IDirectManipulationContent::GetContentTransform method

Retrieves the transform applied to the content.

Syntax

HRESULT GetContentTransform(
  [out] float *matrix,
  [in]  DWORD pointCount
);

Parameters

matrix [out]

The transform matrix.

pointCount [in]

The size of the transform matrix. This value is always 6, because a 3x2 matrix is used for all direct manipulation transforms.

Return value

If the method succeeds, it returns S_OK. Otherwise, it returns an HRESULT error code.

Remarks

This transform contains the default overpan and bounce curves during manipulation and inertia.

This transform does not contain the sync transform set with SyncContentTransform.

The relationship between the three primary transforms is defined as:

Copy

Output transform = Pixel rounding (Sync transform * Content transform)

When this method returns, the format of matrix is:

matrix[0]=ScaleX

matrix[1]=Unused

matrix[2]=Unused

matrix[3]=ScaleY

matrix[4]=TranslateX

matrix[5]=TranslateY
