultiplied.
rgb
The RGB layer to join.
alpha
The mono layer to join and use as an alpha channel.
rgba
The RGBA components. These might be premultiplied by alpha.
