Copy constructor for CachedBitmap.

Syntax

void CachedBitmap(
  const CachedBitmap & unnamedParam1
);

Parameters

unnamedParam1

The object to copy into this object.

You can display a cached bitmap by passing the address of a CachedBitmap::CachedBitmap object to the DrawCachedBitmap method of a Graphics object. Use the Graphics object that was passed to the CachedBitmap::CachedBitmap constructor or another Graphics object that represents the same device.

Examples

The following example creates a CachedBitmap::CachedBitmap object based on a Bitmap object and a Graphics object. The code calls the DrawCachedBitmap method of that Graphics object to display the cached bitmap.

VOID Example_CachedBitmap(HDC hdc)
{
   Graphics graphics(hdc);
   Bitmap bitmap(L"Grapes.jpg");
   CachedBitmap cachedBitmap(&bitmap, &graphics);

   graphics.DrawCachedBitmap(&cachedBitmap, 10, 10);  
}
