Lee, Andrew, and Ken,
Thanks for the help. It looks like the problem originated in a config file that I wrote in php. I removed the closing '?>' and now my images are being displayed correctly. -D ----- Original Message ---- From: Ken Stanley <[EMAIL PROTECTED]> To: Don Reeves <[EMAIL PROTECTED]>; [email protected] Sent: Tuesday, December 26, 2006 2:42:23 PM Subject: Re: [fw-general] dynamic image generation Good day. I've been watching the list for a little while now, but I think now would be a good time to jump in with a suggestion. Don, I am going to assume that you are not viewing a 'typical' web page (one that contains HTML, etc), but instead you are trying to view the script itself that is trying to generate the image. If this is the case, then there is no source to view as aforementioned by Lee. What you can try to do is to turn on E_ALL error reporting, and then comment out the line of code you are using to output the Content-Type for your image. If there are errors, this should allow you to see them, along with the contents of the image itself. When you set an image header, the web browser doesn't treat it like a typical file, therefor in most cases -- at least the ones I've dealt with -- you won't see your PHP errors in the output. I hope this helps. :) On 12/26/06, Don Reeves <[EMAIL PROTECTED]> wrote: I have actually tried to 'view source' but the option is not available when I am viewing this page. ----- Original Message ---- From: Lee Saferite < [EMAIL PROTECTED]> To: Don Reeves <[EMAIL PROTECTED]>; Zend Framework General < [email protected]> Sent: Tuesday, December 26, 2006 8:17:56 AM Subject: Re: [fw-general] dynamic image generation Generally, in firefox, you can 'view source' and get the actual error message the server sent. Send us that error please. Lee On 12/25/06, Don Reeves <[EMAIL PROTECTED]> wrote: Hi, I am new to the Zend Framework but am very happy with what I have seen so far. I have decided to try integrating the framework into an application that I wrote previously. Things have been going smoothly except for some scripts that I have written to handle dynamically displaying images. These images are charts that I use in the application. Here is a script that I have converted into a controller in my application. I access it from a url in the following manner: http://localhost/chart/index/dir/dir123/file/chart123.gif The controller is pretty basic at the moment: class ChartController extends Zend_Controller_Action { function indexAction() { $runDir = $this->_getParam('dir'); $file = $this->_getParam('file'); header("Content-type: image/gif"); $image = imagecreatefromgif(RUNS_DIR . '/' . $runDir . '/' . $file); imagegif($image); imagedestroy($image); } } An almost identical script allowed me to generate the gif images previously. I have also confirmed that the image referenced in imagecreatefromgif is referencing a valid gif file. When I access the url http://localhost/chart/index/dir/dir123/file/chart123.gif , I get the following message: "The image " http://localhost/chart/index/dir/dir123/file/chart123.gif " cannot be displayed, because it contains errors." I am curious if there is anything about the Zend Framework that prevents this image from displaying correctly. I was wondering if it had to do with how I am setting my header but examining the header using Tamper Data for Firefox, the headers seem to be getting set correctly. Can anyone see a problem with my implementation that needs to change to generate images dynamically within the ZF? Thanks for the help.
