I am trying to transpose the NUp example in Chapter 6 (p. 171) of the
2E book to ColdFusion, but having an issue with the calculation of the
offsets.
Is it possible to get an explanation of what the helper variables "n",
"r", "c", represent in that example? I can tell that the "n"
represents the number of documents that should be printed per page,
but can't seem to determine "r" and "c".
In the example pow can be 1, 2, 3, 4.
These are the corresponding values for n, r and c:
pow = 1: 2-up => 1 x 2
pow = 2: 4-up => 2 x 2
pow = 3: 8-up => 2 x 4
pow = 4: 16-up => 4 x 4
If you look at figure 6.5, you immediately see what 1 x 2, 2 x 2, 2 x 4
and 4 x 4 mean.
