public abstract ScaleFactor calculate(Optional<Dimensions> dimensionsToBeScaled,
 Optional<ImageSizeSuggestion> suggestedSize)
                               throws OperationFailedException

Calculates a scaling-factor for a source image/entity of particular dimensions.

Parameters:

dimensionsToBeScaled - dimensions of the source image/entity that will be scaled, if they are known.

suggestedSize - a string suggesting dimensions to resize to or a scaling-factor.

Returns:

the scaling-factor to use.

Throws:

OperationFailedException - if a scale-factor cannot be successfully calculated.
