+ - gdcm doesn't read yet JPEG-LS encoded files.
+
+ We said 'JPEG-LS', not Lossless Jpeg ...
+ [JPEG-LS is the basis for new lossless/near-lossless compression
+ standard for continuous-tone images intended for JPEG2000.
+ The standard is based on the LOCO-I algorithm
+ (LOw COmplexity LOssless COmpression for Images)
+ developed at Hewlett-Packard Laboratories]
+
+ - gdcm doesn't read yet JPEG2000 encoded files.
+
+ But we are working on it.
+
+ - gdcm doesn't read yet MPEG2 encoded files.
+
+ But we are working on it.
+
+
+ - Reader
+
+ - Allow user to tell gdcm::Document constructor he just wants
+ to load a given list of DocEntries
+ (to save CPU time and RAM space)
+
- Allow 'frame by frame' reading (should be helpfull for huge
+ multiframe images)
+
- Allow subvolume selection / frames selection before reading.
+
- Expose Read/Decompression mechanisms to allow user getting
+ information from DICOMDIR
-or from his own Data Base-
+ and reading his images without parsing
+ the header, one more time.
+
+ - Writer
+
+ - Allow user to tell the Writer he doesn't want to write down
+ SeqEntry (if any)
+
- Allow user to tell the Writer he doesn't want to write down
+ Shadow groups (if any)
+
- Allow user to tell the Writer which compression mode he wants
+ (Right now, no one is available)
+ - Allow user to tell the Writer he wants to split a
+ Multiframe image into a serie of
+ Single frame images.
+
- Allow user to tell the Writer he wants to agregate a
+ Serie of Single frame images into a
+ Multiframe image.
+
+ - Reader / Writer
+
+ - Full Icon Image management (Read and Write)
+
- Full Overlays management (Read and Write)
+ both for 'ACR-NEMA style' (using groups 0x6000
+ and nexts) and 'DICOM V3 style' (using Sequences)
+
+ - DICOMDIR
+
+ - DICOMDIR full management (not limited to
+ PATIENT/STUDY/SERIE/IMAGE)
+
- Allow user to add an entry (belonging to the file header Dicom
+ entries)to the default entry list, before
+ making a DICOMDIR from a root directory
+
- Allow user to add an entry of his owns (for instance an Icon
+ to each image, or to each Serie).
+
+ - SerieHelper
+
+
+ - An accurate SerieHelper
+ Right now SerieHelper only works on 'bona fide Series', and
+ breaks on wrongly forged Series.
+ We are still looking for any heuristics...
+ - A SerieHelper that would use the DICOMDIR (if any)
+ instead of parsing all the files within the Root Directory
+
+ - Other
+
+ - 16-bits-LUT full Management
+
- User friendly management of Rescale Slope and
+ Rescale Intercept
+
- Allow parsing the Shadow groups against a user supplied
+ private Dicom Dictionary (pfff!...)

gdcm 0.6 UML Class Diagram version.
User Documentation"
Developper Documentation"
The new gdcmDocument class is a parent class of
gdcmHeader class and gdcmDicomDir class.
Massive modifications in the Class Diagram :
- - Entries (gdcmEntry) are now separated into
- ValEntry and SeqEntry (whose VR =
- SQ)
-
- a gdcmDocument is_a gdcmElementSet,
- composed of a set of gdcmValEntry
- and gdcmSeqEntry
-
- a gdcmSeqEntry is considered as a set
- of gdcmSQItem
-
- Dicom Sequences (VR = SQ) are now dealt as tree-like
- structures within gdcmSQItem class.
- they are considered as a set of gdcmSQItems
- - a gdcmSQItem is_a gdcmElementSet

- Improvement of the jpeg sub-library: jpeg
- compressed Dicom files (lossless and lossy)
