  • Constructor Details

    • BufferedImageUtilities

      public BufferedImageUtilities()

  • Method Details

    • typeName

      public static String typeName(int imageType)
      Return name for given BufferedImage type.

    • typeName

      public static String typeName(int imageType, BufferedImage image)

      Return name for integer type and/or for BufferedImage's actual type.

      If image is null, then name is for imageType alone.

      If image is non-null, and its type matches imageType, then name is for imageType alone.

      If image's type doesn't match imageType, then name is first for imageType, followed by image's actual type name in parentheses.

      Parameters:
      imageType -
      image -
      Returns:
      String name

    • transferTypeName

    • typeName

      public static String typeName(ColorSpace space)

      Return name for its color-space type.

      Parameters:
      space -
      Returns:
      String name
