The GetSourceRect method retrieves the source rectangle. This is an internal method.
Syntax
virtual HRESULT GetSourceRect(
RECT *pSourceRect
) PURE;
Parameters
pSourceRect
Pointer to the retrieved source rectangle.
Return Value
Returns an HRESULT value.
Remarks
This member function must be overridden in the derived class to return the source rectangle held by the video renderer. It is called from the following CBaseControlVideo member functions.
The following example demonstrates an implementation of this function in a derived class.
// Return the current source rectangle
HRESULT CVideoText::GetSourceRect(RECT *pSourceRect)
{
ASSERT(pSourceRect);
m_pRenderer->m_DrawImage.GetSourceRect(pSourceRect);
return NOERROR;
}
In this example, CVideoText is a class derived from CBaseControlVideo, m_pRenderer holds an object of a class derived from CBaseVideoRenderer, and the m_DrawImage data member, defined in the derived class, holds a CDrawImage object.
