      Converts value to pixels.

      Parameters

      • value: The value to be converted.

      • unit: The unit of value. Never null and at least one character.

      • refValue: @param refValue Some reference value that may of may not be used. If the unit is percent for instance this value is the value to take the percent from. Usually the size of the parent component in the appropriate dimension.

      • isHor: If the value is horizontal (true) or vertical (false).

      • parent: @param parent The parent of the target component that value is to be applied to. Might for instance be needed to get the screen that the component is on in a multi screen environment.

      May be null in which case a "best guess" value should be returned.

      • comp: The component, if applicable, or null if none.
      Returns

      The number of pixels if unit is handled by this converter, UnitConverter.UNABLE if not.
