Enum HwmfMapMode

  • All Implemented Interfaces:
    Serializable, Comparable<HwmfMapMode>
    public enum HwmfMapMode
extends Enum<HwmfMapMode>
    A 16-bit unsigned integer that defines the mapping mode. The MapMode defines how logical units are mapped to physical units; that is, assuming that the origins in both the logical and physical coordinate systems are at the same point on the drawing surface, what is the physical coordinate (x',y') that corresponds to logical coordinate (x,y). For example, suppose the mapping mode is MM_TEXT. Given the following definition of that mapping mode, and an origin (0,0) at the top left corner of the drawing surface, logical coordinate (4,5) would map to physical coordinate (4,5) in pixels. Now suppose the mapping mode is MM_LOENGLISH, with the same origin as the previous example. Given the following definition of that mapping mode, logical coordinate (4,-5) would map to physical coordinate (0.04,0.05) in inches.

    • Enum Constant Detail

      • MM_TEXT

        public static final HwmfMapMode MM_TEXT
        Each logical unit is mapped to one device pixel. Positive x is to the right; positive y is down.

      • MM_LOMETRIC

        public static final HwmfMapMode MM_LOMETRIC
        Each logical unit is mapped to 0.1 millimeter. Positive x is to the right; positive y is up.

      • MM_HIMETRIC

        public static final HwmfMapMode MM_HIMETRIC
        Each logical unit is mapped to 0.01 millimeter. Positive x is to the right; positive y is up.

      • MM_LOENGLISH

        public static final HwmfMapMode MM_LOENGLISH
        Each logical unit is mapped to 0.01 inch. Positive x is to the right; positive y is up.

      • MM_HIENGLISH

        public static final HwmfMapMode MM_HIENGLISH
        Each logical unit is mapped to 0.001 inch. Positive x is to the right; positive y is up.

      • MM_TWIPS

        public static final HwmfMapMode MM_TWIPS
        Each logical unit is mapped to one twentieth (1/20) of a point. In printing, a point is 1/72 of an inch; therefore, 1/20 of a point is 1/1440 of an inch. This unit is also known as a "twip". Positive x is to the right; positive y is up.

      • MM_ISOTROPIC

        public static final HwmfMapMode MM_ISOTROPIC
        Logical units are mapped to arbitrary device units with equally scaled axes; that is, one unit along the x-axis is equal to one unit along the y-axis. The META_SETWINDOWEXT and META_SETVIEWPORTEXT records specify the units and the orientation of the axes. The processing application SHOULD make adjustments as necessary to ensure the x and y units remain the same size. For example, when the window extent is set, the viewport SHOULD be adjusted to keep the units isotropic.

      • MM_ANISOTROPIC

        public static final HwmfMapMode MM_ANISOTROPIC
        Logical units are mapped to arbitrary units with arbitrarily scaled axes.

    • Field Detail

      • flag

        public final int flag
        native flag

      • scale

        public final int scale
        transformation units - usually scale relative to current dpi. when scale == 0, then don't scale when scale == -1, then scale relative to window dimension.

    • Method Detail

      • values

        public static HwmfMapMode[] 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 (HwmfMapMode c : HwmfMapMode.values())
    System.out.println(c);
        Returns:
        an array containing the constants of this enum type, in the order they are declared

      • valueOf

        public static HwmfMapMode 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
