Hi, I think I found a possible bug with image magick, if you can take a moment to look into it, that would be great.


Thank you

BUG:
With perl magick; $image->Rotate() seams to mess up $image->Get('page')

OUTPUT:
[3:16pm]/home/daniel>perl page_bug.pl
Image::Magick::VERSION = 6.3.3
Original: (this should work)
100x100+0+0
90deg: (this should work)
100x100+99+0
45deg: (yikes! No page size)
0x0+99+0

CODE:

#!/usr/bin/perl
use strict;
use warnings;
use Image::Magick;

print "Image::Magick::VERSION = $Image::Magick::VERSION\n";

my $image = Image::Magick->new();
print STDERR $image->Set('page'=>'100x100');
print STDERR $image->Read('xc:white');

print "Original: (this should work)\n";
print join 'x', $image->Get('page');
print "\n";

print STDERR $image->Rotate(degrees=>90);

print "90deg: (this should work)\n";
print join 'x', $image->Get('page');
print "\n";

print STDERR $image->Rotate(degrees=>45);

print "45deg: (yikes! No page size)\n";
print join 'x', $image->Get('page');
print "\n";

The 0x0 means that the 'virtual' page size is now undefined, and the actual page size and offsets should be used as appropriate.

That has always been the case!
