The Image Data Stream Format (Function Set 10) for bi-level images. This function set is carried by the MO:DCA and IPDS controlling environments. The permissible parameter groupings in FS10 are defined as follows:
Function Set 10 Structure;
0x70 Begin Segment parameter
0x91 Begin Image Content parameter
+ 0x94 Image Size parameter
+ [ 0x95 Image Encoding parameter ]
+ [ 0x96 IDE Size parameter ]
0xFE92 Image Data (S)
0x93 End Image Content parameter
0x71 End Segment parameter
The self-defining fields and values acceptable for FS10 are shown in the following table;
