+// Wireless Bitmap Format
+// ----------------------
+// The WBMP format enables graphical information to be sent to a variety of handsets.
+// The WBMP format is terminal independent and describes only graphical information.
+
+// IMPLEMENTATION NOTES:
+// ------------------------
+// The WBMP format is configured according to a type field value (TypeField below),
+// which maps to all relevant image encoding information, such as:
+// · Pixel organisation and encoding
+// · Palette organisation and encoding
+// · Compression characteristics
+// · Animation encoding
+// For each TypeField value, all relevant image characteristics are 
+// fully specified as part of the WAP documentation.
+// Currently, a simple compact, monochrome image format is defined
+// within the WBMP type space :
+//
+// Image Type Identifier, multi-byte integer	0
+// Image Format description						0 B/W, no compression
+// -------------------------------------------------------------------------------
