Yes, it passed the test. Here is the simplest possible script with a gd oo
interface that fails on my computer (64-bit) but works on my server (32-bit).
The version of Perl and PDL are both identical on both machines, both custom
installed by me.
use PDL::Lite;
use PDL::Primitive;
use PDL::IO::GD;
my $pdl = (random(400, 400) * 7)->floor;
my $lut = pdl (
[ 0, 0, 0], # black for borders
[136, 136, 136], # grey for transparent
[ 26, 150, 65], # dark green
[166, 217, 106], # light green
[255, 255, 191], # yellow
[253, 174, 97], # orange
[215, 25, 28], # red
);
gd_reg(); # works
gd_oo(); # segfaults
# Using OO
sub gd_oo {
PDL::IO::GD->new(
{pdl => $pdl, lut => $lut}
)->write_Png( 'test_oo.gif' );
}
# Using non-OO
sub gd_reg { write_png($pdl, $lut, 'test_reg.gif'); }
