Blend Width

Sets the width of the overlay image.

This operation occurs after your initial image has been resized. Values can range from 0 to the width of the overlay image, and can be larger than the width of the base image if desired.

When the value is a positive integer greater than 1, the value is interpreted as a pixel width. When the value is a float between 0.0 and 1.0, the value is interpreted as a ratio to the resized base image width. Parameter blend-fit will control how the overlay image is fit to its blend-w.

Note: blend-w 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.
