Blend Width blend-w

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. 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.

See the API specification for more information about this parameter's value ranges and format.
