ANNOUNCEMENT
Version 3.5.2 of the OFFIS DCMTK (DICOM ToolKit) software is now available
for public release. This release includes the following main changes
over the previous version (Version 3.5.1):
- Better ISO C++ compliance. If available, the standard header
files such as <iostream> and <cmath> are used instead of the
traditional <iostream.h> and <math.h> headers.
Visual C++ users are strongly advised to read the platform
notes in the INSTALL file concerning iostream issues.
- DCMTK 3.5.2 builds correctly with GCC 3.2 and Visual C++ .NET
- Various enhancements in the configure system which now works
correctly without manual interaction on more platforms: Irix,
HP/UX 10 and MacOS X 10.2 now build "out of the box".
- Support for encoding/decoding RLE compressed DICOM images has been
added. The new tools dcmcrle and dcmdrle allow to convert between
uncompressed and RLE compressed transfer syntaxes.
- Support for zlib compressed (deflated) DICOM objects has been added.
Conversion between uncompressed and deflated transfer syntaxes
is offered by dcmconv.
- The new application dcmscale allows to scale DICOM images.
- The new application dcm2xml converts DICOM objects to XML.
- The new application dcmquant converts any DICOM color image into
a palette color image. The underlying quantization classes are useful
for creating palette color icons from color images.
- The Worklist CTN has been replaced by a completely new implementation
(module dcmwlm) that supports a larger set of keys, fixes various
issues with the old implementation and has a well-defined backend that
facilitates adaptation to databases etc.
- Most command line tools now support a command line option "--version"
which prints the host platform and the name and version number of
external libraries.
- Echoscu now supports C-ECHO over TLS (Security Enhancements One).
- Added support for new value representation Other Float String (OF).
- New layout for dcmdump tool, improves readability.
- Conversion between floating point numbers and ASCII strings (e.g. in
DICOM DS data elements) is now performed in a locale independent manner,
making sure that DCMTK works correctly in a non-Posix locale.
- Complete re-design of the DICOM I/O stream classes, required for
zlib support. Critical API change. Programmers are advised to adapt
their applications to the new DcmFileFormat loadFile() and saveFile()
methods which encapsulate the new stream architecture.
- Support for private tag data dictionaries has been added. This can be
activated in configure using the --with-private-tags option. By default,
no private tag dictionary is installed.
- Unknown undefined length attributes are now converted into SQ instead of UN.
- Improved behaviour when reading elements with illegal odd tag length.
- Many network tools now have a command line option --timeout for
controlling the connection request timeout.
- A-ASSOCIATE user information sub items are now always sent in ascending
order to avoid problems with certain other DICOM toolkits.
- Added experimental "promiscuous" mode to storescp. In this mode,
activated by the --promiscuous command line option, all presentation
contexts not known not to be Storage SOP Classes are accepted.
- Added --max-send-pdu option to storescu that allows to
restrict the size of outgoing P-DATA PDUs.
- Added support for the Numeric Value Qualifier Code Sequence
(introduced with CP 260) to dcmsr module.
- Added support for the Current Requested Procedure Evidence Sequence
and the Pertinent Other Evidence Sequence to the dcmsr module.
- Dcmmkdir tool supports more application profiles.
- Algorithm for creation of unique identifiers has been improved on
Win32 platforms where gethostid() is not available.
- The DICOM data dictionary has been re-worked based on the latest
supplements and correction proposals, as usual.
- Many bug fixes and minor improvements as usual - See the CHANGES.352
file for more details.
