How do I update my extra_filters module to work with latest release (due to some new redirect/argument issues)?

Hello,
Some time ago I made an extra_filters_logo_resize module to work with imagecache actions. With updates made about a month ago, I started getting some really odd url "temporary redirect" issues with new logo images I uploaded. I updated to the latest dev version yesterday, and the issues still remain.

The log mentions a ton of 'invalid argument supplied' errors for the $image variable I'm passing in. Has the extra_filters handling changed recently? here's a sample of my module:

<?php
function extra_filters_logo_resize_image(&$image, $data = array()) {
  $maxWidth = $data['maxWidth'] ? $data['maxWidth'] : 240;
  $maxHeight = $data['maxHeight'] ? $data['maxHeight'] : 240;
  $maxArea = $data['maxArea'] ? $data['maxArea'] : 18000;
  $canvasWidth = $data['canvasWidth'] ? $data['canvasWidth'] : 0;
  $canvasHeight = $data['canvasHeight'] ? $data['canvasHeight'] : 0;
  $image = ResizeLogo($image, $maxWidth, $maxHeight, $maxArea, $canvasWidth, $canvasHeight);
  return true;
}

function ResizeLogo(&$image, $maxWidth, $maxHeight, $maxArea, $canvasWidth, $canvasHeight) {
...
}
?>

Let me know your thoughts. I have people breathing down my neck while I troubleshoot this. Your feedback is greatly appreciated. :D

Best regards,

Chris
