Help creating JPG

[rondog]

I am currently generating a thumbnail with this script:

<?php
header("Content-type: image/jpeg");
$src 		= $_GET['fp'];
$img 		= imagecreatefromjpeg("../../../../../".$src);
$width 		= imagesx($img);
$height 	= imagesy($img);
$new_width 	= 150;
$new_height	= floor($height * ($new_width / $width));
$tmp_img 	= imagecreatetruecolor($new_width, $new_height);

imagecopyresized($tmp_img, $img, 0, 0, 0, 0, $new_width, $new_height, $width, $height);
imagejpeg($tmp_img,NULL,40);
imagedestroy($tmp_img);

?>

 

It creates it fine. My question is, while most of them are 16x9 images, their is an occasional 9x16. Is their a way to crop the 9x16 to 16x9 so they are all the same image size?

How do you mean? Crop an image that is 9px width and 16px high, to 16px wide and 9px high? That doesn't make sense, at least to me. How can you crop something to a larger width?

 

You might want to resize it, but that could distort the image.

GD FTW!

Sorry I meant aspect ratio 16x9, not pixels. I def should have specified.

 

Andy that looks like what I need thanks.

That link was golden. I found this function and it works perfect:

function croppedThumbnail($imgSrc,$thumbnail_width,$thumbnail_height) //$imgSrc is a FILE - Returns an image resource.
{ 
    //getting the image dimensions 
    list($width_orig, $height_orig) = getimagesize($imgSrc);  
    $myImage 	= imagecreatefromjpeg($imgSrc);
    $ratio_orig = $width_orig / $height_orig;
   
    if ($thumbnail_width / $thumbnail_height > $ratio_orig)
{
       $new_height 	= $thumbnail_width / $ratio_orig;
       $new_width 	= $thumbnail_width;
    }
else
{
       $new_width 	= $thumbnail_height * $ratio_orig;
       $new_height 	= $thumbnail_height;
    }
   
    $x_mid = $new_width / 2;  //horizontal middle
    $y_mid = $new_height / 2; //vertical middle
   
    $process = imagecreatetruecolor(round($new_width), round($new_height));
   
    imagecopyresampled($process, $myImage, 0, 0, 0, 0, $new_width, $new_height, $width_orig, $height_orig);
    $thumb = imagecreatetruecolor($thumbnail_width, $thumbnail_height);
    imagecopyresampled($thumb, $process, 0, 0, ($x_mid - ($thumbnail_width / 2)), ($y_mid - ($thumbnail_height / 2)), $thumbnail_width, $thumbnail_height, $thumbnail_width, $thumbnail_height);

    imagedestroy($process);
    imagedestroy($myImage);
    return $thumb;
}


$newThumb 	= croppedThumbnail('AnImage.jpg', 150, 86);

header('Content-type: image/jpeg');
imagejpeg($newThumb);
