Does anyone know how to specify lengths of AC and DCTables for JPEG compressed image ( in TIFF )

The tags JPEGACTABLES(208.H) and JPEGDCTABLES(209.H) point to lists of offsets to Huffman tables but the tables themselves can be of varying lengths. For eg. The DCTables can be *upto* 33 bytes long.

How do i specify the exact length of the table?? What am i missing??

Thanx in advance!!
