+/** \defgroup raw RAW - RAW File
+ * 
+ * \par
+ * The file must be open/created with the functions \ref imFileOpenRaw and \ref imFileNewRaw.
+ * 
+ * \section Description
+ * 
+ * \par
+ * Internal Implementation.
+ * \par
+ * Supports RAW binary images. This is an unstructured and uncompressed binary data. 
+ * It is NOT a Camera RAW file generated in many professional digital cameras. \n
+ * You must know image parameters a priori and must set the IM_INT attributes "Width", "Height", "ColorMode", "DataType" 
+ * before the imFileReadImageInfo/imFileWriteImageInfo functions.
+ * \par
+ * The data must be in binary form, but can start in an arbitrary offset from the begining of the file, use attribute "StartOffset".
+ * The default is at 0 offset. 
+ * \par
+ * Integer sign and double precision can be converted using attribute "SwitchType". \n
+ * The conversions will be BYTE<->CHAR, USHORT<->SHORT, INT<->UINT, FLOAT<->DOUBLE.
+ * \par
+ * Byte Order can be Little Endian (Intel=1) or Big Endian (Motorola=0), use the attribute "ByteOrder", the default is the current CPU.
+ * \par
+ * The lines can be aligned to a BYTE (1), WORD (2) or DWORD (4) boundaries, ue attribute "Padding" with the respective value.
+ * \par
+ * If the compression is ASCII the data is stored in textual format, instead of binary. 
+ * In this case SwitchType and ByteOrder are ignored, and Padding should be 0.
+ * \par
+ * See \ref im_raw.h
+ * 
+ * \section Features
+ *

+    Data Types: <all>
+    Color Spaces: all, except MAP.
+    Compressions: 
+      NONE - no compression [default] 
+      ASCII (textual data)
+    Can have more than one image, depends on "StartOffset" attribute.
+    Can have an alpha channel.
+    Components can be packed or not.
+    Lines arranged from top down to bottom or bottom up to top.
+
+    Attributes:
+      Width, Height, ColorMode, DataType IM_INT (1)
+      ImageCount[1], StartOffset[0], SwitchType[FALSE], ByteOrder[IM_LITTLEENDIAN], Padding[0]  IM_INT (1)
+
+    Comments:
+      In fact ASCII is an expansion, not a compression, because the file will be larger than binary data.
