I needed to generate invoices based on a template, with data at many different positions on the image, then send it directly to our printer. I wrote this helper function that accepts an image.cfc instance (one that already has my blank image loaded) and writes text to a specific X / Y location on the image. Check it out, and hope it helps someone!
