    • Enum Constant Summary

      Enum Constants 
      Enum Constant Description
      BI_BITFIELDS
      The bitmap is not compressed and the color table consists of three DWORD color masks that specify the red, green, and blue components, respectively, of each pixel.
      BI_CMYK
      The image is an uncompressed CMYK format.
      BI_CMYKRLE4
      A CMYK format that uses RLE compression for bitmaps with 4 bits per pixel.
      BI_CMYKRLE8
      A CMYK format that uses RLE compression for bitmaps with 8 bits per pixel.
      BI_JPEG
      The image is a JPEG image, as specified in [JFIF].
      BI_PNG
      The image is a PNG image, as specified in [RFC2083].
      BI_RGB
      The bitmap is in uncompressed red green blue (RGB) format that is not compressed and does not use color masks.
      BI_RLE4
      An RGB format that uses RLE compression for bitmaps with 4 bits per pixel.
      BI_RLE8
      An RGB format that uses run-length encoding (RLE) compression for bitmaps with 8 bits per pixel.

      • BI_RGB

        public static final HwmfBitmapDib.Compression BI_RGB
        The bitmap is in uncompressed red green blue (RGB) format that is not compressed and does not use color masks.

      • BI_RLE8

        public static final HwmfBitmapDib.Compression BI_RLE8
        An RGB format that uses run-length encoding (RLE) compression for bitmaps with 8 bits per pixel. The compression uses a 2-byte format consisting of a count byte followed by a byte containing a color index.

      • BI_RLE4

        public static final HwmfBitmapDib.Compression BI_RLE4
        An RGB format that uses RLE compression for bitmaps with 4 bits per pixel. The compression uses a 2-byte format consisting of a count byte followed by two word-length color indexes.

      • BI_BITFIELDS

        public static final HwmfBitmapDib.Compression BI_BITFIELDS
        The bitmap is not compressed and the color table consists of three DWORD color masks that specify the red, green, and blue components, respectively, of each pixel. This is valid when used with 16 and 32-bits per pixel bitmaps.

      • BI_JPEG

        public static final HwmfBitmapDib.Compression BI_JPEG
        The image is a JPEG image, as specified in [JFIF]. This value SHOULD only be used in certain bitmap operations, such as JPEG pass-through. The application MUST query for the pass-through support, since not all devices support JPEG pass-through. Using non-RGB bitmaps MAY limit the portability of the metafile to other devices. For instance, display device contexts generally do not support this pass-through.

      • BI_PNG

        public static final HwmfBitmapDib.Compression BI_PNG
        The image is a PNG image, as specified in [RFC2083]. This value SHOULD only be used certain bitmap operations, such as JPEG/PNG pass-through. The application MUST query for the pass-through support, because not all devices support JPEG/PNG pass-through. Using non-RGB bitmaps MAY limit the portability of the metafile to other devices. For instance, display device contexts generally do not support this pass-through.

      • BI_CMYKRLE8

        public static final HwmfBitmapDib.Compression BI_CMYKRLE8
        A CMYK format that uses RLE compression for bitmaps with 8 bits per pixel. The compression uses a 2-byte format consisting of a count byte followed by a byte containing a color index.

      • BI_CMYKRLE4

        public static final HwmfBitmapDib.Compression BI_CMYKRLE4
        A CMYK format that uses RLE compression for bitmaps with 4 bits per pixel. The compression uses a 2-byte format consisting of a count byte followed by two word-length color indexes.

    • Method Detail

      • values

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

      • valueOf

        public static HwmfBitmapDib.Compression valueOf​(java.lang.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:
        java.lang.IllegalArgumentException - if this enum type has no constant with the specified name
        java.lang.NullPointerException - if the argument is null
