Hi,
Examining the margins hack i see that it'll be not so difficult to reproduce the hack in other language. But I've some doubts,
The diferrences between the hacked margins and the original file are the next ones, original left, modified right:
$0A will be the 10 Margin
$14 the 20 Margin
$1E the 30 Margin
$12 the 18 bottom
$0C the 12 Top
?? the 36 for pdf, i don't see this one.
But there are other changes, at 45F0 one byte is added 00, and to the end 18 bytes were removed.
What do you use to edit compiled class files?
Thx for the hack, a very interesting one.
