[Bug 1669734] Re: Quality decrease in libgd3 with upgrade to 2.1.1-4ubuntu0.16.04.5
That commit is for when PHP is built with the embedded libgd. But in Ubuntu, PHP is using the system libgd instead of the one built in with PHP. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1669734 Title: Quality decrease in libgd3 with upgrade to 2.1.1-4ubuntu0.16.04.5 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/libgd2/+bug/1669734/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

For reference, bug referred is «Fixed bug #45030 (Destination image alpha channel noise when using imagecopyresampled). (Pierre)» from php-5.3.0beta1 release notes.

Hi, I've been digging for this bug for a few weeks now. The first report of it is from ... 2008, in php.net: https://bugs.php.net/bug.php?id=45030 But it was fixed, because the same code on another distribution (in my case Gentoo) doesn't happen. Can anyone look into this bug? This issue has been open since 2017 and it still exists on the latest version of PHP 7.4 on Ubuntu 20. ** Bug watch added: bugs.php.net/ #45030 http://bugs.php.net/bug.php?id=45030 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1669734 Title: Quality decrease in libgd3 with upgrade to 2.1.1-4ubuntu0.16.04.5 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/libgd2/+bug/1669734/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Since the last upgrade of the php7.0-gd package the workaround with the old version doesn't work perfectly anymore. Using the new php7.0-gd with the old libgd3 creates bad borders on some images. With the current libgd3 this behavior doesn't appear, but the strange background isn't fixed yet. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1669734 Title: Quality decrease in libgd3 with upgrade to 2.1.1-4ubuntu0.16.04.5 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/libgd2/+bug/1669734/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

I had the same issue when using imagecopyresampled() to resize PNG images with transparent background. It introduced subtle noise to the transparent background in the resulting image. It looks like some kind of rounding issue within the resampling algorithm. As a temporary workaround, reverting libgd back to 2.1.1-4build2 resolves the problem. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1669734 Title: Quality decrease in libgd3 with upgrade to 2.1.1-4ubuntu0.16.04.5 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/libgd2/+bug/1669734/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
