+title: Stack.generateTransform()
+---
+
+The `Stack.generateTransform()` method generates transforms for the stack,
+sets them as attributes, and returns the original stack.
+
+
+## Stack.generateTransform() signature
+
+```js
+Stack stack.generateTransforms(Object transforms)
+```
+
+The `Stack.generateTransforms()` method takes a single argument,
+an object with the following properties containing the transforms
+to apply:
+
+| Property | Type |Description |
+|----------|------|------------|
+| `move`   | Object | `move.x` and `move.y` are coordinates to which the stack should be translated
+| `rotate` | Number | The number of degrees to rate the stack around its center |
+| `flipX`  | Boolean | Whether to flip the stack along the X axis |
+| `flipY`  | Boolean | Whether to flip the stack along the Y axis |
+
+<Note>This method is chainable as it returns the Stack object</Note>
