Blend Size blend-size

Causes the overlay image to inherit the width, height, fit, and crop type of the base image. This parameter makes it easier to automate working with overlay images, resulting in the use of fewer parameters.

Note: bs is not applicable to color or text overlays—color overlays apply to the entire image, and there is no equivalent inheritance parameter for text.

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