Enum J_DCT_METHOD
Algorithm used for the DCT step.
Namespace: BitMiracle.LibJpeg.Classic
Assembly: BitMiracle.LibJpeg.NET.dll
Syntax
public enum J_DCT_METHODRemarks
The FLOAT method is very slightly more accurate than the ISLOW method,
but may give different results on different machines due to varying roundoff behavior.
The integer methods should give the same results on all machines. On machines with
sufficiently fast hardware, the floating-point method may also be the fastest.
The IFAST method is considerably less accurate than the other two; its use is not recommended
if high quality is a concern.
