/**
* /brief File Read/Writer specific for the TestAllReadCompareDicom test
* /remarks The Test file format is (only in little endian) :
* - 4 bytes : size X
* - 4 bytes : size Y
* - 4 bytes : size Z
- * - 2 bytes : scalar size (8,16,32)
- * - 2 bytes : number of components per pixel (1,2,3)
- * - n bytes : datas
+ * - 2 bytes : scalar size (8,16,32) --> ?!? 1 or 2 only in DICOM V3 !
+ * - 2 bytes : number of components per pixel (1,2,3) ---> 1 or 3 only in DICOMV3 !
+ * - n bytes : data
