# API Description for `PyObjCTools.FndCategories`

## Introduction

The module `PyObjCTools.FndCategories` defines a number of categories on classes from the Foundation framework. These categories introduce new methods that aren’t present in that framework.

To use these new methods use the following code somewhere in your program:

    .. sourcecode:: python

         import PyObjCTools.FndCategories

## Additional methods on `NSAffineTransform`

class PyObjCTools.FndCategories.NSAffineTransform
  rotateByDegrees_atPoint_(angle, point)

    This is simular to `rotateByDegrees_` but rotates around `point` instead of the origin.

  rotateByRadians_atPoint_(angle, point)

    This is simular to `rotateByRadians_` but rotates around `point` instead of the origin.
