I can't reproduce this behavior, however (tested with PHP 5.5.20 and 5.6.15 on Windows). If you still experience this problem on recent PHP versions, please provide the image (img.png) you've used. BTW: the $threshhold and $color arguments are needed only if $mode==IMG_CROP_THRESHOLD. ------------------------------------------------------------------------ [2015-03-04 12:07:12] omid dot khodatars at gmail dot com Description: ------------ --- From manual page: http://www.php.net/function.imagecropauto --- Test script: --------------- here is the code $ini_filename = 'img.png'; $im = imagecreatefrompng($ini_filename ); $to_crop_array = array('x' =>310 , 'y' => 0, 'width' => 573, 'height'=> 500); $thumb_im = imagecropauto($im ,IMG_CROP_WHITE , .5 ,-1 ); // $thumb_im = imagecrop($im, $to_crop_array); imagepng($thumb_im, 'imgOut.png', 9); and here is the error Warning: imagepng() expects parameter 1 to be resource, boolean given in ... on line 9 it is working fine with imagecrop() by the way. ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=69182&edit=1
