- _d_i_t_h_e_r_s_t_i_f_f dithers the images contained in a stream TIFF (STIFF) file
- using a modified Floyd and Steinberg error diffusion dithering algorithm.
- The input images should have 8 bits per color component. The output
- images will be dithered to 1 bit per color component.
-
- _d_i_t_h_e_r_s_t_i_f_f supports the following colorspace models: kkkk, wwww, ccccmmmmyyyy, ccccmmmmyyyykkkk,
- yyyymmmmcccc, yyyymmmmcccckkkk, kkkkccccmmmmyyyy and rrrrggggbbbb. PPPPllllaaaannnnaaaarrrr and cccchhhhuuuunnnnkkkkyyyy raster formats are supported.
- The colorspace and raster format remained unchanged in the output stream.

- _d_i_t_h_e_r_s_t_i_f_f supports the following command line options:
-
- ----IIII _f_i_l_e_n_a_m_e
- Specifies the name of the file from which the STIFF input will
- be read. If the ----IIII option is not specified, input will be read
- from the standard input.
-
- ----OOOO _f_i_l_e_n_a_m_e
- Specifies the name of the file to which the STIFF output will
- be sent. If the ----OOOO option is not specified, output will be
- sent to the standard output.
-
- ----LLLL _f_i_l_e_n_a_m_e
- Specifies the name of the file to which error, warning and
- informational messages are to be written. If the file specified
- already exists, any messages generated by _d_i_t_h_e_r_s_t_i_f_f will be
- appended to the end of the file. If the ----LLLL option is not
- specified, message output will be sent to standard error.
-
- ----eeee Use a classic Floyd and Steinberg dither (error diffusion).
-
- ----ssss Use a modified Floyd and Steinberg error diffusion dither (a
- two weight error filter with random perturbations is used to
- reduce visual artifacts). This is the default.
-
- ----hhhh Prints a program usage message to the standard error.
-
- ----DDDD Specifies verbose output for debugging purposes.
-
- NNNNOOOOTTTTEEEESSSS
- _d_i_t_h_e_r_s_t_i_f_f is typically used as a filter between _p_s_r_i_p and a printer
- driver to provide error diffusion dithered images for the printer.
