Replace Transparent Alpha Values With Constant?

If this option is checked, the transparency of already transparent pixels will be replaced by the constant defined in the 'Constant Alpha Replacement Value' Number Selection.

Constant Alpha Replacement Value

The replacement value for transparent alpha values. Setting this value to 255 will remove the alpha channel from the image.

This node will create an ImgPlus with 4 color channels only if there are transparent pixels in the png's alpha channel. Otherwise the resulting PNG will only have the 3 color channels.
