#39780 [Opn->Ana]: Fatal error reported for recoverable error

ID: 39780 Updated by: pajoye@php.net Reported By: pz at mysqlperformanceblog dot com -Status: Open +Status: Analyzed Bug Type: GD related Operating System: Linux PHP Version: 5.2.0 Assigned To: pajoye New Comment: The image is invalid. Either the buffer is incomplete or the CRC is wrong. You can try with different image viewers, the lower part will miss, more or less depending on how tolerant is the reader. It is also important to tell us directly what you provide, like a png named as gif, it minimizes the time we need to test or analyze your problem. If you used imagecreatefromgif it will simply fail, so yes, which functions you use to open this image is important. I will check if returning false is a safe choice. It should be but I need to test it first.

Regarding what function I should use this is not the point - I created simple test case to illustrate problem. In the real script it is used completely different way. ------------------------------------------------------------------------ [2006-12-08 20:02:35] pajoye@php.net Please provide a working link to the image. ------------------------------------------------------------------------ [2006-12-08 20:02:21] iliaa@php.net You really should be using the imagecreatefromgif() function in this instance.
