73         -quality N[,...]  Scale quantization tables to adjust image quality.
113 -quality 100 will generate a quantization table of all 1's, minimizing loss
114 in the quantization step (but there is still information loss in subsampling,
124 quantization tables, which are considered optional in the JPEG standard.
131 separate settings for every quantization table slot.)  The principle is the
143 quantization table slots.  If there are more q-table slots than parameters,
147 customized) quantization tables can be set with the -qtables option and
236         -baseline       Force baseline-compatible quantization tables to be
237                         generated.  This clamps quantization values to 8 bits
243         -qtables file   Use the quantization tables given in the specified
246         -qslots N[,...] Select which quantization table to use for each color
349         -dither fs      Use Floyd-Steinberg dithering in color quantization.
350         -dither ordered Use ordered dithering in color quantization.
351         -dither none    Do not use dithering in color quantization.
357                         no effect unless color quantization is being done.
369         -onepass        Use one-pass instead of two-pass color quantization.
