MapBoundsOut2In method

Maps the output coordinate space to the input coordinate space.

Syntax

HRESULT retVal = object.MapBoundsOut2In(ulOutIndex, pOutBounds, ulInIndex, pInBounds);

Parameters

  • ulOutIndex [in]
    Type: unsigned long

    Index of the output referred to by pOutBounds. This is usually index zero, because most transforms have only one output.

  • pOutBounds [in]
    Type: DXBNDS

    Pointer to the DXBNDS output bounds to map.

  • ulInIndex [in]
    Type: unsigned long

    Index of the input referred to by pInBounds.

  • pInBounds [out]
    Type: DXBNDS

    Pointer to the resulting input bounds.

Remarks

This method returns the output bounds of the object that is produced if the IDXTransform::Execute method is called, based on the current property settings.
