dcmcrle: Encode DICOM file to RLE transfer syntax
usage: dcmcrle [options] dcmfile-in dcmfile-out
parameters:
dcmfile-in DICOM input filename to be converted
("-" for stdin)
dcmfile-out DICOM output filename
("-" for stdout)
general options:
-h --help print this help text and exit
--version print version information and exit
--arguments print expanded command line arguments
-q --quiet quiet mode, print no warnings and errors
-v --verbose verbose mode, print processing details
-d --debug debug mode, print debug information
-ll --log-level [l]evel: string constant
(fatal, error, warn, info, debug, trace)
use level l for the logger
-lc --log-config [f]ilename: string
use config file f for the logger
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:
+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:
+ot --offset-table-create create offset table (default)
-ot --offset-table-empty leave offset table empty
icon image encoding:
+ic --icon-compressed compress icon images (default)
+iu --icon-uncompressed keep icon images uncompressed
SOP Class UID:
+cd --class-default keep SOP Class UID (default)
+cs --class-sc convert to Secondary Capture Image
(implies --uid-always)
SOP Instance UID:
+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
