NAME

6       dcmdjpls - Decode JPEG-LS compressed DICOM file
7

SYNOPSIS

10       dcmdjpls [options] dcmfile-in dcmfile-out
11

DESCRIPTION

13       The  dcmdjpls  utility reads a JPEG-ls compressed DICOM image (dcmfile-
14       in), decompresses the JPEG-LS data (i. e. conversion to a native  DICOM
15       transfer  syntax)  and  writes  the  converted  image to an output file
16       (dcmfile-out).
17

58
59         -f   --read-dataset
60                read data set without file meta information
61
62         # This option allows one to decompress JPEG-LS compressed DICOM objects that have
63         # been stored as dataset without meta-header. Such a thing should not exist
64         # since the transfer syntax cannot be reliably determined without meta-header,
65         # but unfortunately it does.
66
67   processing options
68       planar configuration:
69
70         +pr  --planar-restore
71                restore original planar configuration (default)

LOGGING

201       The level of logging output of  the  various  command  line  tools  and
202       underlying  libraries  can  be  specified by the user. By default, only
203       errors and warnings are written to the  standard  error  stream.  Using
204       option  --verbose  also  informational messages like processing details
205       are reported. Option --debug can be used to get  more  details  on  the
206       internal  activity,  e.g.  for debugging purposes. Other logging levels
207       can be selected using option --log-level. In --quiet  mode  only  fatal
208       errors  are reported. In such very severe error events, the application
209       will usually terminate. For  more  details  on  the  different  logging
210       levels, see documentation of module 'oflog'.
211
212       In  case  the logging output should be written to file (optionally with
213       logfile rotation), to syslog (Unix) or the event log  (Windows)  option
214       --log-config  can  be  used.  This  configuration  file also allows for
215       directing only certain messages to a particular output stream  and  for
216       filtering  certain  messages  based  on the module or application where
217       they are generated.  An  example  configuration  file  is  provided  in
218       <etcdir>/logger.cfg.
219

COMMAND LINE

221       All  command  line  tools  use  the  following notation for parameters:
222       square brackets enclose optional  values  (0-1),  three  trailing  dots
223       indicate  that multiple values are allowed (1-n), a combination of both
224       means 0 to n values.
225
226       Command line options are distinguished from parameters by a leading '+'
227       or  '-' sign, respectively. Usually, order and position of command line
228       options are arbitrary (i.e. they  can  appear  anywhere).  However,  if
229       options  are  mutually exclusive the rightmost appearance is used. This
230       behavior conforms to the  standard  evaluation  rules  of  common  Unix
231       shells.
232
233       In  addition,  one  or more command files can be specified using an '@'
234       sign as a prefix to the filename (e.g. @command.txt).  Such  a  command
235       argument  is  replaced  by  the  content of the corresponding text file
236       (multiple whitespaces are treated as a  single  separator  unless  they
237       appear  between  two  quotation marks) prior to any further evaluation.
238       Please note that a command file cannot contain  another  command  file.
239       This  simple  but  effective  approach  allows  one to summarize common
240       combinations of options/parameters and  avoids  longish  and  confusing
241       command lines (an example is provided in file <datadir>/dumppat.txt).
242

ENVIRONMENT

244       The  dcmdjpls  utility  will  attempt  to  load DICOM data dictionaries
245       specified in the DCMDICTPATH environment variable. By default, i.e.  if
246       the   DCMDICTPATH   environment   variable   is   not   set,  the  file
247       <datadir>/dicom.dic will be loaded unless the dictionary is built  into
248       the application (default for Windows).
249
250       The   default   behavior   should  be  preferred  and  the  DCMDICTPATH
251       environment variable only used when alternative data  dictionaries  are
252       required.  The  DCMDICTPATH environment variable has the same format as
253       the Unix shell PATH variable in that a colon (':')  separates  entries.
254       On  Windows systems, a semicolon (';') is used as a separator. The data
255       dictionary code will  attempt  to  load  each  file  specified  in  the
256       DCMDICTPATH  environment variable. It is an error if no data dictionary
257       can be loaded.
