To despeckle existing MG3, MG4 and JPEG 2000 images without reencoding:
Use the ‑despeckleonly
switch. For example:
mrsidgeoencoder -i foo.sid -o foo2.sid ‑despeckleonly
If you use this switch, you cannot specify any other encoding options except for tile length markers (‑tlm
/ ‑tilelengthmarkers
; specify zero to disable), packet length markers (‑plt
/ ‑packetlengthmarkers
or ‑noplt
/ ‑nopltmarkers
), and tile parts (‑tp
/ ‑tileparts
; specify N to disable). For more information see JPEG 2000 Encoding.
