simpleimage.php - Error: Call to undefined function imagecreatefromjpeg()

[beemer832]

I am working with the simpleimage.php script to allow me to create two separate images from one uploaded image. I keep getting the following error in my httpd error logs: PHP Fatal error:  Call to undefined function imagecreatefromjpeg() in /var/www/html/classifieds/SimpleImage.php on line 31.

 

I just upgraded to php 5.2.13 after reading an issue with the GD library and support for JPEG's in 5.2.12. This did not fix the issue.

class SimpleImage {
   
   var $image;
   var $image_type;

   function load($filename) {
      $image_info = getimagesize($filename);
      $this->image_type = $image_info[2];
      if( $this->image_type == IMAGETYPE_JPEG ) {
         $this->image = imagecreatefromjpeg($filename);
      } elseif( $this->image_type == IMAGETYPE_GIF ) {
         $this->image = imagecreatefromgif($filename);
      } elseif( $this->image_type == IMAGETYPE_PNG ) {
         $this->image = imagecreatefrompng($filename);
      }
   }
   function save($filename, $image_type=IMAGETYPE_JPEG, $compression=75, $permissions=null) {
      if( $image_type == IMAGETYPE_JPEG ) {
         imagejpeg($this->image,$filename,$compression);
      } elseif( $image_type == IMAGETYPE_GIF ) {
         imagegif($this->image,$filename);         
      } elseif( $image_type == IMAGETYPE_PNG ) {
         imagepng($this->image,$filename);
      }   
      if( $permissions != null) {
         chmod($filename,$permissions);
      }
   }
   function output($image_type=IMAGETYPE_JPEG) {
      if( $image_type == IMAGETYPE_JPEG ) {
         imagejpeg($this->image);
      } elseif( $image_type == IMAGETYPE_GIF ) {
         imagegif($this->image);         
      } elseif( $image_type == IMAGETYPE_PNG ) {
         imagepng($this->image);
      }   
   }
   function getWidth() {
      return imagesx($this->image);
   }
   function getHeight() {
      return imagesy($this->image);
   }
   function resizeToHeight($height) {
      $ratio = $height / $this->getHeight();
      $width = $this->getWidth() * $ratio;
      $this->resize($width,$height);
   }
   function resizeToWidth($width) {
      $ratio = $width / $this->getWidth();
      $height = $this->getheight() * $ratio;
      $this->resize($width,$height);
   }
   function scale($scale) {
      $width = $this->getWidth() * $scale/100;
      $height = $this->getheight() * $scale/100; 
      $this->resize($width,$height);
   }
   function resize($width,$height) {
      $new_image = imagecreatetruecolor($width, $height);
      imagecopyresampled($new_image, $this->image, 0, 0, 0, 0, $width, $height, $this->getWidth(), $this->getHeight());
      $this->image = $new_image;   
   }      
}
?>

 

Then I am using this to actually change my file sizes in another script:

<?
//Convert full size image to 1-thumbnail size 2-similar size for all images. files will be saved in corresponding folders//

include('SimpleImage.php');
   $image = new SimpleImage();
   $image->load('uploads/screenshot.jpg');
   $image->resize(175, 115);
   $image->save('/images/thumb/screenshot.jpg');
?>

 

Let me know if I missed anything, only posted here a few times. Also I am VERY new to PHP, only been coding for about a month now.

 

Thanks

Have you tried '=' instead of '->'?

I just copied and pasted the examples listed on the website for the script.

 

thanks

What does a phpinfo(); statement show in the "gd" section for the GD Version and JPEG Support?

[beemer832]

interesting... there isn't a GD section.......

there isn't a GD section.......

 

There you go. That would explain why the gd functions your code called are not defined.

[beemer832]

Okay well that explains why it isn't working correctly.

 

So now my question is, how do I get this version of PHP to support GD? I did a yum update php to install the newest version. Running Centos 5.

 

thanks josh

[beemer832]

got the first issue squared away by running "yum install php-gd" (centos 5)

 

That downloaded and installed GD support for PHP, then had to restart Apache for changes to take affect.

 

Now I have a few more issues, but haven't had a chance to dig into them yet. Thanks for everyones help
