CDrawImage::m_bUsingImageAllocator

The m_bUsingImageAllocator member variable indicates whether the allocator for the pin connection is a CImageAllocator object. If the value is TRUE, the allocator is a CImageAllocator object (or is derived from that class).

Syntax

  BOOL m_bUsingImageAllocator;

Remarks

When the value is TRUE, the CDrawImage object can use the GDI BitBlt and StretchBlt functions to render the image, rather than the slower SetDIBitsToDevice and StretchDIBits functions.

Requirements

**  Header:** Declared in Winutil.h; include Streams.h.

**  Library:** Use Strmbase.lib (retail builds) or Strmbasd.lib (debug builds).
