Returns a new quantization table where the values are multiplied
by scaleFactor
and then clamped to the range 1..32767
(or to 1..255 if forceBaseline
is true).
Values of scaleFactor
less than 1 tend to improve
the quality level of the table, and values greater than 1.0
degrade the quality level of the table.
scaleFactor | multiplication factor for the table. | |
forceBaseline | if true ,
the values will be clamped to the range 1..255 |
