// Each decodeTable is represented by an array of [2]int16's: a binary tree.
|
|
|
|
|
// Each array element (other than element 0, which means invalid) is a branch
|
|
|
|
|
// node in that tree. The root node is always element 1 (the second element).
|
|
|
|
|
//
|
|
|
|
|
// To walk the tree, look at the next bit in the bit stream, using it to select
|
|
|
|
|
// the first or second element of the [2]int16. If that int16 is 0, we have an
|
|
|
|
|
// invalid code. If it is positive, go to that branch node. If it is negative,
|
|
|
|
|
// then we have a leaf node, whose value is the bitwise complement (the ^
|
|
|
|
|
// operator) of that int16.
|
|
|
|
|
//
|
|
|
|
|
// Comments above each decodeTable also show the same structure visually. The
|
|
|
|
|
// "b123" lines show the 123'rd branch node. The "=XXXXX" lines show an invalid
|
|
|
|
|
// code. The "=v1234" lines show a leaf node with value 1234. When reading the
|
|
|
|
|
// bit stream, a 0 or 1 bit means to go up or down, as you move left to right.
|
|
|
|
|
//
|
|
|
|
|
// For example, in modeDecodeTable, branch node b005 is three steps up from the
|
|
|
|
|
// root node, meaning that we have already seen "000". If the next bit is "0"
|
|
|
|
|
// then we move to branch node b006. Otherwise, the next bit is "1", and we
|
|
|
|
|
// move to the leaf node v0000 (also known as the modePass constant). Indeed,
|
|
|
|
|
// the bits that encode modePass are "0001".
|
|
|
|
|
//
|
|
|
|
|
// Tables 1, 2 and 3 come from the "ITU-T Recommendation T.6: FACSIMILE CODING
