kdu_tile_comp::access_resolution

Returns an interface to the highest resolution level of the tile-component, within the internal code-stream management machinery. It is equivalent to calling the first form of the overloaded access_resolution function, supplying a res_level index equal to the value returned by get_num_resolutions.

You can then use kdu_resolution::access_next to access successively lower resolution levels within the same tile-component.

If the number of discarded resolution levels supplied in any call to kdu_codestream::apply_input_restrictions is larger than the number of DWT levels used to compress this tile-component, any call to the present function will generate an error through kdu_error. You can avoid this by checking the value returned by get_num_resolutions (it will be 0 if there is a problem) or by checking the value returned by kdu_codestream::get_min_dwt_levels.
