A new version of Imebra, the open source Dicom library , has been released.

The following changes have been introduced:

Changes since version 0.0.29 (Alpha)

• Now the library doesn't fail when the dataset has an empty images' offset table
• Now the Dicom codec doesn't switch to implicit datatype when a tag without datatype is found in the group 0x0002.
  The tag without datatype is still recognized. This solves a problem with dicom files generated by DicomWorks

Changes since version 0.0.28 (Alpha)

• Added the function puntoexe::imebra::handlers::data::getBufferSize()
• Added the function puntoexe::imebra::buffer::getBufferSizeBytes()
• Now the functions in puntoexe::imebra::dataSet that need the buffer size use the new buffer's functions instead of retrieving a data handler

Changes since version 0.0.27 (Alpha)

• Breaking change: introduced the puntoexe::streamReader and the puntoexe::streamWriter to control the puntoexe::baseStream objects
• Breaking change: now puntoexe::imebra::dataSet throws the exception puntoexe::imebra::dataSetImageDoesntExist when a non existing frame is requested with puntoexe::imebra::dataSet::getImage()
• corrected a bug that was crashing the library when an empty tag was read
• corrected a bug that was causing a deadlock when puntoexe::WaitForMultipleObjects was used (used by the transactions)
• Added the load on demand for the bigger tags
• Now the library handles correcly the images that are fragmented in several data items
• Improvement in the Jpeg codec's performances
• Now image::create() returns a writable datahandler: this avoid the need to ask for a writable data handler and improves the speed
• added puntoexe::memoryPool::flush()
• now the stream names can be in unicode format

Changes since version 0.0.26 (Alpha)

• Corrected the sample Let's read an image
• Corrected a bug in the memoryManager's destructor
• Now the memory manager's parameters can be configured with preprocessor definitions

Changes since version 0.0.25 (Alpha)

• Replaced "informations" with "information" and "infos" with "info"
  The function exceptionsManager::getExceptionInfos became exceptionsManager::getExceptionInfo
  The function exceptionsManager::clearExceptionInfos became exceptionsManager::clearExceptionInfo
• Corrected an issue in the RLE Dicom codec:
  after reading a segment the decoder was seeking to the wrong position in the dicom file, while writing it was writing wrong offsets
• Improved performances in the Jpeg IDCT function

Changes since version 0.0.24 (Alpha)

• Introduced common lock objects
• Introduced the transactions
• Compiles also on Embedded Visual C++ 4 (requires STLPORT, see sourceforge.net/projects/stlport)
• Introduced the view helper class

Changes since version 0.0.22 (Alpha)

• Introduced support for Unicode and different dicom charsets
• Modified several files to solve problems with Borland C++ Builder 2006
• The dicom codec now uses a dataHandlerRaw to read the tags from the file (previously it was using a normal dataHandler)
• Updated the documentation
• Modified the exceptionManager: now it store a list of objects instead of a list of strings

Changes since version 0.0.21 (Alpha)

• Corrected the transformHighBit class
• Modified the exceptionsManager (now it stores the messages per thread and not per exception)
