Write some Software

I need a very quick fix on a small piece of Node.js / HTML5 code which is used to flip & rotate images on a canvas. The software is currently rotating and flipping images on a canvas but there needs to be a quick rule wriiten to change specify which images should be flipped, rotated or both. Should be no longer than 15 minutes work. The code for this is currently around 20 lines long so it isn't overly complicated. The code & details will be sent to you over chat. If you say you can / have fixed it then I will award you the project, test and pay right away. Thanks
