kdu_subband access_subband( int band_idx)
Java: Kdu_subband Access_subband( int band_idx)
[Declared in "../coresys/common/kdu_compressed.h"]
Returns an interface to a particular subband within the interal code-stream management machinery.
Must be LL_BAND if get_res_level returns 0. Otherwise, must be one of HL_BAND (horizontally high-pass), LH_BAND (vertically high-pass) or HH_BAND. Note that these are apparent subbands. If the transpose flag was supplied during a call to kdu_codestream::change_appearance, the roles of the LH and HL subbands will be automatically interchanged.
