New image size in variable ( Anthony 27/6/2008 )
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.
IM code:
<?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>");
?>
