GDCM Release 2.0

From GDCM Wiki
Jump to: navigation, search

GDCM release 2.0 is a complete ground up rewrite of GDCM 1.x, it's initial goal was simply to provide the same functionalities as GDCM 1.x. GDCM 2.0.x has been superseeded by the 2.2.x branche GDCM Release 2.2.



what's new in GDCM 2.x that's not in GDCM 1.x ?

  • Basic structures are now exposed (Tag, DataElement, Item, Sequence)
  • Better support for DICOM in general (not image oriented anymore)
  • Support for private tags (double key lookup), ~8000 elements are supported
  • Can read/write an image without the need to decompress it first.
  • support for deflated stream !
  • gdcm::Scanner a super fast scanner, which scan a directory in search for particular tags
  • initial wrapping of library in java and C#
  • a threaded vtk reader (for advanced users only)
  • a readahead daemon on linux to cache image
  • a much better support for Enhanced CT/MR Image Storage (do not support intermixed volumes)
  • CSA Header support (SIEMENS)
  • Protocol Data Block support (GEMS)
  • Part 3 implementation, see the actual XML file
  • RLE encoder
  • Better J2K/JPEG2000 encoder/decoder
  • JPEG-LS encoder/decoder !
  • a gdcmanon tool !
  • ... and much more, have a look at the class list, or the list of supported files

what's missing from GDCM 1.x ?

  • LOAD_MODE disappear, its use was broken anyway:
    • some user assumed that LD_NOSHADOW meant that no private tag would be read, while it means only private group when group length is found would not be loaded
    • some user assumed that LD_NOSEQ/LD_NOSHADOWSEQ meant that no SQ would be read, while it means that only defined length SQ would not be read

As a more general solution a gdcm::Scanner class was implemented.

GDCM 2.0.0

First release on the GDCM 2.0 branch


GDCM 2.0.1

GDCM 2.0.0 will generate files that will be considered invalid with CP-882. Therefore users are urged to switch to GDCM 2.0.1 or svn trunk to solve that issue.


GDCM 2.0.2

  • A fairly large number of files have been modified (~3600 lines of unix diff -u3).
  • VTK 4.4 and VTK 5 compilation issue have been solved. VTK CVS (5.2 when it comes out) remains the prefered VTK release.
  • RLE image are now properly read again.
  • Curve Data are now properly loaded
  • Overlay Data are properly loaded and passed as Output #1 in VTK
  • Fix gdcm::Directory on Win32
  • PALETTE COLOR are now loaded as grayscale image with a gdcm::LookupTable attached. The old behavior of automatically applying the lut has been removed.
  • mpeg2, jpegls and expat directory have been remove from the utilities. They are currently not used in the implementation of gdcm 2.0


GDCM 2.0.3

  • Big Endian image, including the GE private SOP are now properly supported.
  • YBR_422_FULL in single component grayscale image is now properly handled
  • Better Python wrapping for the gdcm::Scanner
  • gdcm::Scanner support binary VR
  • The remaining troublesome Philips -buggy- images are now dynamically handle and rewritten correctly (dcmtk can read them back).
  • (0040,a125) public data element was added (not in PS 3.6 - 2008)
  • Better support for looking up a PrivateTag in a dataset
  • Better support for CSAHeader
  • Fast path for loading raw DICOM image file
  • gdcm::StringFilter Support for context dependant data element (Minor API change), those which depend on 0028,0103 (US or SS)
  • BUG: YBR and PlanarConfiguration are now properly handled (were merged previously)
  • More work on gdcm::Printer to try to print value contained in data field
  • Better detection of binary file (when code path was checking for old ACR file)
  • Fix bug when printing a gdcm::VM
  • Squeeze couple of bytes in gdcm::Fragment / gdcm::BasicOffsetTable
  • BUG: Fix incorrect representation for VR::UT
  • NEW: Addition of a ImageFormat to the vtkGDCMImageReader to detect YBR, INVERSE_LUMINANCE and LOOKUP TABLE
  • vtkGDCMImageReader: support 32bits pixel size image
  • vtkGDCMImageReader: always do inplace operation to avoid extra memcpy of image (only an extra line is needed to execute the Y-Flip)
  • New filter: vtkImageYBRToRGB


GDCM 2.0.4

  • Better support for spacing computation in Enhance CT & Enhance MR dataset
  • Fix ZSpacing computation in gdcm::IPPSorter
  • Initial implementation of gdcm::Terminal to support win32 system (console vs vt100-compatible term)

  • gdcm::Orientation implementation

And a whole bunch of bug fixes !


GDCM 2.0.5

=> svn merge -r 3013:3387

  • Fix issues with reading Enhanced MR/CT Image Storage (IOP and IPP): Z-spacing was incorrect, Intercept/Slope were discared.
  • Fix issues with writing Enhanced MR/CT Image Storage (IOP and IPP): Image Position (Patient) needs to be duplicate in the Per Frame SQ, Image Orientation (Patient) & Spacing needs to be in the Shared SQ.
  • Fix issue with deflate syntax
  • Bug fix: vtkImageData::Origin is not Image Position (Patient) when doing VTK-flip
  • Big Endian machine are passing 95% of tests now.
  • First pass at implementing DICOM Part 3 (accessible from python!)

  • Can now build debug gdcm/python with release python (default behavior)
  • Completely fix issues with shift/scale for both reading and writing. Nightly check is done at bit level to verify no floating point error occured.
  • Somewhat better install scheme when host & target are the same (detect python install path and install in proper site-package).
