resizing images using php.

[LJackson]

Hi all,

what i am looking for is a script which sets a boundry so to speak for the maximum size of any image e.g 100x100
i dont want the images to be exactly 100x100 but i want them to be resized so that they fit inside a 100x100 boundry.

i have several images of all shapes and sizes and i have tried setting the height='100' which works for images which are vertical but for those where the width is bigger than the height the image is too wide when using height=100.

is there a way to do this so that the image is scaled down to fit within the 100x100.

cheers
Luke

You could use getimagesize() function to get the dimensions and then fund a scaling factor, say

PHP Code:

$size= getimagesize($_FILES['Photo']['tmp_name']);
$width  = $size[0];    // width of the image
height = $size[1];  
        
if($size[0]>$size[1])
 $scale=$size[0]/100;
else
 $scale=$size[1]/100;

                        
$new_width=    $size[0]/$scale;
$new_height=$size[1]/$scale;
                        
$new_image = imagecreatetruecolor($new_width, $new_height);

Hi Abduraooft,

this loks like what i need the problem i have at the moment is that the images are contained within a rss feed and are pulled out using,

{$item->imageURL}//which gives me the address of the image

so i have used this in your code,

PHP Code:

$size= getimagesize($item->imageURL);
$width  = $size[0];    // width of the image
$height = $size[1];  
        
if($size[0]>$size[1])
 $scale=$size[0]/100;
else
 $scale=$size[1]/100;

                        
$new_width= $size[0]/$scale;
$new_height=$size[1]/$scale;
                        
$new_image = imagecreatetruecolor($new_width, $new_height); 


but i am getting a

Warning: Division by zero in C:\wamp\www\affiliate\test.php on line 150

Warning: Division by zero in C:\wamp\www\affiliate\test.php on line 151

any ideas?

Does your $item->imageURL contain the complete path? If not make it complete by adding the rest of it.
Check Example #3 in http://php.net/getimagesize

$width  = $size[0];    // width of the image
$height = $size[1];  
        
if($size[0]>$size[1])
 $scale=$size[0]/100;
else
 $scale=$size[1]/100;

                        
$new_width= $size[0]/$scale;
$new_height=$size[1]/$scale;
                        
$new_image = imagecreatetruecolor($new_width, $new_height);

print $new_image; 


any ideas
