+
+ Add capability to decode only a subset of all components of an image.
+
+ This adds a opj_set_decoded_components(opj_codec_t *p_codec,
+ OPJ_UINT32 numcomps, const OPJ_UINT32* comps_indices) function,
+ and equivalent "opj_decompress -c compno[,compno]*" option.
+
+ When specified, neither the MCT transform nor JP2 channel transformations
+ will be applied.
+
+ Tests added for various combinations of whole image vs tiled-based decoding,
+ full or reduced resolution, use of decode area or not.

Optimize reading/write into sparse array
+commit 0ae3cba3404674bbe2028ea9a801301a4c951b33

+
+ Allow several repeated calls to opj_set_decode_area() and opj_decode() for single-tiled images
+
+ * Only works for single-tiled images --> will error out cleanly, as currently
+ in other cases
+ * Save re-reading the codestream for the tile, and re-use code-blocks of the
+ previous decoding pass.
+ * Future improvements might involve improving opj_decompress, and the image writing logic,
+ to use this strategy.

+
+ Untested though, since that means a tile buffer of at least 16 GB. So

+ Remove limitation that prevents from opening images bigger than 4 billion pixels
+
+ However the intermediate buffer for decoding must still be smaller than 4
+ billion pixels, so this is useful for decoding at a lower resolution level,

+ Sub-tile decoding: only allocate tile component buffer of the needed dimension
+
+ Instead of being the full tile size.
+
+ * Use a sparse array mechanism to store code-blocks and intermediate stages of
+ IDWT.
+ * IDWT, DC level shift and MCT stages are done just on that smaller array.
+ * Improve copy of tile component array to final image, by saving an intermediate
+ buffer.
+ * For full-tile decoding at reduced resolution, only allocate the tile buffer to
+ the reduced size, instead of the full-resolution size.
