kdu_codestream::get_tile_dims

Same as get_dims except that it returns the location and dimensions of only a single tile (if comp_idx is negative) or tile-component (if comp_idx >= 0). The tile indices must lie within the range identified by the get_valid_tiles function. As with get_dims, all coordinates and dimensions are affected by the prevailing geometric appearance and constraints set up using the change_appearance and apply_input_restrictions functions. As a result, the function returns the same dimensions as those returned by the kdu_tile_comp::get_dims function provided by the relevant tile-component; however, the present function has the advantage that it can be used without first opening the tile — an act which may consume substantial internal resources and may involve substantial parsing of the code-stream.
