New image size in variable - Anthony 26/6/2008

This will resize an image and put the new image details into a vairable. You can either use the variable elsewhere in your code or display it. In this case it is reading the width and height; you should be able to use any of the information for -format.

<?php


// Setup the vaiables

$sourceFile = "input.jpg";

$width = "100";

$height = "100";

$destinationFile = "output.png";

// Displays the output size of the new image

$command="convert $sourceFile -resize {$width}x{$height} \( +write $destinationFile \) -format \"%wx%h\" info: ";

$output = exec("$command"); 

print("<b>New image size:</b>".$output."<br>");

?>
