failing montage.t test

I get 19/19 tests failed when make test with 6.8.0-10. More testing shows, that:
6.7.8-8 ok
6.7.9-0 ok
6.7.9-1 fail
6.7.9-3 fail
6.7.9-5 fail
6.8.0-0 fail
6.8.0-10 fail

With following test derived from montage.t:

Code: Select all

use Image::Magick;

my $images=Image::Magick->new;
my $image=Image::Magick->new;

my @colors = ( '#000000', '#008000', '#C0C0C0', '#00FF00',
               '#808080', '#808000', '#FFFFFF', '#FFFF00',
               '#800000', '#000080', '#FF0000', '#0000FF',
               '#800080', '#008080', '#FF00FF', '#00FFFF' );

my $color;
foreach $color ( @colors ) {

  $image->Set(size=>'50x50');
  $status=$image->ReadImage("xc:$color");
  if ("$status") {
    warn "Readimage: $status" if "$status";
  } else {
    push( @$images, @$image);
  }
  undef @$image;
}

my $montageOptions=q/background=>'#696e7e', label=>''/;
eval "\$montage=\$images->Montage( $montageOptions ) ;";

$signature=$montage->GetAttribute('signature');
print "signature: $signature\n";
I get:

All on the same build system (changeroot).
Could you please advise?

And the issue persists with 6.8.1-0.

Anyway, happy Christmas!

The tests pass for us. Do you have Ghostscript installed? Its required for the unit tests to pass. We'll review the tests on a number of our systems and see if we can reproduce the problem. Thanks.

Thanks for quick reply.

Yes, ghostscript is installed. I have tested ImageMagick-6.7.9-1 (first version which is failing for me) with script from initial comment also on live system and I get again

Code: Select all

test> perl montage-test.pl
signature: 93afa0ad47528ea284a170f6564e9cbb0b824959daf49ada35c43d9e8ca40f79
So the signature is different from that expected one in the test.

With ImageMagick-6.7.8-8 I get expected signature on the _same system_.

If there is something wrong in the dependencies, it must be something which doesn't matter in 6.7.9-0 but in 6.7.9-1 does.

Maybe worth to add, that expected signatures in montage.t have changed at the same point of time when this test started failing for me (i. e. between 6.7.9-0 and 6.7.9-1).

This is interesting.

With 6.7.9-1 as well as with 6.8.1-10, except test 12 and 13, I get same 'computed signatures' as expected ones before
http://trac.imagemagick.org/changeset/9087
!

Notes:
* Computed signatures in the tests 12 and 13 differs also between versions 6.7.9-1 and 6.8.1-10.
* This is with quantum-depth=16. With quantum-depth=8, I get same computed signatures as expected ones before changeset 9087 even for test 12 and 13.

To which change is related test changeset in question?

Hello,

on an OpenSuSE 11.4 System, while building 6.8.2-4 with GS version "GPL Ghostscript 9.00 (2010-09-14)", I also see the same behaviour reported by Petr: the test passes with the signatures present before changeset 9087.

Cheers,

I've released a 6.8.2-4 package for OpenSuSE on the OBS: https://build.opensuse.org/package/show ... vjt%3Aifad. With this, you can programmatically replicate the build environment and analyze what's going on.

Cheers,

~Marcello

We can reproduce the problem you posted and have a patch in ImageMagick 6.8.2-6 Beta available by sometime tomorrow. Thanks.

Much better, thanks!

For quantum depth 8 (not tested other so far), I get 2/19 tests failing now:

$images->Set(bordercolor=>'blue', mattecolor=>'red')
$montage=$images->Montage( background=>'#696e7e',, tile=>'4x4', geometry=>'90x80+3+3>', frame=>'8x10',
borderwidth=>'0', gravity=>'Center', background=>'gray' )
ok 11
$images->Set(bordercolor=>'blue', mattecolor=>'red')
$montage=$images->Montage( background=>'#696e7e',, tile=>'4x4', geometry=>'90x80+6+6>', frame=>'8x10',
borderwidth=>'0', gravity=>'Center', shadow=>'True',background=>'gray' )
ReadImage()
Test 12, signatures do not match.

Test 13, signatures do not match.

not ok 13

Test 11 passes, so probably shadow or geometry parameters used in test 12 makes the difference. Basically, I get same signatures as in
http://trac.imagemagick.org/browser/Ima ... ?rev=11269
for these two tests.

For quantum depth 16, all 19 tests passed in the same build environment.

By the way, maybe it is off-topic, maybe connected: for write.t, I get two test failing too, again for quantum depth 8:

CompuServe graphics interchange format ...
ReadImage()
Image: GIF:input.gif, signatures do not match.
Expected: 0c2e3c82fd375360fba16258bfa83e35b8c878fd208da9818b50e423426cc437

not ok 7
CompuServe graphics interchange format (1987) ...
ReadImage()
Image: GIF87:input.gif87, signatures do not match.
Expected: b68fe02737630f219fbf1f9ef3f24cf2b73c21848443a02df2cc2c0212a65657

not ok 8

So tests related to GIF. And again, I get same signatures as in
http://trac.imagemagick.org/browser/Ima ... /t/write.t

For quantum depth set to 16, I get no test failure.

In pervious two comments, ImageMagick 6.8.4-0 plays the lead role.
