$ cjpeg -progressive -arithmetic -rgb -block 1 -outfile huge1.jpg -quality 100 huge.ppm
Just noticed another point: The "-quality 100" here. This adds to the size of the compressed file but with no benefit here. The default quality setting (75) is already lossless for block size 1 (due to DCT property and as described in man page). Perhaps such setting could be used to achieve higher sample precision processing, this can be investigated. Ciao Guido -- To UNSUBSCRIBE, email to [email protected] with a subject of "unsubscribe".
