C# 클래스 BitMiracle.LibJpeg.Classic.Internal.my_trans_c_coef_controller

This is a special implementation of the coefficient buffer controller. This is similar to jccoefct.c, but it handles only output from presupplied virtual arrays. Furthermore, we generate any dummy padding blocks on-the-fly rather than expecting them to be present in the arrays.

메소드 설명
compress_data ( byte input_buf ) : bool

Process some data. We process the equivalent of one fully interleaved MCU row ("iMCU" row) per call, ie, v_samp_factor block rows for each component in the scan. The data is obtained from the virtual arrays and fed to the entropy coder. Returns true if the iMCU row is completed, false if suspended. NB: input_buf is ignored; it is likely to be a null pointer.
my_trans_c_coef_controller ( jpeg_compress_struct cinfo, jvirt_array coef_arrays )

Initialize coefficient buffer controller. Each passed coefficient array must be the right size for that coefficient: width_in_blocks wide and height_in_blocks high, with unit height at least v_samp_factor.
start_pass ( J_BUF_MODE pass_mode ) : void

Initialize for a processing pass.
