in reply to Comments and suggestions on new module

I've noticed in almost every method that you had "if it's GD, do A, if it's Imager, do B, etc.." This screams to me that you need to do some deeper encapsulation.

I would propose that you have Image::Mate::(GD|Imager|Image::Magick) and when new() is called bless your object to the user's preference.

Just my 2 cents.

    Ok... Care to elaborate with a quick code example?
      package X; our $PREF; sub new { bless {}, $PREF; } package A; sub foo { print __PACKAGE__; } package B; sub foo { print __PACKAGE__; } package main; $X::PREF = 'B'; my $o = X->new; $o->foo;

      Prints:

      B

      You can change $X::PREF = line to 'A' and it will print A.

        I see. I update with this style in my next release, glad I didn't add to many more features now.
