70 -quality N[,...] Scale quantization tables to adjust image quality.
118 -quality 100 will generate a quantization table of all 1's, minimizing loss
119 in the quantization step (but there is still information loss in subsampling,
129 quantization tables, which are considered optional in the JPEG standard.
136 provided quantization table slot). This feature is useful for high-quality
141 Note that the -quality ratings refer to the quantization table slots, and that
146 both luminance and chrominance (slots 0 and 1). More or custom quantization
200 quantization tables can be adjusted accordingly.
257 -baseline Force baseline-compatible quantization tables to be
258 generated. This clamps quantization values to 8 bits
264 -qtables file Use the quantization tables given in the specified
267 -qslots N[,...] Select which quantization table to use for each color
356 -dither fs Use Floyd-Steinberg dithering in color quantization.
357 -dither ordered Use ordered dithering in color quantization.
358 -dither none Do not use dithering in color quantization.
364 no effect unless color quantization is being done.
376 -onepass Use one-pass instead of two-pass color quantization.
438 Two-pass color quantization requires a good deal of memory; on MS-DOS machines
441 one-pass quantization.
