16 (pronounced "jay-peg") is a standardized compression method for full-color
143 -dct int Use integer DCT method (default).
145 -dct float Use floating-point DCT method.
146 The float method is very slightly more accurate than
147 the int method, but is much slower unless your machine
149 results of the floating-point method may vary slightly
151 the same results everywhere. The fast integer method
266 -dct int Use integer DCT method (default).
268 -dct float Use floating-point DCT method.
269 The float method is very slightly more accurate than
270 the int method, but is much slower unless your machine
272 results of the floating-point method may vary slightly
274 the same results everywhere. The fast integer method
298 The one-pass method is faster and needs less memory,
301 the one-pass method is always used for gray-scale
302 output (the two-pass method is no improvement then).
473 luminance channel is preserved exactly, so this is a better method of reducing
