I have just been experimenting with this option on my Windows computer, running IM 7.0.8-23 Q16 x64:
Code: Select all
magick -size 256x256 -depth 8 -seed 1000 plasma:fractal -define jpeg:q-table="C:\Temp\Erich\table.xml" plasma_my.jpg
checking the DQT afterwards with JPEGsnoop (https://www.impulseadventure.com/photo/jpeg-snoop.html
) and additionally with a hexeditor.
The DQT entries are not identical to those provided in the XML-File; there seems to be some sort of scaling going on. Same result for the XML-File provided with IM 7, i.e. quantization-table.xml.
Am I missing some point?

I'm having the same problem. Any luck?
