/**
- * \brief Debug is an object for debugging in program.
- * It has 2 debugging modes :
+ * \brief Debug is an object for warning/logging/tracing programs.
+ * It has the following modes :
* - error : for bad library use, seriously wrong DICOM
* - debug : for information/debug messages
- * - warning : for warning about DICOM quality (kosher)
+ * - warning : Warns the user when some oddity occured.
+ * - log : we display messages when anything is not Dicom Kosher
+ * - debug : we help developper to trace, at a glance, the execution
* - assert : design by contract implementation. A function should have
* proper input and proper output.
* (should not happen, not user controlled)
* A debugging message is only shown if the flag is on (DebugFlag)
* This is static var and can be set at beginning of code:
* gdcm::Debug::SetDebugOn();
+ *
+ * Warning : Warns the user when some oddity occured, and we used an heuristics
+ * to bypass the trouble.
+ * e.g. : SamplesPerPixel missing, we assume it's a grey level image
+ * e.g : Pixel Representation missing : we assume 'unsigned'
+ * (we hope our assumption is OK, but user may disagree.)
+ * Log : we display messages when anything is not Dicom Kosher
+ * e.g. : non even length field
+ * e.g : file is declared as Explicit VR, but a DataElement
+ * is Implicit
+ * e.g : a file holds an illegal group (0x0005, ...)
+ * Debug : We help developper to trace, at a glance, the execution.
+ * (before refining with a debugging tool)
+ *
+ * Setting ON Debug leads to set ON Warning (but not Log)
+ * Setting ON Log leads to set ON Warning (but not Debug)
