Enum GridRoundingMode

    • Enum Constant Detail

      • NEAREST

        public static final GridRoundingMode NEAREST
        Converts grid low, high and size to nearest integer values. This mode applies the following steps:
        1. Floating point values are converted to integers with Math​.round(double).
        2. On the three integer values (low, high and size) obtained after rounding, add or subtract 1 to the value which is farthest from an integer value in order to keep unchanged the two values that are closer to integers.
        Example: the [lowhigh] range may be slightly larger than desired in some rounding error situations. For example if low before rounding was 1.49999 and high before rounding was 2.50001, then the range after rounding will be [1…3] while the expected size is actually only 2 pixels. This NEAREST rounding mode detects those rounding issues by comparing the size before and after rounding. In this example, the size is 2.00002 pixels, which is closer to an integer value than the low and high values. Consequently this NEAREST mode will rather adjust low or high (depending which one is farthest from integer values) in order to keep size at its closest integer value, which is 2.

      • values

        public static GridRoundingMode[] values()
        Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:
        for (GridRoundingMode c : GridRoundingMode.values())
            System.out.println(c);
        
        Returns:
        an array containing the constants of this enum type, in the order they are declared
      • valueOf

        public static GridRoundingMode valueOf​(String name)
        Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)
        Parameters:
        name - the name of the enum constant to be returned.
        Returns:
        the enum constant with the specified name
        Throws:
        Illegal­Argument­Exception - if this enum type has no constant with the specified name
        Null­Pointer­Exception - if the argument is null
