185 There is no technical reason why DCT scaling could not be supported when
192 SmartScale is an extension to the JPEG format that allows for DCT block
201 additional DCT scaling factors.
205 This requires the DCT scaling feature, which is not supported.
208 This requires both the DCT scaling and SmartScale features, which are not
274 v6b. The one exception to this is when using the floating point DCT/IDCT, in
278 - The SSE/SSE2 floating point DCT implementation in libjpeg-turbo is ever so
288 point DCT/IDCT algorithms are mainly a legacy feature, and they do not
296 floating point DCT/IDCT can depend on the compiler settings.

333 Fast Integer Forward DCT at High Quality Levels
337 correct results whenever the fast integer forward DCT is used along with a JPEG
340 It is therefore strongly advised that you use the slow integer forward DCT
