149 libjpeg-turbo supports IDCT scaling with scaling factors of 1/8, 1/4, 3/8,

187 - **libjpeg API: DCT scaling in compressor**<br>
189 There is no technical reason why DCT scaling could not be supported when
191 below), only scaling factors of 1/2, 8/15, 4/7, 8/13, 2/3, 8/11, 4/5, and
205 additional DCT scaling factors.
209 This requires the DCT scaling feature, which is not supported.
212 This requires both the DCT scaling and SmartScale features, which are not
