mipMapDescriptions

public List<CLNImageArrayDescription> mipMapDescriptions()
                                                  throws IOException

Specified by:

mipMapDescriptions in interface CLNSectionReadableImageArrayType

Returns:

The set of declared mipmaps

Throws:

IOException - On errors

mipMapDataWithoutSupercompression

public ReadableByteChannel mipMapDataWithoutSupercompression(CLNImageArrayDescription description)
                                                      throws IOException

Specified by:

mipMapDataWithoutSupercompression in interface CLNSectionReadableImageArrayType

Parameters:

description - The image description

Returns:

A readable channel
