Default: 0.3

For text fields, if certain font metric information is unobtainable the “descender” length (distance from the font’s baseline to the bottom of its bounding box) needs to be estimated. This can be given here as a percentage of the overall font height. This value is used for vertical positioning of the text in the field.

This value is only used if the required font metric information is missing, and if appearance streams are being (re-)constructed. This parameter resides in the sub-dictionary named by the AcroFormParams parameter.
