#38390 [Opn->Fbk]: imagecopyresized's return value not documented

ID: 38390 Updated by: pajoye@php.net Reported By: bigmrpoo at yahoo dot com -Status: Open +Status: Feedback Bug Type: Documentation problem Operating System: WinXP PHP Version: Irrelevant New Comment: It returns true on success and false on error. That's why the return value is defined as bool. The only case where it failed is when you try to pass zero (or negative) width/height. And finally, which issues are you talking about? Previous Comments: ------------------------------------------------------------------------ [2006-08-08 23:20:35] bigmrpoo at yahoo dot com Description: ------------ The documentation page for imagecopyresized does not describe the return value other than stating it is a boolean value. If this is an indicator of success or failure of the operation, then clients of this function must be programmed to behave correctly in case of failure. To do this, we must also know what situations will cause it to fail, and what side effects (if it is not atomic) occur if the operation fails. I tried to point out the clients of this function need to be aware of these issues in the comments for that page, but one of the editors decided to take my points as a question, not as raising a "gotcha" for the users of the function... So now im posting it here.
