From: bug_php at yahoo dot fr Operating system: Linux RedHat 2.4.28 PHP version: 4.3.11 PHP Bug Type: *Graphics related Bug description: 1 pixel missing on imagecopyresized and imagecopyresampled
Description: ------------ See PHP info on http://720plan.ovh.net/test.php (PHP version is 4.3.11 as of 2005/07/23). Bug similar to the problem exposed in closed bug report #26254. The code below results in an image that is 1 pixel too small: there is a blank range of pixels. According to the destination image width and height, this range of pixels can be vertical, horizontal, or both. The code below is for a 640*480 image destination. But the same happens for a 40*40 image for instance. This problem occurs with any image and number of pixels I tried. The only case it works: when the image destination has the same size thant the source image. Reproduce code: --------------- <html> <body bgcolor="green"> <? $image_source_filename="bar.jpg"; //image 230*173px $image_cible_filename="bar.gif"; $ImgSrc = imagecreatefromjpeg ($image_source_filename); imagetruecolortopalette($ImgSrc, false, 256); $ImgDst = imagecreate(640,480); imagecolorallocate($ImgDst, 255, 255, 255); imagecopyresized($ImgDst,$ImgSrc,0,0,0,0,640,480,230,173); imagegif ($ImgDst,$image_cible_filename); echo("<br><br><font color=\"white\">Resized image=</font><br><img src=\"$image_cible_filename\"><br>"); ?> </body> </html> -- Edit bug report at http://bugs.php.net/?id=33836&edit=1 -- Try a CVS snapshot (php4): http://bugs.php.net/fix.php?id=33836&r=trysnapshot4 Try a CVS snapshot (php5.0): http://bugs.php.net/fix.php?id=33836&r=trysnapshot50 Try a CVS snapshot (php5.1): http://bugs.php.net/fix.php?id=33836&r=trysnapshot51 Fixed in CVS: http://bugs.php.net/fix.php?id=33836&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=33836&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=33836&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=33836&r=needscript Try newer version: http://bugs.php.net/fix.php?id=33836&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=33836&r=support Expected behavior: http://bugs.php.net/fix.php?id=33836&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=33836&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=33836&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=33836&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=33836&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=33836&r=dst IIS Stability: http://bugs.php.net/fix.php?id=33836&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=33836&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=33836&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=33836&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=33836&r=mysqlcfg
