=head1 SYNOPSIS |
13
|
|
|
|
|
|
|
|
14
|
|
|
|
|
|
|
This class inherit everything from L and |
15
|
|
|
|
|
|
|
only alters the C method to rotate the pages by 90 degrees. |
16
|
|
|
|
|
|
|
Please refer to the parent class for method documentation. |

=head1 SCHEMA EXPLANATION |
19
|
|
|
|
|
|
|
|
20
|
|
|
|
|
|
|
First go and read the schema explanation in |
21
|
|
|
|
|
|
|
L (or better, the whole documentation). |
22
|
|
|
|
|
|
|
It's the same dynamic kind of imposition. |
23
|
|
|
|
|
|
|
|
24
|
|
|
|
|
|
|
The only difference is that each I page is rotated by 90 |
25
|
|
|
|
|
|
|
degrees counter-clockwise, so a signature of 4 pages looks so: |
26
|
|
|
|
|
|
|
|
27
|
|
|
|
|
|
|
+------+------+ +------+------+ |
28
|
|
|
|
|
|
|
| 4 | 1 | | 2 | 3 | |
29
|
|
|
|
|
|
|
+------+------+ +------+------+ |
30
|
|
|
|
|
|
|
|
31
|
|
|
|
|
|
|
Now, showing the number rotated by 90 degrees is a bit complicated in |
32
|
|
|
|
|
|
|
ASCII-art, but each logical page is B, so |
33
|
|
|
|
|
|
|
you have to bind it on the short edge (and the final product will look |
34
|
|
|
|
|
|
|
much more like a notepad than a booklet, as the binding will fall on |
35
|
|
|
|
|
|
|
the top edge). |
36
|
|
|
|
|
|
|
|
37
|
|
|
|
|
|
|
I find this schema odd, but I provide it nevertheless. |
