'''Wren-ellipse''' is a module which enables various curved figures to be drawn or filled within a [https[://rosettacode.org/wiki/Category:DOME |DOME]] script using the Wren programming language. It consists of three classes, Ellipse, Circle and Button. These classes inherit from Selectable (an abstract class in the ''Wren-polygon'' module) which enables the first two as well as the third to be treated as buttons.

It is the twenty-sixth in a series of modules (listed on the language's [https[://rosettacode.org/wiki/Category:Wren |main page]]) designed to assist with writing Rosetta Code tasks so the same code does not have to be written or copy/pasted time and time again thereby bloating a task's script code unnecessarily.

To use it you need to copy the source code (in the [https[://rosettacode.org/wiki/Category_talk:Wren-ellipse |talk page]]) to a text file called ''ellipse.wren'' and place this in the same directory as the importing script so DOME can find it.

Wren-ellipse depends on the graphics and math modules which are part of the DOME framework and also on [https[://rosettacode.org/wiki/Category:Wren-polygon |Wren-polygon]]. As such it can only be used in a DOME script.

As there is a dependency on the ''Wren-polyon'' module, you also need to copy that (if it is not already present) to the same directory as described [https[://rosettacode.org/wiki/Category:Wren-polygon |here]]. However, if you are using any of the classes of that module in the same script, they can be imported via Wren-ellipse itself.
