LoadUseViewPerspective example for C++ 4.0 and later

Note: This topic is for Document/Medical only.

This example times the loading of a bitmap with and without changing the internal view perspective.

// Declare local variables.
CTime StartTime, EndTime;
CTimeSpan DeltaTime;

// Do not include paints when measuring time.
m_Lead1.SetAutoRepaint (FALSE);

// Time the load using the bitmap's view perspective.
m_Lead1.SetLoadUseViewPerspective (TRUE);
StartTime = CTime::GetCurrentTime();

m_Lead1.Load ("d:\\lead\\images\\rotated.tif", 0, 0, 1);
EndTime = CTime::GetCurrentTime();
DeltaTime = EndTime - StartTime;
MessageBox (DeltaTime.Format("%S seconds loaded as is" ), "Notice", MB_OK);

// Time the load that converts the bitmap's view perspective.
m_Lead1.SetLoadUseViewPerspective (FALSE);
StartTime = CTime::GetCurrentTime();
