Hi!

I'd like this code to scale down every original imagesize (no matter what the originalsize would be) into width: 135px and height 75px. Now it only takes one of the to parameters. How do I solve this? The imagequality must be the same.

Here is my code:

// database connection not shown here..

$someImage = "images/webimages/internal/" . $row['picturename']; //fetched from a database


	$mainImage = imagecreatefromjpeg($someImage); 

	$width = 150;
$height = 150;

$mainWidth = imagesx($mainImage);
$mainHeight = imagesy($mainImage);



$ratio_orig = $mainWidth/$mainHeight;

if ($width/$height > $ratio_orig) {
   $width = $height*$ratio_orig;
} else {
   $height = $width/$ratio_orig;
}


$image_p = imagecreatetruecolor($width, $height);

imagecopyresampled($image_p, $mainImage, 0, 0, 0, 0, $width, $height, $mainWidth, $mainHeight);

// Output
imagejpeg($image_p, null, 100);

oaskedal,

you have BOTH a height and width property in your script...

Just set them to the size (in pixels) that you want, and get rid of the proportion/ration bit.

Here is an example using an image called "angelina.jpg":

<?php
header("Content-type: image/jpg");
$mainImage = imagecreatefromjpeg('angelina.jpg');
$width = 135;
$height = 75;
$mainWidth = imagesx($mainImage);
$mainHeight = imagesy($mainImage);

$image_p = imagecreatetruecolor($width,$height);
imagecopyresampled($image_p,$mainImage,0,0,0,0,$width,$height,$mainWidth,$mainHeight);
imagejpeg($image_p, null, 100); 
?>

Thank you! Now it works all fine! Just one more thing - what if the actual imagefile is on another page, and I'd like this script to fetch that file and output it in the right proportion.

Thanks again!
