#23177 [NEW]: imagecreatefromgd2 consumes too much memory

From: alberty at neptunelabs dot de Operating system: i686-pc-linux-gnu PHP version: 4CVS-2003-04-12 (stable) PHP Bug Type: GD related Bug description: imagecreatefromgd2 consumes too much memory Hi, i've found a bug with handling gd2 images. The problem is affected with the bundled libgd (2.0.12). I've convert an image (4932x3543 pixel) with the pngtogd2 tool: ./pngtogd2 mytestpic.png mytestpic.gd2 4932 2 My memory limit is (php.ini): memory_limit = 162M The script: <?php $filename='mytestpic.gd2'; $image=imagecreatefromgd2($filename); ?> results an wrong error message: Fatal error: Allowed memory size of 169869312 bytes exhausted at (null):0 (tried to allocate 22581552 bytes) At first, 22581552 bytes is only the filesize of the mytestpic.gd2 file. Also it shouldn be a problem to load an image with 4932x3543 pixel, because this image need no more than 69896304 bytes (3+1 channels).
