.PP
\fB\-n\fR           : number of resolutions (\fB\-n\fR 3,3,3)

.PP
\fB\-r\fR           : different compression ratios for successive layers (\fB\-r\fR 20,10,5)
.IP
The rate specified for each quality level is the desired compression factor, rate 1 means
lossless compression (options \fB\-r\fR and \fB\-q\fR cannot be used together).
.PP
\fB\-q\fR           : different psnr for successive layers (\fB\-q\fR 30,40,50)
.IP
(options \fB\-r\fR and \fB\-q\fR cannot be used together)
.PP
\fB\-b\fR           : size of code block (\fB\-b\fR 32,32,32)
.PP

.PP
\fB\-t\fR           : size of tile (\fB\-t\fR 512,512,512)
.PP
\fB\-p\fR           : progression order (\fB\-p\fR LRCP) [LRCP, RLCP, RPCL, PCRL, CPRL]
.PP
\fB\-s\fR           : subsampling factor (\fB\-s\fR 2,2,2) [\-s X,Y,Z]
.IP
Note: subsampling bigger than 2 can produce error.
.PP
\fB\-SOP\fR         : write SOP marker before each packet
.PP
\fB\-EPH\fR         : write EPH marker after each header packet
.PP
\fB\-M\fR           : code\-block style (\fB\-M\fR 0)
.IP
[1=BYPASS(LAZY) 2=RESET 4=RESTART(TERMALL) 8=VSC 16=PTERM 32=SEGSYM 64=3DCTXT]
.IP
Indicate multiple modes by adding their values, for example: RESTART(4) + RESET(2) + SEGMARK(32) = \fB\-M\fR 38
.PP
\fB\-D\fR           : define DC offset (\fB\-D\fR 12)
.PP
\fB\-x\fR           : create an index file *.Idx (\fB\-x\fR index_name.Idx)
.PP
\fB\-ROI\fR         : c=%d,U=%d
.IP
Quantization indices upshifted for component c=%d [%d = 0,1,2]
with a value of U=%d [0 <= %d <= 37] (i.e. \fB\-ROI\fR:c=0,U=25)
.PP
\fB\-d\fR           : offset of the origin of the volume (\fB\-d\fR 150,300,100)
.PP
\fB\-l\fR           : offset of the origin of the tiles (\fB\-l\fR 100,75,25)
.SS

.PP
- No mode switch activated
.PP
- Progression order: LRCP
.PP
- No index file
.PP
- No ROI upshifted
.PP
- No offset of the origin of the volume
.PP
- No offset of the origin of the tiles
.PP

.SS
Remarks:
.PP
The markers written to the main_header are : SOC SIZ COD QCD COM.
.PP
COD and QCD markers will never appear in the tile_header.
.PP
You need enough disk space memory (twice the original) to encode the volume,
i.e. for a 1.5 GB volume you need a minimum of 3GB of disk memory)
.PP
When loading *.pgx files, a relative path to directory is needed for input argument
followed by the common prefix of the slices and a '*' character representing sequential numeration
( \fB\-i\fR relativepath/slices*.pgx ).
.PP
The index file has the structure below:
.IP
Image_height Image_width Image_depth
.IP
Progression order: 0 (LRCP)
.IP
Tiles_size_X Tiles_size_Y Tiles_size_Z
