Constructor Detail

BufferedImageUtilities

public BufferedImageUtilities()

Method Detail

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

public static String transferTypeName(int bufferType)

typeName

public static String typeName(ColorSpace space)

Return name for its color-space type.

Parameters:

space -
