Blend Layer Gradient Alpha

Scales the opacity of every stop in a blend-gradient at once. Valid values run from 0 to 100, and the default is 100.

It is a multiplier over the alpha each stop already carries, so a stop written as 80ffffff at blend-gradient-alpha=50 draws at 25% opacity. It is ignored when blend-gradient-mask is on.

This is separate from blend-alpha, which sets the opacity of the whole layer.

Use blend-gradient-alpha[N] to target a specific blend layer, where N is 0–3. Layer 0 is either the bare blend-gradient-alpha or blend-gradient-alpha[0]; if both are supplied, the bare name wins. A layer never borrows another layer’s spelling.
