(LOw COmplexity LOssless COmpression for Images)
developed at Hewlett-Packard Laboratories]
</UL>
- <LI> gdcm doesn't read yet all <TT>JPEG2000</TT> encoded files.
- <UL>
- But we are working on it (a lot of troubles with Jasper).
- Update: as of Oct 10 2005, we are currently investigating another library:
- openjpeg. The problem still exist for this library but one of the author
- is currently working on it:
- http://www.openjpeg.org/forum/viewtopic.php?t=18
- </UL>
<LI> gdcm doesn't read yet <TT>MPEG2</TT> encoded files.
</UL>
<TT>SeqEntry</TT> (if any)
<LI> Allow user to tell the Writer he doesn't want to write down
<TT>Shadow groups</TT> (if any)
- <LI> Allow user to tell the Writer which compression mode he wants<br>
- (Right now, no one is available)
<LI> Allow user to tell the Writer he wants to split a
<TT>Multiframe</TT> image into a serie of
<TT>Single frame</TT> images.
<UL>
<LI> 16-bits-LUT full Management
<LI> User friendly management of <TT>Rescale Slope</TT> and
- <TT>Rescale Intercept</TT>
+ <TT>Rescale Intercept</TT>.<br>
+ (Well... Maybe it's up to the application to deal with it, not to
+ gdcm ?)
<LI> Allow manual adjunction / automatic recognition (pfff!...)
of the private <TT>Dicom Dictionary</TT>
to be used to parse <TT>Shadow groups</TT> against.
<LI> User friendly way of anonymizing image when Patient's name is
- carved in the Pixels :-(

<LI> New Features
+
<UL>
+ <LI> To be able to use gdcm1.3.x and ITK, developer is now allowed to
+ choose his own namespace for gdcm at CMake time : see GDCM_NAME_SPACE
+ option.
+ <LI> JPEG and JPEG2000 compression writting are now available.
+ see Examples/WriteDicomAsJPEG.cxx and Examples/WriteDicomAsJPEG2000.cxx
+ <LI> To <i>try to</i> make gdcm images PACS usable, user is now allowed to
+ gdcm what kind of image he wants to write, using : <br>
+ <TT>void FileHelper::SetContentType (ImageContentType c);</TT> <br>
+ Four different types are identify (probabely more will be added) :
+ <UL>
+ <LI>
+ 1) user created ex nihilo his own image and wants to write it as a Dicom image.<br>
+ c : <TT>USER_OWN_IMAGE</TT>
+ <LI>
+ 2) user modified the pixels of an existing image, using mathematical operations.<br>
+ c : <TT>FILTERED_IMAGE</TT>
+ <LI>
+ 3) user created a new image, using existing images (eg MIP, MPR, cartography image)<br>
+ c : <TT>CREATED_IMAGE</TT>
+ <LI>
+ 4) user modified/added some tags *without processing* the pixels (anonymization, etc)<br>
+ c : <TT>UNMODIFIED_PIXELS_IMAGE</TT>
+ </UL>
<LI> Stupid difference between <TT>gdcm::ValEntry</TT>
and <TT>gdcm::BinEntry</TT> removed. <br>
Only <TT>gdcm::DataEntry</TT> exist, now.
Should have been considered as a 'Bug Fix'.<br>
Actually, it's an API breaking modification ...
+ <UL>
+ <LI>
+ <TT>std::string const &DataEntry::GetString() const</TT><br>
+ returns as a string (when possible) the value of the DataEntry
+ <LI>
+ <TT>void DataEntry::SetString(std::string const &value)</TT><br>
+ Sets the 'value' of a DataEntry, passed as a std::string
+ <LI>
+ <TT>void DataEntry::SetBinArea( uint8_t *area, bool self ) </TT><br>
+ Sets the value (non string) of the current Dicom DataEntry
+ <LI>
+ <TT>void DataEntry::CopyBinArea( uint8_t *area, uint32_t length )</TT><br>
+ Inserts the value (non string) into the current DataEntry
+ <LI>
+ <TT>void DataEntry::SetValue(const uint32_t &id, const double
+ &val)</TT><br>
+ Inserts the elementary (non string) value into the current
+ (multivaluated) DataEntry, at the <TT>id></TT> position.
+ <LI>
+ <TT>double DataEntry::GetValue(const uint32_t &id) const </TT><br>
+ returns, as a double one of the values (when entry is
+ multivaluated), identified by its index <TT>id</TT>.
+ </UL>
+ <LI>
+ <TT>DocEntrySet::GetEntryValue()</TT> replaced by
+ <TT>DocEntrySet::GetEntryString()</TT> <br>
<LI> SerieHelper : <br>
Add some methods, to split a 'SingleSerieUID' Fileset into
'Extra Coherent' FileSets. <br>
of gdcm::File*)<br>
The key is the 'Orientation', the 'Position'
or the value of a user choosen 'Tag' <br>
- - XCoherentFileSetmap SplitOnOrientation(FileList *fileSet); <br>
- - XCoherentFileSetmap SplitOnPosition(FileList *fileSet); <br>
- - XCoherentFileSetmap SplitOnTagValue(FileList *fileSet,
- uint16_t group, uint16_t element); <br>
+ - <TT>XCoherentFileSetmap SplitOnOrientation(FileList *fileSet);
+ </TT><br>
+ - <TT>XCoherentFileSetmap SplitOnPosition(FileList *fileSet);
+ </TT> <br>
+ - <TT>XCoherentFileSetmap SplitOnTagValue(FileList *fileSet,
+ uint16_t group, uint16_t element);
+ </TT><br>
These methods must be called by user, depending on what he wants
to do, at application time.- *he* only knows what his Series
contain !-
- <LI>
+ <LI> To avoid memory leaks and seg faults the user intended classes
+ use now a Reference Counter.<br>
+ <UL>
+ <LI> <TT>new()</TT> and <TT>delete()</TT> are replaced by
+ <TT>New()</TT> and <TT>Delete()</TT>
+ <LI> <TT>Register()</TT> and <TT>Unregister()</TT> methods are
+ available.
+ <LI> --> Well ... People from ITK don't seem to agree too much with
+ that feature.<br>
+ They demand to be allowed to allocate gdcm objects in the stack as
+ well, not only in the heap.
