Bug #27636 [Com]: imagecreatefromjpeg fails if the picture is too high

Edit report at https://bugs.php.net/bug.php?id=27636&edit=1 ID: 27636 Comment by: phpbugs at juracid dot co dot uk Reported by: mito at nic dot fi Summary: imagecreatefromjpeg fails if the picture is too high Status: Closed Type: Bug Package: GD related Operating System: FreeBSD 4.8-RELEASE #0 PHP Version: 4.3.4 Block user comment: N Private report: N New Comment: For the confused, JPEGs are compressed, the image created by imagecreatefromjpeg() is a raw (uncompressed) one so the size will be approximately width * height * 3 That's assuming 3 bytes / 24 bits per pixel, 8-bits for each of R,G,B, in reality using width * height * 4 might be safer.

I just wonder how a smaller pic can take more memory.. ------------------------------------------------------------------------ [2004-03-18 13:29:18] pajoye@php.net Hello, both work perfectly here. Either using cli, or apache, php5 or php4. Please add the memory_limit option to your php.ini. Default is 8M, try more. pierre ------------------------------------------------------------------------ [2004-03-18 13:25:56] mito at nic dot fi Image that works: Dimensions: 1600x1200 Size on disk: 575KB Image that doesn't work: Dimensions: 1200x1600 Size on disk: 491KB ------------------------------------------------------------------------ [2004-03-18 13:18:21] mito at nic dot fi That is not the case. The test pic I provided that the code works with is larger than the pic that causes the failure. Therefor if it were up to the picture being too large and using too much memory it would occur with the larger picture too wouldn't it? ------------------------------------------------------------------------ [2004-03-18 12:29:37] iliaa@php.net Thank you for taking the time to write to us, but this is not a bug. Please double-check the documentation available at http://www.php.net/manual/ and the instructions on how to report a bug at http://bugs.php.net/how-to-report.php You probably have a memory_limit enabled and it is reached trying to allocate memory to store a big image. ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
