create non-square thumbnail

[deansatch]

I currently have this little bit of code which successfully resizes an image down then crops it square. I want it to crop the center of the image but as a set sized rectangle (220x160) but can't seem to figure it out.

 

$thumb_sizex = 220;
$thumb_sizey = 220;
$size = getimagesize($source);
$width = $size[0];
$height = $size[1];
if($width > $height) {
	$x = ceil(($width - $height) / 2 );
	$width = $height;
} elseif($height > $width) {
	$y = ceil(($height - $width) / 2);
	$height = $width;
}
$new_im = ImageCreatetruecolor($thumb_sizex,$thumb_sizey);	
imagecopyresampled($new_im,$im,0,0,$x,$y,$thumb_sizex,$thumb_sizey,$width,$height);
imagejpeg($new_im,$dest2,100);

 

If I change thumb_sizey to 160 it just stretches the image. It does work on landscape pics but not on portrait. Any help appreciated. NOTE: I don't want to simply shrink it down with a maximum width of 220 or a maximum height of 160. I want the finished dimensions to be 220x160 and crop off any excess.

That seems to be a thread about creating a square thumbnail which I have already done. I wam trying to figure out how to create a set-sized rectangle.

If you look at the script I provided in that thread, it allows you to set the dimensions of the crop.

 

You have the ability to make it square OR rectangular  AND to position where ever you chose on the original

I need it to resize before cropping though. The code on that thread will just crop a portion of the full size image.

Ok, step by step...

 

1. Use your code to resize the image.

      At this point you have created an image to the size you want and have saved it somewhere.

 

2. Run my script to take your resized image and crop the part you want.

 

Now you have the resized image and the cropped image

 

Make sense?

Thanks anyway. I managed to do it in the end with this:

 

 

$size = getimagesize($source);
$image_width = $size[0];
$image_height = $size[1];	
$dest_x = 220;
$dest_y = 160;
if ($image_width > $dest_x or $image_height > $dest_y) {
	if ($image_height >= $image_width){$new_image_width = $dest_x;
$new_image_height = $image_height *($dest_x/$image_width);} 
	else {$new_image_width = $image_width *($dest_y/$image_height); $new_image_height = $dest_y;}
} 
else {$new_image_width = $image_width; $new_image_height = $image_height;}
$new_image = imagecreatetruecolor(220,160);
imagecopyresampled($new_image, $im ,0, 0, 0, 0, $new_image_width, $new_image_height, $image_width, $image_height);
imagejpeg($new_image, $dest, 100);
