Public Methods

Method	Description
jpeg_d_post_controller ( jpeg_decompress_struct cinfo, bool need_full_buffer )	Initialize postprocessing controller.
post_process_data ( ComponentBuffer input_buf, int &in_row_group_ctr, int in_row_groups_avail, byte output_buf, int &out_row_ctr, int out_rows_avail ) : void
start_pass ( J_BUF_MODE pass_mode ) : void	Initialize for a processing pass.

Private Methods

Method	Description
post_process_1pass ( ComponentBuffer input_buf, int &in_row_group_ctr, int in_row_groups_avail, byte output_buf, int &out_row_ctr, int out_rows_avail ) : void	Process some data in the one-pass (strip buffer) case. This is used for color precision reduction as well as one-pass quantization.
post_process_2pass ( byte output_buf, int &out_row_ctr, int out_rows_avail ) : void	Process some data in the second pass of 2-pass quantization.
post_process_prepass ( ComponentBuffer input_buf, int &in_row_group_ctr, int in_row_groups_avail, int &out_row_ctr ) : void	Process some data in the first pass of 2-pass quantization.
