Hello!
I would imagine that the output PDL from this code ($o) would be
identical to the input ($i):
use PDL;
use PDL::Transform;
my $i = sequence(5,5) + sequence(5,5)->transpose;
my $o = $i->map(t_identity,{pix=>1,phot=>'flux',method=>'sample'});
Instead I get:
print $i-$o;
[
[-12 -12 -12 -12 24]
[-12 -12 -12 -12 30]
[-12 -12 -12 -12 36]
[-12 -12 -12 -12 42]
[ 24 30 36 42 48]
]
that is, the transformed PDL has been shifted by (-1,-1). Any
explanation for this? Perhaps I am not using map() correctly?
I got this result by running PDL-2.4.3 on a linux (gentoo 2006.1)
machine.
Cheers,
Rahman
