man dcmcrle (Commandes) - Encode DICOM file to RLE transfer syntax
NAME
dcmcrle - Encode DICOM file to RLE transfer syntax
SYNOPSIS
dcmcrle [options] dcmfile-in dcmfile-out
DESCRIPTION
The dcmcrle utility reads an uncompressed DICOM image (dicomfile-in), performs RLE compression (i.e. conversion to an encapsulated DICOM transfer syntax) and writes the converted image to an output file (dicomfile-out).
PARAMETERS
dcmfile-in DICOM input filename to be converted
dcmfile-out DICOM output filename
OPTIONS
general options
-h --help print this help text and exit
--version print version information and exit
-v --verbose verbose mode, print processing details
-d --debug debug mode, print debug information
input options
input file format:
+f --read-file read file format or data set (default)
+fo --read-file-only read file format only
-f --read-dataset read data set without file meta information
input transfer syntax:
-t= --read-xfer-auto use TS recognition (default)
-td --read-xfer-detect ignore TS specified in the file meta header
-te --read-xfer-little read with explicit VR little endian TS
-tb --read-xfer-big read with explicit VR big endian TS
-ti --read-xfer-implicit read with implicit VR little endian TS
encapsulated pixel data encoding options
pixel data fragmentation options:
+ff --fragment-per-frame encode each frame as one fragment (default)
+fs --fragment-size [s]ize: integer limit fragment size to s kbytes (non-standard)
basic offset table encoding options:
+ot --offset-table-create create offset table (default)
-ot --offset-table-empty leave offset table empty
SOP Class UID options:
+cd --class-default keep SOP Class UID (default)
+cs --class-sc convert to Secondary Capture Image (implies --uid-always)
SOP Instance UID options: +un --uid-never never assign new UID (default)
+ua --uid-always always assign new UID
output options
post-1993 value representations:
+u --enable-new-vr enable support for new VRs (UN/UT) (default)
-u --disable-new-vr disable support for new VRs, convert to OB
group length encoding:
+g= --group-length-recalc recalculate group lengths if present (default)
+g --group-length-create always write with group length elements
-g --group-length-remove always write without group length elements
length encoding in sequences and items:
+e --length-explicit write with explicit lengths (default)
-e --length-undefined write with undefined lengths
data set trailing padding:
-p= --padding-retain do not change padding (default)
-p --padding-off no padding
+p --padding-create [f]ile-pad [i]tem-pad: integer align file on multiple of f bytes and items on multiple of i bytes
COMMAND LINE
All command line tools use the following notation for parameters: square brackets enclose optional values (0-1), three trailing dots indicate that multiple values are allowed (1-n), a combination of both means 0 to n values.
Command line options are distinguished from parameters by a leading '+' or '-' sign, respectively. Usually, order and position of command line options are arbitrary (i.e. they can appear anywhere). However, if options are mutually exclusive the rightmost appearance is used. This behaviour conforms to the standard evaluation rules of common Unix shells.
In addition, one or more command files can be specified using an '@' sign as a prefix to the filename (e.g. @command.txt). Such a command argument is replaced by the content of the corresponding text file (multiple whitespaces are treated as a single separator) prior to any further evaluation. Please note that a command file cannot contain another command file. This simple but effective approach allows to summarize common combinations of options/parameters and avoids longish and confusing command lines (an example is provided in file share/data/dumppat.txt).
ENVIRONMENT
The dcmcrle utility will attempt to load DICOM data dictionaries specified in the DCMDICTPATH environment variable. By default, i.e. if the DCMDICTPATH environment variable is not set, the file <PREFIX>/lib/dicom.dic will be loaded unless the dictionary is built into the application (default for Windows).
The default behaviour should be preferred and the DCMDICTPATH environment variable only used when alternative data dictionaries are required. The DCMDICTPATH environment variable has the same format as the Unix shell PATH variable in that a colon (':') separates entries. The data dictionary code will attempt to load each file specified in the DCMDICTPATH environment variable. It is an error if no data dictionary can be loaded.
