One more problem after update

Hello, guys.

Please, explain the issue.
After update from 6.4.6 to 6.5.6-10 there is a strange behavior of the "Scale" function for PNG image with transparency. After making "Scale" and "Composite" white border appears.

Here is how it have to work, example from 6.4.6 (click to enlarge)


And here is script that was used

Code: Select all

#!/usr/bin/perl

use strict;
use Image::Magick;

my $res = undef;

my $img_back = Image::Magick->new();
$img_back->Read('photo.jpg');

my $img_front = Image::Magick->new();
$img_front->Read('front.png');
$img_front->Scale( geometry => '200x' );

$img_back->Composite( image => $img_front, geometry => '+200+250' );

$img_back->Write( 'pic.jpg' );

It looks like there is a problem with Scale(). Use Resize() until we come up with a patch.
