72         -quality N[,...]  Scale quantization tables to adjust image quality.
112 -quality 100 will generate a quantization table of all 1's, minimizing loss
113 in the quantization step (but there is still information loss in subsampling,
123 quantization tables, which are considered optional in the JPEG standard.
130 separate settings for every quantization table slot.)  The principle is the
142 quantization table slots.  If there are more q-table slots than parameters,
146 customized) quantization tables can be set with the -qtables option and
235         -baseline       Force baseline-compatible quantization tables to be
236                         generated.  This clamps quantization values to 8 bits
242         -qtables file   Use the quantization tables given in the specified
245         -qslots N[,...] Select which quantization table to use for each color
346         -dither fs      Use Floyd-Steinberg dithering in color quantization.
347         -dither ordered Use ordered dithering in color quantization.
348         -dither none    Do not use dithering in color quantization.
354                         no effect unless color quantization is being done.
366         -onepass        Use one-pass instead of two-pass color quantization.
423 Two-pass color quantization requires a good deal of memory; on MS-DOS machines
426 one-pass quantization.
