note 119756 added to imagick.newimage

It's not obvious and may be related only to some specific versions of ImageMagick (tested only for 6.7.7 and 6.8.9), but $cols and $rows must be a positive non-zero value. <?php $image = new Imagick(); $image->newImage(0, 100, new ImagickPixel('red')); $image->setImageFormat('png'); file_put_contents('image.png', $image); ?> In this case imagemagick will crash without throwing any exception and you'll get something along the lines (in your apache error log or console output): unable to acquire cache view `No such file or directory' @ fatal/cache-view.c/AcquireAuthenticCacheView/121. This might be the case when you calculate $cols and $rows (say, based on user input and predefined target image DPI): <?php $image = new Imagick(); $img->newImage($userInput->getWidth() * $defaultPpi, $userInput->getHeight() * $defaultPpi, new ImagickPixel('white')); ?> In this case if user requested image with 0.006 width (in inches), the code would work for $defaultPpi = 300 ppi, but would crash for $defaultPpi = 72 ppi ---- Server IP: 72.52.91.14 Probable Submitter: 81.177.125.226 ---- Manual Page -- http://php.net/manual/en/imagick.newimage.php Edit -- https://master.php.net/note/edit/119756 Del: integrated -- https://master.php.net/note/delete/119756/integrated Del: useless -- https://master.php.net/note/delete/119756/useless Del: bad code -- https://master.php.net/note/delete/119756/bad+code Del: spam -- https://master.php.net/note/delete/119756/spam Del: non-english -- https://master.php.net/note/delete/119756/non-english Del: in docs -- https://master.php.net/note/delete/119756/in+docs Del: other reasons-- https://master.php.net/note/delete/119756 Reject -- https://master.php.net/note/reject/119756 Search -- https://master.php.net/manage/user-notes.php
