Resize Image

[enkidu72]

Hello all ,

I'm trying to resize some image , i used to do it with ImageMagick but now i have to change to gd2 , and I'm having much problems ...
That's what I'm trying :
[code]
                                $photo = $_FILES['photo'] ;
                                $temp_photo = $_FILES['photo']['tmp_name'];
                               
                                $sourcename="/var/www/htdocs/gherardo/images/temp/art.jpg";//temporary file
$filename="/var/www/htdocs/gherardo/images/$ref.jpg"; // $ref is the id of the record which the image belong to
copy($temp_photo,$sourcename);

list($width, $height) = getimagesize($sourcename);


$new_width = 300;
$new_height = 300;

$image_p = imagecreatetruecolor($new_width, $new_height);
$image = imagecreatefromjpeg($sourcename);
imagecopyresampled($image_p, $image, 0, 0, 0, 0, $new_width, $new_height, $width, $height);

                            copy( $image_p, $filename );

  [/code]
I think i messed up something ... but dunno what :)
Shouldn't $image_p be the new image , just created and resized ?
Doesn't work at all seems ...
Can someone help me pls ?

Thx in advance

your missing imagejpeg()

also, your dimensions will get mangled if their always set to 300. What if the uploaded image doesn't have the same width and height?

here's a function:
[code]
function resizeImage ($dir, $filename, $maxWidth, $maxHeight, $prefix) {
$size = getimagesize($dir . $filename);
$width = $size[0];
$height = $size[1];

if ($width > $maxWidth || $height > $maxHeight) {
if ($width > $height) {
$newWidth = $maxWidth;
$newHeight = $height * ($maxWidth / $width);
} elseif ($height > $width) {
$newHeight = $maxHeight;
$newWidth = $width * ($maxHeight / $height);
} else {
$newHeight = $maxHeight;
$newWidth = $maxWidth;
}
}

if (isset($newHeight) && isset($newWidth)) {
$img = imagecreatefromjpeg($dir . $filename);
$tmp = imagecreatetruecolor($newWidth, $newHeight);
imagecopyresampled($tmp, $img, 0, 0, 0, 0, $newWidth, $newHeight, $width, $height);
if (!empty($prefix)) $dir .= "thumbs/";
imagejpeg($tmp, $dir . $prefix . $filename);
}
}
[/code[/code]
