+ * src/gdcmDocument.cxx : fix bug... test if the fp is opened to use it
+ * src/gdcmPixelConvert.cxx : calculate the image size when while the grab of
+ the header.
+ * src/gdcmFile.[h|cxx] : remove PixelRead and ImageDataSizeRaw variables and
+ some corresponding methods. Write correctly the file and check before
+ write
+ * Test/TestCopyDicom.cxx, TestReadWriteReadCompare.cxx,
+ TestAllReadCompareDicom.cxx : pass the write of images to RGB and test
+ is now on RGB datas (as before my last commit
+ * Example/PrintHeader.cxx, PrintFile.cxx : repad files.

2004-11-24 Benoit Regrain <Benoit.Regrain@creatis.insa-lyon.fr>
* src/gdcmBinEntry.cxx, gdcmSeqEntry.cxx, gdcmSQItem.cxx, gdcmValEntry.cxx :
