+Description: GDCM does not read Spacing properly.
+Date: 2006 June 5
+Attributed:
+Details:
+GDCM is ready completely random values to find out the spacing/origin or an
+image. It *SHOULD* first find the IOD and then deduce which tags to read
+Eg: Cross section this is in Pixel Spacing (0028,0030)
+CR is in Imager Pixel Spacing (0018,1164)
+US is in Pixel Ratio (0028,0034)
+RT is in :
+(3002,0011) Image Plane Pixel Spacing
+(3002,0012) RT Imaga ePosition
+and
+(3004,000c) for deducing Z spacing

+Details:
+ Doing a PrintFile on RickAvila DataSet we get:

+Whereas hexedit shows 3030 ??

+Date: 2005 Sep 14

+Details:
+ As reported in ITK mailing list, the global symbols are completely
+ skrewed up in gdcm, preventing one to dlopen/dlclose gdcm lib.

+Description: Add testing of valid dictionary
+Date: 2005 Aug 31
+Attributed: Mathieu
+Details:
+Since that now private/shadow dictionary are available
+it would be nice to start implementing an automatic mode of loading
+those dictionary as we read the public one.
+Comments: It shouldn't be too difficult to 'manualy' ask memory merging
+ of a Private Dict into the public one (I can do it soon).
+ Automatic recognition of the Private Dict to be used seems hopeless.

+Description: gdcm::SerieHelper / UID / set of rules
+Date: 2005 Aug 30
+Attributed: Mathieu
+Details:
+ gdcm::SerieHelper now offer a mechanism to add rules to sub select image
+as we iterate over them within a subdirectory structure. But what if UID was too
+restrictive ? Therefore UID subselection become only a good default rule, which
+should ideally be removed when user need a specific task.

the corresponding DicomDirPatient, etc. using the content of the SQItem
(the content is composed with some DocEntry's that can't be destroyed).
So, if the SQItem is deleted, then it's content is deleted to. But the

be deleted, and when have memory leaks

Description: [BUG] Better handling of unfound Dicom dictionary.
When gdcm doesn't find the Dicom dictionary (because it's
possible any how). This plane normal could be extracted from
the "orientation" info of the gdcmHeader ( refer to
grep "Orientation" Dicts/dicomV3.dic).
- Problem exhibiting this defect: cine loop on a pile of images

whose Origin is correct, but whose normal is not set will
plainly suck !

Dicom file ? Any examples on-line ?
+ * jpr : some are in gdcm/Dicts (built from pdf documents found on constructors'

* vtk/vtkGdcmHeader.cxx: if speed becomes a concern some changes can
be made at the cost of memory consumption (refer to header of

gdcmElValSet::SetElValueLengthByNumber) is used nowhere...
