Using the same code in Gentoo gives expected result. Example Code: <?php // Create a 300x300px transparant image with a 100px wide red circle in the middle $i = imagecreatetruecolor(300, 300); imagealphablending($i, FALSE); imagesavealpha($i, TRUE); $transparant = imagecolorallocatealpha($i, 0xDD, 0xDD, 0xDD, 0x7F); imagecolortransparent($i, $transparant); imagefill($i, 0, 0, $transparant); $red = imagecolorallocate($i, 0xFF, 0x0, 0x0); imagefilledellipse($i, 150, 150, 100, 100, $red); imagepng($i, "red_300.png"); // Crop away transparant parts and save $i2 = imagecropauto($i, IMG_CROP_TRANSPARENT); imagepng($i2, "red_crop_trans.png"); imagedestroy($i2); // clean up org image imagedestroy($i); Expected result: * red_300.png: 300x300px, transparant with a 100x100px red circle * red_crop_trans.png: 100x100px, transparant with a 100x100px red circle Ubuntu Result: * red_300.png: 300x300px, transparant with a 101x101px red circle * red_crop_trans.png: 101x101px, black with a 101x101px red circle Gentoo result: * red_300.png: 300x300px, transparant with a 101x101px red circle * red_crop_trans.png: 101x101px, transparant with a 101x101px red circle Ubuntu versions: lsb_release -d -> 'Ubuntu 16.10' php -v -> 'PHP 7.0.8-3ubuntu3' apt-cache show php-gd > '1:7.0+44' apt-cache show php7.0-gd -> '7.0.8-3ubuntu3' apt-cache show libgd3 -> '2.2.1-1ubuntu3.2', '2.2.1-1ubuntu3' uname -r -> '4.8.0-26-generic' Gentoo versions: uname -r -> '4.1.12-gentoo' php -v -> 'PHP 5.6.26-pl0-gentoo' equery list gd -> 'media-libs/gd-2.1.1-r1' To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/apport/+bug/1641307/+subscriptions -- Mailing list: https://launchpad.net/~touch-packages Post to : touch-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~touch-packages More help : https://help.launchpad.net/ListHelp
