For multi-line text fields with automatic font scaling (such as, font scale given as zero in the /DA entry of the field dictionary), a maximum and a minimum range plus an “incremental” value are needed by the scaling algorithm used to adjust the font scale each time it tries to fit the text within the field. The Max and Min values are direct font scale values while the MultiLineAutoFontScaleIncr value is the percentage by which the algorithm adjusts the font scale each time it tries to fit the text. These parameters are only acted upon if appearance streams are being (re-)constructed. These parameters reside in the sub-dictionary named by the AcroFormParams parameter.
