Restricting Image Width with Image Magick

[crondeau]

Hi does anyone know how to mogrify an image and set the width to 200 px and not worry about the height. I want all my images to be 200 px wide.

At the moment this works

exec("/usr/bin/mogrify -resize 200x150 ".$Dir.'/'.$fileName);

and I tried

exec("/usr/bin/mogrify -resize 200!x150 ".$Dir.'/'.$fileName);

and

exec("/usr/bin/mogrify -resize 200x ".$Dir.'/'.$fileName);

but that doesn't seem to work

Thanks in advance Christine

Hi Christine,

Did you ever figure this out? I need to do something similar.

Thanks,

Hey John,

I did figure it out. I used an if/else to check the image size and then carried out the mogrify.

	
if(move_uploaded_file($_FILES['uploadFile']['tmp_name'], putDirectory.'/'.$fileName))

{
exec("/bin/chmod 777 ".$putDirectory.'/'.$fileName);
$Dir = str_replace("/name_of_directory/www","images",($putDirectory));
//resize images using image magick
$size = getimagesize($Dir.'/'.$fileName);
 	if ($size[0] >= '200')
{
   	$width = '200';
  	$height = $size[1] * ($width / $size[0]);
 	}
else
{
  	$width = $size[0];
  	$height = $size[1];
}
exec("/usr/bin/mogrify -resize ".$width.'x'.$height.' '.$Dir.'/'.$fileName);


$errMsg .= 'Image '.$fileName.' was successfully uploaded to '.$putDirectory;
			$errMsg .= '<br>Resized image:'.$width.'x'.$height;
			}
			else
			{
				$errMsg .= 'image was not uploaded';
			}
