PHP Image crop

[jamiet757]

I am trying to set up something on my site that will use PHP to crop an image and display it, so that all the images are the same size, but are not squished or distorted. Here is the code I found:

 

<?php
var $imgSrc,$myImage,$cropHeight,$cropWidth,$x,$y,$thumb;  

function setImage($image)
{

//Your Image
   $this->imgSrc = $image; 
                     
//getting the image dimensions
   list($width, $height) = getimagesize($this->imgSrc); 
                     
//create image from the jpeg
   this->myImage = imagecreatefromjpeg($this->imgSrc) or die("Error: Cannot find image!"); 
            
       if($width > $height) $biggestSide = $width; //find biggest length
       else $biggestSide = $height; 
                     
//The crop size will be half that of the largest side 
   $cropPercent = .5; // This will zoom in to 50% zoom (crop)
   $this->cropWidth   = $biggestSide*$cropPercent; 
   $this->cropHeight  = $biggestSide*$cropPercent; 
                     
                     
//getting the top left coordinate
   $this->x = ($width-$this->cropWidth)/2;
   $this->y = ($height-$this->cropHeight)/2;
             
} 

function createThumb()
{
                    
  $thumbSize = 250; // will create a 250 x 250 thumb
  $this->thumb = imagecreatetruecolor($thumbSize, $thumbSize); 

  imagecopyresampled($this->thumb, $this->myImage, 0, 0,$this->x, $this->y, $thumbSize, $thumbSize, $this->cropWidth, $this->cropHeight); 
}  

function renderImage()
{
                     
   header('Content-type: image/jpeg');
   imagejpeg($this->thumb);
   imagedestroy($this->thumb); 
} 

$image = new cropImage;
$image->setImage($src);
$image->createThumb();
$image->renderImage(); 

?>

 

I found it here: http://www.talkphp.com/advanced-php-programming/1709-cropping-images-using-php.html

 

The problem I am having is with the line that starts with "var". I get this error when I try to access the file:

Parse error: syntax error, unexpected T_VAR

 

I am not exactly sure how to include the var line, or if it is wrong. Can anyone help?

You should go back and read the tutorial again. You missed the most important part.

class cropImage{}

I have that surrounding the area where the image appears, is that not the correct way to do it?

[jamiet757]

i put the class tag around it, hopefully it will work

Well, I still get an error. I fixed a slight problem with a missing $, but I get this error when I try to access thumbcreate.php?src=image.jpg (and yes, the image.jpg file does exist)

 

Fatal error: Cannot access empty property on line 13

 

Here is what I have:

<?php

class cropImage{
var $imgSrc,$myImage,$cropHeight,$cropWidth,$x,$y,$thumb;  

function setImage($image)
{

//Your Image
   $this->imgSrc = $image; 
                     
//getting the image dimensions
   list($width, $height) = getimagesize($this->$imgSrc); 
                     
//create image from the jpeg
   $this->myImage = imagecreatefromjpeg($this->$imgSrc) or die("Error: Cannot find image!"); 
            
       if($width > $height) $biggestSide = $width; //find biggest length
       else $biggestSide = $height; 
                     
//The crop size will be half that of the largest side 
   $cropPercent = .5; // This will zoom in to 50% zoom (crop)
   $this->cropWidth   = $biggestSide*$cropPercent; 
   $this->cropHeight  = $biggestSide*$cropPercent; 
                     
                     
//getting the top left coordinate
   $this->x = ($width-$this->cropWidth)/2;
   $this->y = ($height-$this->cropHeight)/2;
             
} 

function createThumb()
{
                    
  $thumbSize = 80; // will create a 80 x 80 thumb
  $this->thumb = imagecreatetruecolor($thumbSize, $thumbSize); 

  imagecopyresampled($this->thumb, $this->myImage, 0, 0,$this->x, $this->y, $thumbSize, $thumbSize, $this->cropWidth, $this->cropHeight); 
}  

function renderImage()
{
                     
   header('Content-type: image/jpeg');
   imagejpeg($this->thumb);
   imagedestroy($this->thumb); 
} 
}
$image = new cropImage;
$image->setImage($src);
$image->createThumb();
$image->renderImage(); 

?>

 

Can anyone help me get this script working? I can figure out a few things with php, but my knowledge is limited.

Tryh being a bit more specific with the image src.

thumbcreate.php?src="./image.jpg"

or

thumbcreate.php?src="$url/image.jpg"

or

thumbcreate.php?src="http://location.of/image.jpg"

 

cause it seems that the $imgSrc is not giving up the image.

I tried your suggestions, but to no avail

 

I think the problem lies in this line (obviously since it says so in the error message)

  $this->imgSrc = $image;

 

I don't understand where it is getting the $image from, it is not referenced anywhere else.

Can anyone help me out with this one?
