Blend Padding

Sets the number of pixels of padding around the overlay image when blend-align (Blend Align) is set. Use blend-pad[N] to style a specific additional blend layer — styles do not inherit across blend layers.

Note: blend-pad is not applicable to color or text overlays—color overlays apply to the entire image, and text overlay padding can be controlled with the txt-pad parameter.

This parameter accepts a relative length: a whole number is pixels, and a decimal between 0 and 1 is a fraction of the base image, taken per axis.
