PHP Image Resize Issue

[ATLien]

[code:1:c36122c4ac]function resize($fname, $output, $max_width, $max_height, $quality = 75) {

getimagesize($fname);
$width = $size[0];
$height = $size[1];
$x_ratio = $max_width / $width;
$y_ratio = $max_height / $height;
if ( ($width <= $max_width) && ($height <= $max_height) ) {
$tn_width = $width;
$tn_height = $height;
}
else if (($x_ratio * $height) < $max_height) {
$tn_height = ceil($x_ratio * $height);
$tn_width = $max_width;
}
else {
$tn_width = ceil($y_ratio * $width);
$tn_height = $max_height;
}

$im = imagecreatefromjpeg($fname);
$dst = imagecreatetruecolor($tn_width,$tn_height);
imagecopyresampled($dst, $im, 0, 0, 0, 0,$tn_width,$tn_height,$width,$height);
imagejpeg($dst, $output, $quality);
imagedestroy($im);
imagedestroy($dst);
}
[/code:1:c36122c4ac]

Ok, someone gave me the above code to create a thumb. I want to know what varible I would use to echo the path to the image created in the function. Can anyone help me?

i think its $im or $dst.. not sure though (even though i have worked with the GD library)

Easy thing .....

just correct the code here at the 2nd line in the function

->> getimagesize($fname);

getimagesize returns an array that is used in the rest of the function

correct ->> $size = getimagesize($fname);

it's just a mistyping error.


the output file is the 2nd argument

for ex should be used as follow:
resize("/mypath/image1.jpg","/mypath/thumbs/image1-thumb.jpg", 80,80,100);


I suggest to add some code for the proportions if you intend to have a nice looking thumb
