Definition

Sets *mat_ptr to a scale matrix for the given scale factor for the given axis.


Returns

SE_DRM_STAT_CODE_SUCCESS and *mat_ptr is set appropriately, if valid parameters were passed in.
SE_DRM_STAT_CODE_NULL_REQUIRED_PARAMETER and no changes are made, if
  1. mat_ptr is NULL,
  2. scale_factor is zero, or
  3. axis == SE_LSR_TRNSFRM_AXIS_AXIS_REFERENCE_VECTOR and vec_ptr is NULL
SE_DRM_STAT_CODE_FAILURE - and no changes are made, if axis is not a valid, single axis (X, Y, or Z)
$$$ SE_LSR_TRNSFRM_AXIS_AXIS_REFERENCE_VECTOR is not yet supported

Parameters Notes


mat_ptr

 pointer to the matrix to be set

vec_ptr

 if axis == SE_LSR_TRNSFRM_AXIS_AXIS_REFERENCE_VECTOR, this vector is
    used to specify the axis of scale

axis

 identifies the axis (or axes) along which we're scaling

scale_factor

 the scale factor being used; must be non-zero
