need help with image resize script

[acctman]

this is what I have so far... I need to check the image size and if the width is greater than 640w or 600h. I think i have the part correct where it keeps it within an aspect ratio I just need help with getting the width and height and making sure everything else is correct.

 

$src = "/home/site/public_html/images/backup/" . $imagename; 
$imgsize = getimagesize($src);
  	
  // Resize if image is bigger than 640w / 600h		
	if ($width > 640 || $height >= 600 ) {

// Rebuild the image
$target_width = 640;
$target_height = 600;
$target_ratio = $target_width / $target_height;
$img_ratio = $width / $height;
}

if ($target_ratio > $img_ratio) {
	$new_height = $target_height;
	$new_width = $img_ratio * $target_height;
} else {
	$new_height = $target_width / $img_ratio;
	$new_width = $target_width;
}

if ($new_height > $target_height) {
	$new_height = $target_height;
}
if ($new_width > $target_width) {
	$new_height = $target_width;
}

// Image will always be a jpg
$new_img = ImageCreateTrueColor($new_width, $new_height);
if (!@imagecopyresampled($new_img, $img, ($target_width-$new_width)/2, ($target_height-$new_height)/2, 0, 0, $new_width, $new_height, $width, $height)) {
	echo "ERROR:Could not resize image";
	exit(0);
}

// Use a output buffering to load the image into a variable
imagejpeg($new_img);
imagedestroy($new_img);

the width and height are in to $imgsize variable. see http://ca.php.net/manual/en/function.getimagesize.php

This will do it: http://beta.phpsnips.com/snippet.php?id=5

 

If you want it to do transparency, you will need to modify it (I haven't added transparency to the code yet for gif/png images).

how does this function an if statement blow look?

 

function resize($src,$dest) {
$source_pic = ($src);
$destination_pic = ($dest);
$max_width = 500;
$max_height = 600;

$msrc = imagecreatefromjpeg($source_pic);
list($width,$height) = getimagesize($source_pic);

$x_ratio = $max_width / $width;
$y_ratio = $max_height / $height;

if(($width <= $max_width) && ($height <= $max_height)){
    $tn_width = $width;
    $tn_height = $height;
    } elseif (($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;
}

$tmp = imagecreatetruecolor($tn_width,$tn_height);
imagecopyresampled($tmp,$src,0,0,0,0,$tn_width, $tn_height,$width,$height);
imagejpeg($tmp,$destination_pic,100);
imagedestroy($msrc);
imagedestroy($tmp);
}

$width = imageSX($src);
$height = imageSY($src);

if ($width > 500) {
resize($src,$dest);
echo "Copied Image: $imagename\n";
} else {

if(copy($src, $dest)) {
    echo "Copied Image: $imagename\n";
} else {
    echo "Image Copy Failed: $imagename\n";
}
}

does it work?

[acctman]

I know this is a lot to ask but if can someone read through my code and make sure everything looks okay. everything about Watermark image works fine its been test, but i've added a lot of watermarking, resizing and thumbnailing coding at the bottom and i need to make sure that processes everything correctly.
