(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.

<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.
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

<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.
<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.
