## Detailed Description

Function set for scaling in time.

This function set is used for keyframe deltas of type MFn::kKeyframeDeltaScale. These deltas are generated from scaling events. Particularly scaling on the time axis. Changes in value are recorded as a MFnKeyframeDeltaMove.

`#include <MFnKeyframeDeltaScale.h>`

## Constructor & Destructor Documentation

MFnKeyframeDeltaScale | ( | MObject & | object,
|  | MStatus * | ReturnStatus = `NULL`
| ) |  |

Constructor.

Class constructor that initializes the function set to the given MObject.

Parameters:

  [in] | object | The MObject to attach the function set to
  [out] | ReturnStatus | the return status

Status Codes:
  - MS::kSuccess if the function set is successfully attached
  - MS::kInvalidParameter if the MObject does not represent a valid Maya object or if the function set is not allowed to attach to this MObject

MFnKeyframeDeltaScale | ( | const MObject & | object,
|  | MStatus * | ReturnStatus = `NULL`
| ) |  |

Constructor.

Class constructor that initializes the function set to the given MObject.

Parameters:

  [in] | object | The MObject to attach the function set to
  [out] | ReturnStatus | the return status

Status Codes:
  - MS::kSuccess if the function set is successfully attached
  - MS::kInvalidParameter if the MObject does not represent a valid Maya object or if the function set is not allowed to attach to this MObject
