Are there any drawing plugins for RoR or jQuery?

Question

I am writing a web application using Ruby on Rails. In one form, users will need to draw something with the mouse and apply text to the object with some text. In short, I need

• Simple paint, like an application on which I can draw with the mouse.
• Write plain text.
• Save the colored chart as a file for later editing.
• Export the painful chart as a gif / jpeg image.

An example can be found at http://charles-harvey.co.uk/examples/paint/ . Here are my questions:

• Are there any RoR plugins that allow me to add a drawn object to the form?
• If there are no jQuery plugins that have a simple drawing application that I can include on rails?
• Other pointers?

I can write a simple canvas application, but I am in a very tight deadline and prefer to use what has already been verified.

PS: I found a link for such an application, but forgot to tag it.
