How can I convert BASE64 encoded HTML to GIF using ColdFusion?

I am receiving a BASE64 encoded string from a WebService. The string represents an HTML page, and I can use built-in ColdFusion functions to convert and display it. However, I need a GIF representation of the HTML page, and I'm wondering if there's any way to do this using ColdFusion.

NOTE: The website I'm working on is ColdFusion 8.

UPDATE: As it turns out, the vendor gave me incorrect instructions (different from their documentation). I don't need to output a GIF of the document they are sending, so this is a non-issue now. However, seeing as the que开发者_如何学Pythonstion has received 6 upvotes already, I'm going to leave the it open, as I'm curious if there is - or will be - an answer someday.

You could save the html to the file system, and use this technique for creating URL Thumbnails

Since CFIMAGE's writeToBrowser doesn't allow you to output a GIF (as you've no doubt found out), you'd have to take the image and save it to the filesystem as a gif, then write an HTML IMG tag pointing to that GIF file.

You can't write a gif but you can take the base64 and write it to the browser as a png.
