Blend Align blend-align

Adjusts the alignment of the overlay image relative to the base image.

Valid values are top, middle, bottom, left, center, and right. Multiple values can be used when separated by a comma. Note: blend-align is not applicable to color or text overlays—color overlays apply to the entire image, and text overlay positioning can be controlled with the txt-align parameter.

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