--use-meta-length use file meta information group length (default) -ml --ignore-meta-length ignore file meta information group length parsing of odd-length attributes: +ao --accept-odd-length accept odd length attributes (default) +ae --assume-even-length assume real length is one byte larger handling of explicit VR: +ev --use-explicit-vr use explicit VR from dataset (default) -ev --ignore-explicit-vr ignore explicit VR (prefer data dictionary) handling of non-standard VR: +vr --treat-as-unknown treat non-standard VR as unknown (default) -vr --assume-implicit try to read with implicit VR little endian TS handling of undefined length UN elements: +ui --enable-cp246 read undefined len UN as implicit VR (default) -ui --disable-cp246 read undefined len UN as explicit VR handling of defined length UN elements: -uc --retain-un retain elements as UN (default) +uc --convert-un convert to real VR if known handling of private max-length elements (implicit VR): -sq --maxlength-dict read as defined in dictionary (default) +sq --maxlength-seq read as sequence with undefined length handling of wrong delimitation items: -rd --use-delim-items use delimitation items from dataset (default) +rd --replace-wrong-delim replace wrong sequence/item delimitation items handling of illegal undefined length OB/OW elements: -oi --illegal-obow-rej reject dataset with illegal element (default) +oi --illegal-obow-conv convert undefined length OB/OW element to SQ handling of VOI LUT Sequence with OW VR and explicit length: -vi --illegal-voi-rej reject dataset with illegal VOI LUT (default) +vi --illegal-voi-conv convert illegal VOI LUT to SQ handling of explicit length pixel data for encaps. transfer syntaxes: -pe --abort-expl-pixdata abort on explicit length pixel data (default) +pe --use-expl-pixdata use explicit length pixel data general handling of parser errors: +Ep --ignore-parse-errors try to recover from parse errors -Ep --handle-parse-errors handle parse errors and stop parsing (default) other parsing options: +st --stop-after-elem [t]ag: "gggg,eeee" or dictionary name stop parsing after element specified by t +sb --stop-before-elem [t]ag: "gggg,eeee" or dictionary name stop parsing before element specified by t automatic data correction: +dc --enable-correction enable automatic data correction (default) -dc --disable-correction disable automatic data correction bitstream format of deflated input: +bd --bitstream-deflated expect deflated bitstream (default) +bz --bitstream-zlib expect deflated zlib bitstream processing options: specific character set: +U8 --convert-to-utf8 convert all element values that are affected by Specific Character Set (0008,0005) to UTF-8 output options: printing: +L --print-all print long tag values completely -L --print-short print long tag values shortened (default) +T --print-tree print hierarchical structure as a simple tree -T --print-indented print hierarchical structure indented (default) +F --print-filename print header with filename for each input file +Fs --print-file-search print header with filename only for those input files that contain one of the searched tags mapping: +Un --map-uid-names map well-known UID numbers to names (default) -Un --no-uid-names do not map well-known UID numbers to names quoting: +Qn --quote-nonascii quote non-ASCII and control chars as XML markup +Qo --quote-as-octal quote non-ASCII and control ch. as octal numbers -Qn --print-nonascii print non-ASCII and control chars (default) color: +C --print-color use ANSI escape codes for colored output -C --no-color do not use any ANSI escape codes (default) error handling: -E --stop-on-error do not print if file is damaged (default) +E --ignore-errors attempt to print even if file is damaged searching: +P --search [t]ag: "gggg,eeee" or dictionary name print the textual dump of tag t this option can be specified multiple times (default: the complete file is printed) +s --search-all print all instances of searched tags (default) -s --search-first only print first instance of searched tags +p --prepend prepend sequence hierarchy to printed tag, denoted by: (gggg,eeee).(gggg,eeee).* (only when used with --search) -p --no-prepend do not prepend hierarchy to tag (default) writing: +W --write-pixel [d]irectory: string write pixel data to a .raw file stored in d (little endian, filename created automatically)
