  Thu Oct 11 22:08:47 2007 TONYC [...] cpan.org - Ticket created
Subject: Imager::Matrix2d should either allow addition/multiplication of custom matrices or an initialize from values constructor
Date: Fri, 12 Oct 2007 12:08:24 +1000
To: bug-Imager [...] rt.cpan.org
From: tonyc [...] cpan.org
Trying to build a perspective matrix with some offsets to centre it: my $offset1 = Imager::Matrix2d->translate(x => -$work->getwidth / 2, y => 0); my $persp = [ 1, 0, 0, 0, 1, 0, 0, -0.001, 1 ]; my $offset2 = Imager::Matrix2d->translate(x => $work->getwidth / 2, y => 0); my $matrix = $offset1 * $persp * $offset2; # $matrix undef But since there's no way to build an object the only way to make it work is to break encapsulation and bless the custom matrix into Imager::Matrix2d.
