Bug #71218 [NEW]: imagecropauto introduces black line

From: flip101 at gmail dot com Operating system: Windows 7 64bits PHP version: 5.6.16 Package: GD related Bug Type: Bug Bug description:imagecropauto introduces black line Description: ------------ When cropping an image suddenly a black line appears at the bottom of the image. To demonstrate this you can have a look at https://i.imgur.com/2G6J9iu.png where i combined the cropped and non-cropped in the same image. Of course you can not see the original image borders in this representation. So if it's not clear to you, just run the test script, twice maybe with $img = imagecropauto($img); commented out a second time. I tried viewing with IrfanView 4.37 and Paint.NET 4.0.6 Test script: --------------- <?php $img = imagecreatetruecolor(400, 400); imagefill($img, 0, 0, imagecolorallocate($img, 255, 255, 255)); // white background $blue = imagecolorallocate($img, 0, 0, 255); foreach (range(1, 5) as $font) { imagestring($img, $font, 10, $font * 15, 'test', $blue); } $img = imagecropauto($img); imagepng($img, 'test.png'); -- Edit bug report at https://bugs.php.net/bug.php?id=71218&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=71218&r=trysnapshot54 Try a snapshot (PHP 5.5): https://bugs.php.net/fix.php?id=71218&r=trysnapshot55 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=71218&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=71218&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=71218&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=71218&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=71218&r=needscript Try newer version: https://bugs.php.net/fix.php?id=71218&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=71218&r=support Expected behavior: https://bugs.php.net/fix.php?id=71218&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=71218&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=71218&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=71218&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=71218&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=71218&r=dst IIS Stability: https://bugs.php.net/fix.php?id=71218&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=71218&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=71218&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=71218&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=71218&r=mysqlcfg
